[游戏开发]通过反射调用函数方法

已知函数名称，通过反射技术调用方法

public static T GetInvokeMethod<T>(string className, string methodName, object[] paras = null, bool isStatic = false)
{
    try
    {               
        Type type = Type.GetType(className);//类名也可以加入namespace，格式为"namespace.className"
        if (type == null) return default(T);
                      
        if (isStatic)
        {
            object ret = type.InvokeMember(methodName, BindingFlags.InvokeMethod | BindingFlags.Static | BindingFlags.Public, null, null, paras);
            if (ret == null)
            {
                return default(T);
            }
            else
            {
                return (T)ret;
            }
        }
        else
        {
            object obj = Activator.CreateInstance(type);
            if (obj == null) return default(T);

            MethodInfo method = null;
            if (paras != null && paras.Length > 0)
            {
                Type[] paratypes = new Type[paras.Length];
                for (int i = 0; i < paras.Length; i++)
                {
                    paratypes[i] = paras[i].GetType();
                }

                method = type.GetMethod(methodName, paratypes);
            }
            else
            {
                method = type.GetMethod(methodName);
            }

            return (T)method?.Invoke(obj, paras);
        }
    }
    catch
    {
        return default(T);
    }
}
