Question

有一个美好的一天需要帮助从这里我有安全管理器类继承SendSecurityFilter类WSE3但它在构建它时返回错误genarate这个错误请帮我解决这个有关这个类详细信息。谢谢

错误1'Microsoft.Web.Services3.Security.SendSecurityFilter'不包含带0参数的构造函数

公共类SecurityManager：SendSecurityFilter { public override void SecureMessage（SoapEnvelope信封，安全性安全性） {

 // Get an X.509 certificate for signing the SOAP message.

        }

        // Add the X.509 certificate to the header.
        security.Tokens.Add(signatureToken);

        // Specify that the SOAP message is signed using this X.509
        // certifcate.

您收到此错误的原因是base SendSecurityFilter类没有带0参数的默认构造函数。并且您没有为SecurityManager类实现任何构造函数，因此应该生成默认构造函数：

10.10.4 Default constructors

如果类不包含实例构造函数声明，则为默认值   实例构造函数自动提供。那个默认   构造函数只需调用direct的无参数构造函数   基类。

但是SendSecurityFilter没有从SecurityManager类调用的无参数构造函数！

要修复此错误，您应该实现其中一个构造函数或两者：

//replace "public" with suitable modififier
public SecurityManager(string serviceActor, bool isClient) : base(serviceActor, isClient)
{
}

//replace "public" with suitable modififier
public SecurityManager(string serviceActor, bool isClient, string clientActor) : base(serviceActor, isClient, clientActor)
{
}

使用X.509证书错误加密SOAP消息
