如何在C#中使用Java风格的throws关键字？

using System;

public class MyException : Exception
{
    public MyException(string message) : base(message)
    {
    }
}

public class MyClass
{
    public void MyMethod()
    {
        throw new MyException("This is a custom exception.");
    }
}

public class Program
{
    public static void Main()
    {
        try
        {
            MyClass myObject = new MyClass();
            myObject.MyMethod();
        }
        catch (MyException ex)
        {
            Console.WriteLine("Caught custom exception: " + ex.Message);
        }
        catch (Exception ex)
        {
            Console.WriteLine("Caught general exception: " + ex.Message);
        }
    }
}
