求助字幕的移动
private void button1_Click(object sender, EventArgs e){
if (button1.Text == "开始")
{
button1.Text = "停止";
timer1.Enabled =true ;
}
else
{
button1.Text = "开始";
timer1.Enabled =false ;
}
}
private void timer1_Tick(object sender, EventArgs e)
{
int a = label1.Location.X-10;
int b = label1.Location.Y;
if (a<-label1.Width )
a=this .Width ;
label1.Location = new Point(a, b);
}
}
为什么还是不能移动字幕呢?是不是要设置label的属性呢? --------------------编程问答-------------------- private void button2_Click(object sender, EventArgs e)
{
if (this.button2.Text == "开始")
{
this.button2.Text = "结束";
this.timer1.Enabled = true;
}
else
{
this.button2.Text = "开始";
this.timer1.Enabled = false;
}
}
private void timer1_Tick(object sender, EventArgs e)
{
int x = this.label1.Location.X - 10;
int y = this.label1.Location.Y;
if (x <= this.label1.Width)
{
x = this.Width;
}
this.label1.Location = new Point(x,y);

--------------------编程问答-------------------- 完整的代码:
int a = label1.Location.X - 10;
int b = label1.Location.Y;
if (a < -label1.Width)
a = this.Width;
this.Invoke(new Action(() =>
{
label1.Location = new Point(a, b);
}));
--------------------编程问答-------------------- System.Timers.Timer timer = new System.Timers.Timer(100);
System.Timers.Timer timer = new System.Timers.Timer(100);
public Form1()
{
InitializeComponent();
timer.Elapsed += timer_Elapsed;
}
private void button1_Click(object sender, EventArgs e)
{
if (button1.Text == "开始")
{
button1.Text = "停止";
timer.Enabled = true;
}

{
button1.Text = "开始";
timer.Enabled = false;

}
void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)

if (a < -label1.Width)
a = this.Width;
this.Invoke(new Action(() =>

这句是不是放在Using后面呢?
放在using后面的话会出错。。
注释掉这句还是不行,字幕动不了 --------------------编程问答--------------------
System.Timers.Timer timer = new System.Timers.Timer(100);

怎么会放到using后面……
难道你连基本的C#语法还没了解?
这是Form的一个字段,放在class内部就行了…… --------------------编程问答--------------------
呵呵 我是刚开始学的,还有很多不懂得的还要请教诸位哦!
这句放在放在class内部也不行哦!
补充:.NET技术 , C#
