Question

C#新手，想实现一个窗口不断移动程序（下面的代码），但是运行出来，窗口一直未移动过，这是为什么？求教

System.Timers.Timer MyTimer = new System.Timers.Timer();
private void Form1_Load(object sender, EventArgs e)
{
MyTimer.Interval = 1000;
MyTimer.Elapsed += new ElapsedEventHandler(MyTimer_Elapsed);
MyTimer.Start();
}

private int x = 100, y = 100;
private void MyTimer_Elapsed(object sender, ElapsedEventArgs e)
{
this.Location = new Point(x++, y++);
}

Answer 1

//因为Timers.Timer在一个新的线程运行，直接访问form1会报错的。

        System.Timers.Timer MyTimer = new System.Timers.Timer();
        private void Form1_Load(object sender, EventArgs e)
        {
            MyTimer.SynchronizingObject = this;
            MyTimer.Interval = 1000;
            MyTimer.Elapsed += new ElapsedEventHandler(MyTimer_Elapsed);
            MyTimer.Start();
        }
        private int x = 100, y = 100;
        private void MyTimer_Elapsed(object sender, ElapsedEventArgs e)
        {
            ((Form1)MyTimer.SynchronizingObject).Location = new Point(x++, y++);
        }

Answer 2

public delegate void formWalk();
public formWalk myDelegate;
System.Timers.Timer MyTimer = new System.Timers.Timer();

public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
MyTimer.Interval = 1000;
MyTimer.Elapsed += new ElapsedEventHandler(MyTimer_Elapsed);
MyTimer.Start();
}
private void MyTimer_Elapsed(object sender, ElapsedEventArgs e)
{
myDelegate = new formWalk(formgo);
this.Invoke(myDelegate);
}

private int x = 100, y = 100;
private void formgo()
{
this.Location = new Point(x++, y++);
}
多线程调用问题，你用invoke去调用主窗体，或者主窗体控件

Answer 3

MyTimer.Start();改成

MyTimer.Enabled=true;试试

Answer 4

System.Timers.Timer 看MyTimer看 = new System.Timers.Timer();
private void Form1_Load(object sender, EventArgs e)
{
MyTimer.Interval = 1000;
MyTimer.Elapsed += new ElapsedEventHandler(MyTimer_Elapsed);
MyTimer.Start();
}

private int x = 100, y = 100;
private void MyTimer_Elapsed(object sender, ElapsedEventArgs e)
{
this.Location = new Point(x++, y++);
}
这里
