您收到此错误的原因是基本SendSecurityFilter类没有采用 0 个参数的默认构造函数。而且您没有为您的 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 默认构造函数

如果类不包含实例构造函数声明，则会自动提供默认实例构造函数。该默认构造函数只是调用直接基类的无参数构造函数。

但是 SendSecurityFilter 没有可以从您的 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或两个构造函数：

//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)
{
}
