Public ReadOnly Property InputStream As Stream

Eigenschaftswert

Ein Stream, der auf eine Datei zeigt.

Beispiele

Das folgende Codebeispiel zeigt, wie Sie den Inhalt der ersten Datei in der Dateiauflistung des Clients in ein Bytearray lesen und dann das Bytearray in eine Zeichenfolge kopieren.

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
