检查一个类是否派生自一个泛型类

试试这个代码

static bool IsSubclassOfRawGeneric(Type generic, Type toCheck) {    while (toCheck != null && toCheck != typeof(object)) {        var cur = toCheck.IsGenericType ? toCheck.GetGenericTypeDefinition() : toCheck;        if (generic == cur) { return true;        }        toCheck = toCheck.baseType;    }    return false;}
