Use WebRequest.ContentType property. Some headers can be set using API properties only.
使用 WebRequest.ContentType 属性。某些标头只能使用 API 属性进行设置。
EDIT:
编辑：
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://www.androidlost.com/androidlost/greet");
request.ContentType = "text/x-gwt-rpc; charset=utf-8";

According to the MSDN documentation, HttpWebRequest.Header Property.
根据 MSDN 文档，HttpWebRequest.Header Property。
The Content-Type are modified using the ContentTypeproperty.
This requires that you cast the WebRequestto HttpWebRequest
使用ContentType属性修改内容类型。这就需要你投的WebRequest要HttpWebRequest
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://www.androidlost.com/androidlost/greet");
