C# 西里尔文柱头'；s值

下面是我的简单C代码：

所以，我试图将POST请求发送到Apache服务器并获得服务器的响应。我不需要任何额外的请求。问题是，我尝试运行此代码时出现异常：

System.ArgumentException was unhandled
  Message=Specified value has invalid Control characters.
Parameter name: value
  Source=System
  ParamName=value
  StackTrace:
       at System.Net.WebHeaderCollection.CheckBadChars(String name, Boolean isHeaderValue)
       at System.Net.WebHeaderCollection.Add(String name, String value)
       at Test.Program.Main(String[] args) in D:\Test\Test\Test\Program.cs:line 17

       at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state)
       at System.Threading.ThreadHelper.ThreadStart()
  InnerException: 

似乎我需要将标题值转换为ISO-8859-1编码。那么，我怎样才能让这个程序正常工作呢？对不起我的英语。我希望得到你的帮助。 提前谢谢

在我的情况下正确工作的示例请求：

POST / HTTP/1.1 s: АБВ12 username: user password: pass Content-Length: 0 Accept: */* User-Agent: Mozilla/4.0 (compatible; Win32; WinHttp.WinHttpRequest.5) Host: 127.0.0.1 Connection: Keep-Alive

---

args[0]包含任何西里尔字符。谢谢大家

您可以使用

Uri.EscapeDataString

对请求头中的非ASCII字符进行转义。下面的代码（使用一个简单的WCF服务来模拟接收方）展示了如何做到这一点。注意，您还需要在服务器端取消扫描头值（如下所示）

谢谢你的回复，卡洛斯！抱歉，但我并没有写我不能控制服务器端（例如，我写了本地地址）。问题是您的代码不起作用，但这是一个很好的尝试。请求已发送到服务器，但未被“识别”，因为它试图在数据库中查找“s”头值的值。我在VisualFoxPro中有一个程序可以正确地与该web服务器一起工作（请参阅问题更新中的适当请求示例）。所以它似乎使用特定的crarterset将其发送到服务器。 POST / HTTP/1.1 s: АБВ12 username: user password: pass Content-Length: 0 Accept: */* User-Agent: Mozilla/4.0 (compatible; Win32; WinHttp.WinHttpRequest.5) Host: 127.0.0.1 Connection: Keep-Alive

WinHttp.WinHttpRequest oHTTP = new WinHttp.WinHttpRequest();
oHTTP.Open("POST", "http://127.0.0.1:8888/");
oHTTP.SetRequestHeader("s", args[0]);
oHTTP.SetRequestHeader("username", "user");
oHTTP.SetRequestHeader("password", "pass");
oHTTP.Send();
