怎样下载网页成.NET流 [英] How do I download a webpage into a stream in .NET

问题描述

我知道这应该是一个基本的问题，但我打砖墙。 我期待去一个URL / URI下载得到的字符串，如果我打开一个文件，然后把它弄出来到字符串变量。

我一直在馅大约有IO.Stream和Net.httpxxx，但还没有设法让元素排队以正确的方式。

我得到不支持给定路径的格式从标准流打开该网页，因为它不是在本地文件系统......这一点我明白了，有点我不明白的是...我怎么做到的equivelent：

 公共功能GetWebPageAsString（的pURL作为字符串）作为字符串
        昏暗lStream作为IO.StreamReader =新就是System.IO.StreamReader（的pURL）
        返回lStream.ReadToEnd

端功能
 

解决方案

简短的回答，在C＃中，看起来像

 使用（System.Net.WebClient客户端=新System.Net.WebClient（））
{
  字符串的HTML = client.DownloadString（http://www.google.com）;
}
 

I know this should be a basic question but I am hitting a brick wall. I am looking to go to a URL/URI download the resulting string as if I had opened a file and then get it out into a String variable.

I have been stuffing about with IO.Stream and Net.httpxxx but haven't managed to get the elements to line up in the right way.

I get "the given path's format is not supported" from opening the page in the standard stream, because it's not in the local file system ... that bit i understand, the bit I don't get is ... how do I achieve the equivelent of:

Public Function GetWebPageAsString(pURL As String) As String
        Dim lStream As IO.StreamReader = New System.IO.StreamReader(pURL)
        Return lStream.ReadToEnd

End Function

解决方案

The short answer, in C#, looks like

using(System.Net.WebClient client = new System.Net.WebClient())
{
  string html = client.DownloadString("http://www.google.com");
}
