myFileCollection = Request.Files
myFile = myFileCollection ( 0 )
FileLen = myFile.ContentLength
Dim Input ( FileLen ) As Byte
' Initialize the stream.
MyStream = myFile.InputStream
' Read the file into the byte array.
MyStream.Read ( input, 0, FileLen )
' Copy the byte array into a string.
For Loop1 = 0 To FileLen-1
MyString = MyString & Input ( Loop1 ).ToString ( )
Next Loop1
[ C# ]
HttpFileCollection myFileCollection;
HttpPostedFile myFile;
int FileLen;
System.IO.Stream MyStream;
myFileCollection = Request.Files;
myFile = myFileCollection [ 0 ];
FileLen = myFile.ContentLength;
byte [ ] input = new byte [ FileLen ];
// Initialize the stream.
MyStream = myFile.InputStream;
// Read the file into the byte array.
MyStream.Read ( input, 0, FileLen );
