I am not sure what the problem is but this works for me in both you could try it out ....Let me know if it works out

C#

if (File.Exists(filepath)) {
	
	string filename = Path.GetFileName(filepath);
	Response.Clear();
	Response.ContentType = GetMimeTypeByFileName(filename);
	Response.AddHeader("Content-Disposition", "attachment; filename=\"" + filename + "\"");
	Response.AddHeader("Content-Length", mfile.Length.ToString());
	Response.TransmitFile(filepath);
	Response.End();
}

The Function GetMimeTypeByFileName(filename) is below

C#

public string GetMimeTypeByFileName(string sFileName)
{
	string sMime = "application/octet-stream";

	string sExtension = System.IO.Path.GetExtension(sFileName);
	if (!string.IsNullOrEmpty(sExtension)) {
		sExtension = sExtension.Replace(".", "");
		sExtension = sExtension.ToLower();

		if (sExtension == "xls" || sExtension == "xlsx") {
			sMime = "application/ms-excel";
		} else if (sExtension == "pdf") {
			sMime = "application/pdf";
		} else if (sExtension == "doc" || sExtension == "docx") {
			sMime = "application/msword";
		} else if (sExtension == "ppt" || sExtension == "pptx") {
			sMime = "application/ms-powerpoint";
		} else if (sExtension == "rtf") {
			sMime = "application/rtf";
		} else if (sExtension == "zip") {
			sMime = "application/zip";
		} else if (sExtension == "mp3") {
			sMime = "audio/mpeg";
		} else if (sExtension == "bmp") {
			sMime = "image/bmp";
		} else if (sExtension == "gif") {
			sMime = "image/gif";
		} else if (sExtension == "jpg" || sExtension == "jpeg") {
			sMime = "image/jpeg";
		} else if (sExtension == "png") {
			sMime = "image/png";
		} else if (sExtension == "tiff" || sExtension == "tif") {
			sMime = "image/tiff";
		} else if (sExtension == "txt") {
			sMime = "text/plain";
		}
	}

	return sMime;
}
