Examples
The following code example shows how to read the contents of the first file in the client's file collection into a byte array, and then copy the byte array to a string.
using System;
using System.Web;
using System.Web.UI;
public class Page1: Page
{
protected string MyString;
private void Page_Load(Object sender, EventArgs e)
{
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);
// Copy the byte array into a string.
for (int Loop1 = 0; Loop1 < FileLen; Loop1++)
MyString = MyString + input[Loop1].ToString();
}
}
Imports System.Web
Imports System.Web.UI
Public Class Page1: Inherits Page
Protected Loop1 As Integer
Protected MyString As String
Protected Sub Page_Load(sender As Object, e As EventArgs)
Dim MyFileCollection As HttpFileCollection
Dim MyFile As HttpPostedFile
Dim FileLen As Integer
Dim MyString As String
Dim MyStream As System.IO.Stream
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
End Sub
End Class
