在PowerShell中V2编译新型 - 曲奇意识到Web客户端 [英] Compiling new type in PowerShell v2 - Cookie Aware WebClient

问题描述

我试图编译的<一个是饼干意识到版 HREF =http://msdn.microsoft.com/en-us/library/system.net.webclient.aspx> WebClient的类 - 但我似乎无法克服的一些使用的障碍在PowerShell中V2加入添加型cmdlet的。这里是我试图编译的代码：

I am trying to compile a "cookie aware" version of the WebClient class - but I can't seem to get over some of the hurdles of using the Add-Type cmdlet added in PowerShell v2. Here is the code I am trying to compile:

PS C:\> $def = @"
public class CookieAwareWebClient : System.Net.WebClient
{
  private System.Net.CookieContainer m_container = new System.Net.CookieContainer();
  protected override System.Net.WebRequest GetWebRequest(System.Uri address)
  {
    System.Net.WebRequest request = base.GetWebRequest(address);
    if (request is System.Net.HttpWebRequest)
    {
      (request as System.Net.HttpWebRequest).CookieContainer = m_container;
    }
    return request;
  }
}
"@

PS C:\> Add-Type -TypeDefinition $def

它似乎无法找到的CookieContainer类型不能为发现（虽然它是完全合格的...） - 显然我的东西盲目

It can't seem to find the CookieContainer type can't be found (though it is fully qualified...) - clearly I am blind on something.

编辑：更新示例代码是正确的。复制正pasteable，谢谢！

Updated the sample code to be correct and copy-n-pasteable, thanks!

推荐答案

第二个参照的CookieContainer 通过构造函数表达式是完全合格的。第一个参考，声明字段时， m_container 不是。使双方完全合格因此Powershell的可以找到他们。

The second reference to CookieContainer with the constructor expression is fully qualified. The first reference, when declaring the field m_container is not. Make both fully qualified so Powershell can find them

private System.Net.CookieContainer m_container = new System.Net.CookieContainer();
