Exemplos

O seguinte exemplo de código mostra como ler o conteúdo do primeiro ficheiro da coleção de ficheiros do cliente num array de bytes e depois copiar o array de bytes para uma 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
