C# 有关泛型类继承

Posted on 2017年4月12日 by 平子

泛型的继承判断：

public static bool IsAssignableToGenericType(Type givenType, Type genericType)
        {
            var interfaceTypes = givenType.GetInterfaces();

            foreach (var it in interfaceTypes)
            {
                if (it.IsGenericType && it.GetGenericTypeDefinition() == genericType)
                    return true;
            }

            if (givenType.IsGenericType && givenType.GetGenericTypeDefinition() == genericType)
                return true;

            Type baseType = givenType.BaseType;
            if (baseType == null) return false;

            return IsAssignableToGenericType(baseType, genericType);
        }

public static bool IsAssignableToGenericType(Type givenType, Type genericType)

{

var interfaceTypes = givenType.GetInterfaces();

foreach (var it in interfaceTypes)

{

if (it.IsGenericType && it.GetGenericTypeDefinition() == genericType)

return true;

}

if (givenType.IsGenericType && givenType.GetGenericTypeDefinition() == genericType)

return true;

Type baseType = givenType.BaseType;

if (baseType == null) return false;

return IsAssignableToGenericType(baseType, genericType);

}

比如泛型类声明：

abstract public class BaseClass<T> where T : BaseClass<T>

1	abstract public class BaseClass<T> where T : BaseClass<T>
