Question

我试图将java代码转换为cSharp .I结构如何编码数据，所以请帮我怎么做..

我试图直接传递值而不进行编码，然后我得到错误

The remote server returned an error: (400) Bad Request.

如果我删除了标题，那么错误就不会到来，我在网站上放置了断点，执行顺序没有在断点处停止

这是我的java代码

packagename=encodeData("some value");
username=encodeData("some value");
password=encodeData("some value");

hc= new DefaultHttpClient();
get= new HttpGet("http://techpalle.com/skillgun_App.svc/mobile/papers/"+chap_id+"/app");
get.setHeader(PaperActivity.this.getString(R.string.username),username);
get.setHeader(PaperActivity.this.getString(R.string.password),password);
get.setHeader(PaperActivity.this.getString(R.string.packagename),packagename);

转换后的csharp代码

string username=null;
string password=null;
string packagename=null;

HttpWebRequest wr = (HttpWebRequest)WebRequest.Create("http://localhost:2850/TechpalleNew/Skillgun_App.svc/mobile/chapters/" + "16" + "/app");
wr.Headers["username"] = "username";
wr.Headers["password"] = "password";
wr.Headers["packagename"] = "packagename";
WebResponse resp = wr.GetResponse();
StreamReader read = new StreamReader(resp.GetResponseStream());
string res = read.ReadToEnd();

对于html编码（您没有指定其他编码），请使用静态方法
