Maximum request size can be specified in the Machine.config or Web.config file in the maxRequestLength attribute of the httpRuntime Element (ASP.NET Settings Schema) element. The maximum request size for a specific page can be specified using the location Element (ASP.NET Settings Schema) element in a Web.config file.
The following code example demonstrates how to save all the files that are uploaded by the client to the C:\TempFiles folder on the Web server's local disk.
Dim Loop1 As Integer
Dim TempFileName As String
Dim MyFileCollection As HttpFileCollection = Request.Files
For Loop1 = 0 To MyFileCollection.Count - 1
' Create a new file name.
TempFileName = "C:\TempFiles\File_" & CStr(Loop1)
' Save the file.
MyFileCollection(Loop1).SaveAs(TempFileName)
Next Loop1
String TempFileName;
HttpFileCollection MyFileCollection = Request.Files;
for (int Loop1 = 0; Loop1 < MyFileCollection.Count; Loop1++)
{
// Create a new file name.
TempFileName = "C:\\TempFiles\\File_" + Loop1.ToString();
// Save the file.
MyFileCollection[Loop1].SaveAs(TempFileName);
