如何在.Net C中将二进制文件从MemoryStream加载到WebBrowser中＃ [英] How to load binary from MemoryStream into WebBrowser in .Net C#

问题描述

  string  fileName =  @  C：\Users\test1.pdf; 
  byte  [] buff =  null ; 
 FileStream fs =  new  FileStream（fileName，
 FileMode.Open，FileAccess.Read）; 
 BinaryReader br =  new  BinaryReader（fs）; 
  long  numBytes =  new  FileInfo（fileName）.Length; 
 buff = br.ReadBytes（（ int ）numBytes）; 
 MemoryStream stream =  new  MemoryStream（buff）; 
 webBrowser1.DocumentStream = stream; 
 webBrowser1.Show（）; 

解决方案

试试这个..



byte [] yourByteData = ..在这里分配你的pdf数据....

Response.ClearHeaders（）;

Response.Clear（）;

Response.AddHeader（Content-Type，application / pdf）;

Response.AddHeader（Content-Length，yourByteData.Length.ToString（））;

Response.AddHeader（Content-Disposition，inline; filename = sample.pdf）;

Response.BinaryWrite（yourByteData）;

Response.Flush（）;

Response.End（）;

这一行非常重要

联;文件名

string fileName = @"C:\Users\test1.pdf";
byte[] buff = null;
FileStream fs = new FileStream(fileName,              
             FileMode.Open,FileAccess.Read);
BinaryReader br = new BinaryReader(fs);
long numBytes = new FileInfo(fileName).Length;
buff = br.ReadBytes((int) numBytes);
MemoryStream stream = new MemoryStream(buff);
webBrowser1.DocumentStream = stream;
webBrowser1.Show();

解决方案

Try this..

byte[] yourByteData = .. assign your pdf data here ....
Response.ClearHeaders();
Response.Clear();
Response.AddHeader("Content-Type","application/pdf");
Response.AddHeader("Content-Length",yourByteData.Length.ToString());
Response.AddHeader("Content-Disposition","inline; filename=sample.pdf");
Response.BinaryWrite(yourByteData);
Response.Flush();
Response.End();

This line is important

inline; filename
