In this article I will explain how to upload and save MP3 Audio files in SQL Server Database and then retrieving and displaying in ASP.Net GridView with download and play option
Upload and save and retrieve MP3 Audio files from SQL Server database using C# and VB.Net
 
Database
For this article I have created a simple table with the following structure
Upload and save and retrieve MP3 Audio files from SQL Server database using C# and VB.Net
 
HTML Markup
The HTML Markup contains a FileUpload and Button to upload and save the MP3 files to database and an ASP.Net GridView control to display the uploaded files and also allows the user to play and download the MP3 Audio file.
<asp:FileUpload ID="FileUpload1" runat="server" />
<asp:Button ID="btnUpload" runat="server" Text="Upload"
    onclick="btnUpload_Click" />
<hr />
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" RowStyle-BackColor="#A1DCF2" Font-Names = "Arial" Font-Size = "10pt"
HeaderStyle-BackColor="#3AC0F2" HeaderStyle-ForeColor="White">
    <Columns>
        <asp:BoundField DataField="Name" HeaderText="FileName" />
        <asp:TemplateField>
            <ItemTemplate>
                <object type="application/x-shockwave-flash" data='dewplayer-vol.swf?mp3=File.ashx?Id=<%# Eval("Id") %>'
                    width="240" height="20" id="dewplayer">
                    <param name="wmode" value="transparent" />
                    <param name="movie" value='dewplayer-vol.swf?mp3=File.ashx?Id=<%# Eval("Id") %>'/>
                object>
            ItemTemplate>
        asp:TemplateField>
        <asp:HyperLinkField DataNavigateUrlFields="Id" Text = "Download" DataNavigateUrlFormatString = "~/File.ashx?Id={0}" HeaderText="Download" />
    Columns>
asp:GridView>
 
Note: For playing MP3 files I am using Flash MP3 player to know more about it refer my article

Note: The File.ashx is a Generic Handler (explained later) which is used to fetch the uploaded MP3 files from the SQL Server database for the purpose of Playing and Downloading.
 

Uploading the MP3 Audio files and saving in SQL Server Database
The below event handler gets executed when the Upload Button is clicked, it simply saves the file as Binary data in the SQL Server Database
C#
protected void btnUpload_Click(object sender, EventArgs e)
{
    using (BinaryReader br = new BinaryReader(FileUpload1.PostedFile.InputStream))
    {
        byte[] bytes = br.ReadBytes((int)FileUpload1.PostedFile.InputStream.Length);
        string strConnString = ConfigurationManager.ConnectionStrings["constr"].ConnectionString;
        using (SqlConnection con = new SqlConnection(strConnString))
        {
            using (SqlCommand cmd = new SqlCommand())
            {
                cmd.CommandText = "insert into tblFiles(Name, ContentType, Data) values (@Name, @ContentType, @Data)";
                cmd.Parameters.AddWithValue("@Name", Path.GetFileName(FileUpload1.PostedFile.FileName));
                cmd.Parameters.AddWithValue("@ContentType", "audio/mpeg3");
                cmd.Parameters.AddWithValue("@Data", bytes);
                cmd.Connection = con;
                con.Open();
                cmd.ExecuteNonQuery();
                con.Close();
            }
        }
    }
    Response.Redirect(Request.Url.AbsoluteUri);
}
 
VB.Net
Protected Sub btnUpload_Click(sender As Object, e As EventArgs)
    Using br As New BinaryReader(FileUpload1.PostedFile.InputStream)
        Dim bytes As Byte() = br.ReadBytes(CInt(FileUpload1.PostedFile.InputStream.Length))
        Dim strConnString As String = ConfigurationManager.ConnectionStrings("constr").ConnectionString
        Using con As New SqlConnection(strConnString)
            Using cmd As New SqlCommand()
                cmd.CommandText = "insert into tblFiles(Name, ContentType, Data) values (@Name, @ContentType, @Data)"
                cmd.Parameters.AddWithValue("@Name", Path.GetFileName(FileUpload1.PostedFile.FileName))
                cmd.Parameters.AddWithValue("@ContentType", "audio/mpeg3")
                cmd.Parameters.AddWithValue("@Data", bytes)
                cmd.Connection = con
                con.Open()
                cmd.ExecuteNonQuery()
                con.Close()
            End Using
        End Using
    End Using
    Response.Redirect(Request.Url.AbsoluteUri)
End Sub
 
 
Displaying the uploaded MP3 Audio files in ASP.Net GridView
Below is the code which populates the ASP.Net GridView from data from the table which contains the uploaded MP3 files.
C#
protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        BindGrid();
    }
}
 
private void BindGrid()
{
    string strConnString = ConfigurationManager.ConnectionStrings["constr"].ConnectionString;
    using (SqlConnection con = new SqlConnection(strConnString))
    {
        using (SqlCommand cmd = new SqlCommand())
        {
            cmd.CommandText = "select Id, Name from tblFiles";
            cmd.Connection = con;
            con.Open();
            GridView1.DataSource = cmd.ExecuteReader();
            GridView1.DataBind();
            con.Close();
        }
    }
}
 
VB.Net
Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load
    If Not IsPostBack Then
        BindGrid()
    End If
End Sub
 
Private Sub BindGrid()
    Dim strConnString As String = ConfigurationManager.ConnectionStrings("constr").ConnectionString
    Using con As New SqlConnection(strConnString)
        Using cmd As New SqlCommand()
            cmd.CommandText = "select Id, Name from tblFiles"
            cmd.Connection = con
            con.Open()
            GridView1.DataSource = cmd.ExecuteReader()
            GridView1.DataBind()
            con.Close()
        End Using
    End Using
End Sub
 
 
Playing and Download the MP3 Audio files from ASP.Net GridView
I have made use of a Generic Handler which will fetch the uploaded MP3 audio file based on Id when user wants to play in the Music or download it using the Download link.
C#
<%@ WebHandler Language="C#" Class="FileCS" %>
 
using System;
using System.Web;
using System.Data.SqlClient;
using System.Configuration;
public class FileCS : IHttpHandler
{
    public void ProcessRequest(HttpContext context)
    {
        int id = int.Parse(context.Request.QueryString["id"]);
        byte[] bytes;
        string contentType;
        string strConnString = ConfigurationManager.ConnectionStrings["constr"].ConnectionString;
        string name;
        using (SqlConnection con = new SqlConnection(strConnString))
        {
            using (SqlCommand cmd = new SqlCommand())
            {
                cmd.CommandText = "select Name, Data, ContentType from tblFiles where Id=@Id";
                cmd.Parameters.AddWithValue("@Id", id);
                cmd.Connection = con;
                con.Open();
                SqlDataReader sdr = cmd.ExecuteReader();
                sdr.Read();
                bytes = (byte[])sdr["Data"];
                contentType = sdr["ContentType"].ToString();
                name = sdr["Name"].ToString();
                con.Close();
            }
        }
        context.Response.Clear();
        context.Response.Buffer = true;
        context.Response.AppendHeader("Content-Disposition", "attachment; filename=" + name);
        context.Response.ContentType = contentType;
        context.Response.BinaryWrite(bytes);
        context.Response.End();
    }
 
    public bool IsReusable
    {
        get
        {
            return false;
        }
    }
}
 
VB.Net
<%@ WebHandler Language="VB" Class="FileVB" %>
 
Imports System
Imports System.Web
Imports System.Data.SqlClient
Imports System.Configuration
 
Public Class FileVB : Implements IHttpHandler
   
    Public Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest
        Dim id As Integer = Integer.Parse(context.Request.QueryString("id"))
        Dim bytes As Byte()
        Dim contentType As String
        Dim strConnString As String = ConfigurationManager.ConnectionStrings("constr").ConnectionString
        Dim name As String
        Using con As New SqlConnection(strConnString)
            Using cmd As New SqlCommand()
                cmd.CommandText = "select Name, Data, ContentType from tblFiles where Id=@Id"
                cmd.Parameters.AddWithValue("@Id", id)
                cmd.Connection = con
                con.Open()
                Dim sdr As SqlDataReader = cmd.ExecuteReader()
                sdr.Read()
                bytes = DirectCast(sdr("Data"), Byte())
                contentType = sdr("ContentType").ToString()
                name = sdr("Name").ToString()
                con.Close()
            End Using
        End Using
        context.Response.Clear()
        context.Response.Buffer = True
        context.Response.AppendHeader("Content-Disposition", "attachment; filename=" + name)
        context.Response.ContentType = contentType
        context.Response.BinaryWrite(bytes)
        context.Response.End()
    End Sub
 
    Public ReadOnly Property IsReusable() As Boolean Implements IHttpHandler.IsReusable
        Get
            Return False
        End Get
    End Property
End Class
