对磁盘系统的操作，读取网页信息

直接操作磁盘，但是是否有权限问题没测试过
                           //引用System.Management.dll
                           //获取C盘的磁盘信息，去掉Where之后的获取所有逻辑磁盘信息
   ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT
* FROM Win32_LogicalDisk Where Name='C:'");
   
   foreach(ManagementObject disk in searcher.Get())
   {
    Console.WriteLine( " {0} - Size : {1},FreeSize: {2}",
disk["Name"],disk["Size"],disk["FreeSpace"]);
    
   }
另读其他网页的代码方法如下



public static string GetContent(string PageUrl)
  {
   try
   {
    WebClient wc = new WebClient();
    wc.Credentials = CredentialCache.DefaultCredentials;
    byte[] pageData=wc.DownloadData(PageUrl);
    wc.Dispose();
    return Encoding.Default.GetString(pageData);
    
   }
   catch
   {
    return "error";
   }   
  }
