Save BinaryWrite to Server Path

Question

I am saving files to SQL Server on remote hosted server. I can upload them. But I need to download a file to the remote servers path. The code below extracts the file but saves it to the client.

I tried replacing Response.BinaryWrite(bytes) to Response.TransmitFile( Server.MapPath("~/App_Data/DS/sailbig.jpg") but I get an error file not found.

I simply want to extract the file I stored in sql and place it a the directory on the server so I can use it in code later, but I cannot figure it out. Any help is appreciated, this is a hobby for me.

    Dim filePath As String = HttpContext.Current.Server.MapPath("~/App_Data/DS/")
    Dim bytes() As Byte = CType(dt.Rows(0)("Data"), Byte())
    response.Buffer = True
    response.Charset = ""
    response.Cache.SetCacheability(HttpCacheability.NoCache)
    response.ContentType = dt.Rows(0)("ContentType").ToString()
    Response.AddHeader("content-disposition", "attachment;filename=" & dt.Rows(0)("FileName").ToString())
    Response.BinaryWrite(bytes)
    Response.Flush()
    Response.End()

Use File.WriteAllBytes :

Dim filePath As String = HttpContext.Current.Server.MapPath("~/App_Data/DS/")
Dim bytes() As Byte = CType(dt.Rows(0)("Data"), Byte())

File.WriteAllBytes(filePath & dt.Rows(0)("FileName").ToString(), bytes)
