C#示范结构体的语法和用法

本示例演示结构的语法和用法。它还介绍了类与结构之间的重大差异

//&nbspstruct1.cs

using System;
struct SimpleStruct
{
    private int xval;
    public int X
    {
        get 
        {
            return xval;
        }
        set 
        {
            if (value < 100)
                xval = value;
        }
    }
    public void DisplayX()
    {
        Console.WriteLine("The stored value is: {0}", xval);
    }
}
class TestClass
{
    public static void Main()
    {
        SimpleStruct ss = new SimpleStruct();
        ss.X = 5;
        ss.DisplayX();
    }
}

//&nbspstruct2.cs

using System;
class TheClass
{
    public int x;
}
struct TheStruct
{
    public int x;
}
class TestClass
{
    public static void structtaker(TheStruct s)
    {
        s.x = 5;
    }
    public static void classtaker(TheClass c)
    {
        c.x = 5;
    }
    public static void Main()
    {
        TheStruct a = new TheStruct();
        TheClass b = new TheClass();
        a.x = 1;
        b.x = 1;
        structtaker(a);
        classtaker(b);
        Console.WriteLine("a.x = {0}", a.x);
        Console.WriteLine("b.x = {0}", b.x);
    }
}
