download a folder from server to local host
I have a code to downolad a particular file that is stored at a particular location on the server...
for example i have a file untitled.bmp in the C: drive of my server and i download this to my localhost using the particular code...
protected void Button1_Click(object sender, EventArgs e)
{
string filepath = (@"C:\untitled.bmp");
// Create New instance of FileInfo class to get the properties of the file being downloaded
FileInfo myfile = new FileInfo(filepath);
// Checking if file exists
if (myfile.Exists)
{
// Clear the content of the response
Response.ClearContent();
// Add the file name and attachment, which will force the open/cancel/save dialog box to show, to the header
Response.AddHeader("Content-Disposition", "attachment; filename=" + myfile.Name);
// Add the file size into the response header
Response.AddHeader("Content-Length", myfile.Length.ToString());
// Set the ContentType
Response.ContentType = ReturnExtension(myfile.Extension.ToLower());
// Write the file into the response (TransmitFile is for ASP.NET 2.0. In ASP.NET 1.1 you have to use WriteFile instead)
Response.TransmitFile(myfile.FullName);
// End the response
Response.End();
}
}
private string ReturnExtension(string fileExtension)
{
switch (fileExtension)

now my problem is how do i download a folder with multiple files in it.. is there a way???
for example i have a folder named recovery in C: drive which contains two files untitled.bmp and test.txt...
thanks...
I need to do this without zipping... please suggest a way...
For multiple files, you'll need to pack them together as, for instance, a ZIP file.
Downloading Multiple Files as a Zip File Using GridView and SharpZipLib
You could zip the files together (e.g. untitled.bmp and test.txt) and then download them as a single file.
