Dynamically create Folder (Directory) inside another in FTP server using C# and VB.Net in ASP.Net

Hi namojainashis...,

Refer below sample code.

C#

protected void Page_Load(object sender, EventArgs e)
{
    string rootFolder = Server.MapPath("~/UploadDocument/");
    string[] documents = new[] { "DocumentID_123_Project ID_2345", "DocumentID_12322_Project ID_234235" };
    foreach (string document in documents)
    {
        string folder = System.IO.Path.Combine(rootFolder, document);
        if (!System.IO.Directory.Exists(folder))
        {
            System.IO.Directory.CreateDirectory(folder);
        }
    }
}

VB.Net

Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
    Dim rootFolder As String = Server.MapPath("~/UploadDocument/")
    Dim documents As String() = {"DocumentID_123_Project ID_2345", "DocumentID_12322_Project ID_234235"}
    For Each document As String In documents
        Dim folder As String = System.IO.Path.Combine(rootFolder, document)
        If Not System.IO.Directory.Exists(folder) Then
            System.IO.Directory.CreateDirectory(folder)
        End If
    Next
End Sub

For creating in ftp server refer below code.

C#

string rootAddeess = "ftp://yourserver.com/UploadDocument";
string[] subDirectories = new[] { "DocumentID_123_Project ID_2345", "DocumentID_12322_Project ID_234235" };
foreach (string subDirectory in subDirectories)
{
    System.Net.WebRequest request = System.Net.WebRequest.Create(rootAddeess + "/" + subDirectory);
    request.Method = System.Net.WebRequestMethods.Ftp.MakeDirectory;
    request.Credentials = new System.Net.NetworkCredential("UserName", "Password");
    using (var response = (System.Net.FtpWebResponse)request.GetResponse())
    {
                
    }
}

VB.Net

Dim rootAddeess As String = "ftp://yourserver.com/UploadDocument"
Dim subDirectories As String() = {"DocumentID_123_Project ID_2345", "DocumentID_12322_Project ID_234235"}
For Each subDirectory As String In subDirectories
    Dim request As System.Net.WebRequest = System.Net.WebRequest.Create(rootAddeess & "/" & subDirectory)
    request.Method = System.Net.WebRequestMethods.Ftp.MakeDirectory
    request.Credentials = New System.Net.NetworkCredential("UserName", "Password")
    Using response = CType(request.GetResponse(), System.Net.FtpWebResponse)
    End Using
Next
