c# - 如何将参数添加到 WebRequest 中？

Question

我需要从网络服务调用一个方法，所以我写了这段代码:

 private string urlPath = "http://xxx.xxx.xxx/manager/";
 string request = urlPath + "index.php/org/get_org_form";
 WebRequest webRequest = WebRequest.Create(request);
 webRequest.Method = "POST";
 webRequest.ContentType = "application/x-www-form-urlencoded";
 webRequest.
 webRequest.ContentLength = 0;
 WebResponse webResponse = webRequest.GetResponse();

但是这个方法需要一些参数，如下:

发布数据:

_username:'API USER',         // api authentication username

_password:'API PASSWORD',     // api authentication password

如何将这些参数添加到此 Webrequest 中？

提前致谢。

使用流向webrequest写入内容

string data = "username=<value>&password=<value>"; //replace <value>
byte[] dataStream = Encoding.UTF8.GetBytes(data);
private string urlPath = "http://xxx.xxx.xxx/manager/";
string request = urlPath + "index.php/org/get_org_form";
WebRequest webRequest = WebRequest.Create(request);
webRequest.Method = "POST";
webRequest.ContentType = "application/x-www-form-urlencoded";
webRequest.ContentLength = dataStream.Length;  
Stream newStream=webRequest.GetRequestStream();
// Send the data.
newStream.Write(dataStream,0,dataStream.Length);
newStream.Close();
WebResponse webResponse = webRequest.GetResponse();
