c# - 如何在运行时获取静态类的方法名？

Question

如何获取像 Math 这样的静态类中的所有方法名？

输出应类似于以下内容:

Sin
Cos
Round
...

Answer 1

试试这个:

    MethodInfo[] methodInfos = typeof(Math).GetMethods(BindingFlags.Public | BindingFlags.Static);
    foreach (MethodInfo methodInfo in methodInfos)
    {
        Console.WriteLine(methodInfo.Name);
    }

此外，如果您还需要知道所有参数，请尝试类似

    private static void Main()
    {
        MethodInfo[] methodInfos = typeof(Math).GetMethods(BindingFlags.Public | BindingFlags.Static);
        foreach (MethodInfo methodInfo in methodInfos)
        {
            Console.WriteLine(String.Format("{0} with following parameters", methodInfo.Name));
            ParameterInfo[] parameters = methodInfo.GetParameters();
            foreach (ParameterInfo parameter in parameters)
            {
                Console.WriteLine("Name : {0}, Type : {1}", parameter.Name, parameter.ParameterType.FullName);
            }

            Console.WriteLine("--------------");
        }
    }

输出:
