6.10.1.Use ref for a struct parameter
using System;

public struct MyStruct
{
    public int val;
}

public class MainClass
{
    static void Main() {
        MyStruct myValue = new MyStruct();
        myValue.val = 10;

        PassByValuemyValue );
        Console.WriteLine"Result of PassByValue: myValue.val = {0}", myValue.val );

        PassByRefref myValue );
        Console.WriteLine"Result of PassByRef: myValue.val = {0}", myValue.val );
    }

    static void PassByValueMyStruct myValue ) {
        myValue.val = 50;
    }

    static void PassByRefref MyStruct myValue ) {
        myValue.val = 42;
    }
}
Result of PassByValue: myValue.val = 10
Result of PassByRef: myValue.val = 42
