Save image send from other page into Directory (Folder) using C# and VB.Net in ASP.Net

HiBhavesh23,

You have to use HiddenField for saving the data.

Refer below sample.

HTML

Default

<table border="0" cellpadding="0" cellspacing="0">
    <tr>
        <td>Name:
        </td>
        <td>
            <input type="text" id="txtName" readonly="readonly" />
        </td>
    </tr>
    <tr>
        <td></td>
        <td>
            <img id="imgPerson" runat="server" />
            <asp:HiddenField ID="hfUrl" runat="server" />
        </td>
    </tr>
    <tr>
        <td></td>
        <td>
            <input type="button" value="Select Name" onclick="Select()" />
        </td>
    </tr>
</table>
<br />
<asp:Button Text="Save" runat="server" OnClick="OnSave" />
<script type="text/javascript">
    var popup;
    function Select() {
        popup = window.open("Popup.aspx", "Popup", "width=200,height=200");
        popup.focus();
    }
    function SetSource(src) {
        document.getElementById("imgPerson").src = src;
        document.getElementById("hfUrl").value = src;
    }
</script>

Popup

<select name="ddlNames" id="ddlNames">
    <option value="Mudassar Khan">Mudassar Khan</option>
    <option value="John Hammond">John Hammond</option>
    <option value="Mike Stanley">Mike Stanley</option>
</select>
<br />
<img id="img" src="Images/Penguins.jpg" />
<br />
<input type="button" value="Select" onclick="SetName();" />
<script type="text/javascript">
    function SetName() {
        if (window.opener != null && !window.opener.closed) {
            var txtName = window.opener.document.getElementById("txtName");
            var imgPerson = window.opener.document.getElementById("imgPerson");
            txtName.value = document.getElementById("ddlNames").value;
            window.opener.SetSource(document.getElementById("img").src);
        }
        window.close();
    }
</script>

Code

Default

C#

protected void OnSave(object sender, EventArgs e)
{
    string image = hfUrl.Value;
    var webClient = new WebClient();
    byte[] imageBytes = webClient.DownloadData(image);

    string MainDir = @"~/VisiterImage/";
    string SubDir = DateTime.Now.ToString("dd-MM-yyyy");

    if (!Directory.Exists(Server.MapPath(MainDir)))
    {
        Directory.CreateDirectory(Server.MapPath(MainDir));
    }
    if (!Directory.Exists(Server.MapPath(MainDir + SubDir)))
    {
        Directory.CreateDirectory(Server.MapPath(MainDir + SubDir));
    }

    string imageName = "Image.jpg";
    File.WriteAllBytes(Path.Combine(Server.MapPath(MainDir + SubDir), imageName), imageBytes);
    // Code to save the byte data imageBytes in database.
}

VB.Net

Protected Sub OnSave(ByVal sender As Object, ByVal e As EventArgs)
    Dim image As String = hfUrl.Value
    Dim webClient = New WebClient()
    Dim imageBytes As Byte() = webClient.DownloadData(image)
    Dim MainDir As String = "~/VisiterImage/"
    Dim SubDir As String = DateTime.Now.ToString("dd-MM-yyyy")

    If Not Directory.Exists(Server.MapPath(MainDir)) Then
        Directory.CreateDirectory(Server.MapPath(MainDir))
    End If

    If Not Directory.Exists(Server.MapPath(MainDir & SubDir)) Then
        Directory.CreateDirectory(Server.MapPath(MainDir & SubDir))
    End If

    Dim imageName As String = "Image.jpg"
    File.WriteAllBytes(Path.Combine(Server.MapPath(MainDir & SubDir), imageName), imageBytes)
    ' Code to save the byte data imageBytes in database.
End Sub
