从堆栈中的类获取泛型参数(Getting generic arguments from a class in the stack)

 我有一个名为Repository的泛型类。 该类有一个函数，通过使用不同的泛型参数初始化Repository类的新实例来“调用自身”。 这个“递归”可以继续 - 所以为了避免StackOverflowException，我需要检查堆栈中是否存在一个从Repository类调用的具有相同泛型参数的方法。 这是我的代码： 
 
    StackTrace stack = new StackTrace();
    StackFrame[] frames = stack.GetFrames();

    foreach (StackFrame frame in frames)
    {
        Type callingMethodClassType = frame.GetMethod().DeclaringType;
        if (callingMethodClassType.IsGenericType)
        {
            // BUG HERE in getting generic arguments of the class in stack
            Type genericType = callingMethodClassType.GetGenericArguments()[0];
            if (genericType.Equals(entityType))
            {
                wasAlready = true;
                break;
            }
        }
    }
 
 泛型类型始终返回为T而不是正确的类型，如“User”或“Employee”（例如）。 我无法比较类型的名称，因为T没有名称。 

I have a generic class called Repository. This class has a function that "calls itself" by initializing a new instance of the Repository class with a different generic argument. This "recursion" can go on - so to avoid StackOverflowException, i need to check if there is in the stack, a method called from the Repository class with the same generic argument. here is my code:
 
    StackTrace stack = new StackTrace();
    StackFrame[] frames = stack.GetFrames();

    foreach (StackFrame frame in frames)
    {
        Type callingMethodClassType = frame.GetMethod().DeclaringType;
        if (callingMethodClassType.IsGenericType)
        {
            // BUG HERE in getting generic arguments of the class in stack
            Type genericType = callingMethodClassType.GetGenericArguments()[0];
            if (genericType.Equals(entityType))
            {
                wasAlready = true;
                break;
            }
        }
    }
 
the generic type always returns as T and not the correct type like "User" or "Employee" (for example). I can't compare the names of the types because T does not have a name.
