C# 如何向asp.net中的context.response添加新标题

我对asp.net很陌生。我正在构建一个现有的项目，其中来自js文件的用户名和密码被加密，并且对.aspx.cs文件进行ajax函数调用。这个ashx.cs文件对它们进行解密，然后将它们插入到数据库表中。现在我想加入一个名为“域”的新字段，但我不知道如何为它创建一个头，以便将它从js传递到ashx.cs文件。我的问题可能很傻，但我已经为此挣扎了一段时间，非常感谢您的帮助。我尝试对域使用context.Response.AddHeader，但我不知道应该向其中传递什么值

“RUN”和“RUP”似乎已经在某个地方创建了，我无法找到它们来遵循相同的域标题

js文件：

function Register() {

    if (ValidateRegisterWindow()) {

        var URL = "SecureChatServer.ashx";
        if (URL == null) { alert("Request URL is Empty"); }
        else {
            username = Encrypt(document.getElementById('NewUserName').value, EncryptionKey);
            password = Encrypt(document.getElementById('NewPassword').value, EncryptionKey);
            domain = Encrypt(document.getElementById('NewDomain').value, EncryptionKey);

            AjaxRequest(ProcessRegisterResponse, URL, "POST", '', '', { RequestCode: 'SC006', RUN: username, RUP: password}); //how to pass domain here??
        }
    }

}


function ProcessRegisterResponse() {

    var ResponseStatus = GetHeader(ResponseHeaderJSON, 'ResponseStatus');
    if (ResponseStatus == "RS-OK") {

        ShowAlertMessage("Registration Sucessful", "", "User Registered and Logged in Sucessfully");
        CurrentUser = document.getElementById('NewUserName').value;
        LoginEvents(CurrentUser, true);
        ClearRegisterWindow();


    }
    else if (ResponseStatus == "RS-Failed") {

        ShowErrorBox("Registration Error", "This username cannot be registered ,please try a different username");

    }
    else {

        ShowErrorBox("Unknown Error :Code-01 " + ResponseStatus, "Request cannot be processed ,please try again.");

    }
}

ashx.cs文件：

  #region Handle Add New User Request
            case "SC006":  //indicates request to add new user
                {
                    string UserName, Password;
                    UserName = Decrypt(context.Request.Headers["RUN"], EncryptionKey);
                    Password = Decrypt(context.Request.Headers["RUP"], EncryptionKey);
                    Users newuser = new Users();

                    try
                    {
                        if (newuser.AddUser(UserName, Password, SessionID, UserIPAddress))
                        {
                            context.Response.AddHeader("CustomHeaderJSON", "ResponseStatus:'RS-OK'");
                        }
                        else
                        {
                            context.Response.AddHeader("CustomHeaderJSON", "ResponseStatus:'RS-Failed'");
                        }
                    }
                    catch (Exception e)
                    {
                        Debug.WriteLine("Failed Request SC006 : " + e.ToString());
                        context.Response.AddHeader("CustomHeaderJSON", "ResponseStatus:'RS-Exception'");

                    }
                }
                break;

            #endregion

您可以使用此代码轻松地添加标题

context.Response.Headers.Add（“此处为您的标题”）

.NET framework 3.5是的，我试过了，但是我不知道要为NameValueCollection传递什么值。你能再解释一下吗？谢谢，我创建了一个新的NameValueCollection并传递了它。它起作用了System.Collections.Specialized.NameValueCollection=new System.Collections.Specialized.NameValueCollection（）；context.Response.Headers.Add（RUT）`
