Response.Write（ 连接到URL： + targetUrl + < br>）;
// 从文件中读取输入XML
StringBuilder sb = new StringBuilder （）;

// < span class =code-comment> String inputXml;

// using（StreamReader inputQueryReader = new StreamReader（@C：\ Users\Pramod\Desktop\PageID.xml））

Response.Write（ 输入xml值： + sb.ToString（）+ < br>）;



// 编码发布数据并设置请求注意：输入xml传递一个名为NETCONNECT_TRANSACTION的参数'



sb.Append（ p8admin，mits123
