C#文字滚动

[askjhx]

做项目的时候 我想用一个lable控件作出一个从左向右的滚动效果，当它到了最左边的时候又会自动的回到右边 然后就是一直的滚动 从右边到左边一直循环这滚动 请问一下 我该怎么样去做它
还忘各位不吝赐教.... 谢谢了 （最好能给点代码的提示）

[修改一下昵称]

private void Form1_Load(object sender, EventArgs e)
        {
            this.label1.Location = new Point(0, 0);
        }
         int xPox = 0;
        bool ist = true;
        private void timer1_Tick(object sender, EventArgs e)
        {
            this.label1.Location = new Point(xPox,this.label1.Location.Y);

            if (xPox == this.Width-this.label1.Size.Width)
                ist = false;
            if(xPox==0)
                ist = true;
            if (ist)
                xPox++;
            else
                xPox--;
        }

这个小功能如何实现?[label上的文字从右往左滚动显示]

二楼的 你的代码 很不错 我要的就是这样的 但是我看了半天没能看懂.... 如果可以的话 希望你帮帮写点注释 好不好

还有 我想让它只从右往左 不要让它在左边 就直接被弹了回来到右边 希望你能加点注释让我能好理解点 谢谢了

一楼的 写错了 不好意思.... 是一楼的那段源代码...

支持1楼的

[松林迷途]

路过 学知识来了。

[zhuxishanren]

我得在这好好学学。

[ye_jw]

一楼的似乎实现不了的……
试试这个：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace 欢迎条
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void Form1_Load(object sender, EventArgs e)
{
this.timer1.Interval = 10;
this.timer1.Enabled = true;
//this.WindowState = FormWindowState.Maximized;
}
private void timer1_Tick(object sender, EventArgs e)
{
label1.Left = label1.Left - 2;
if (label1.Right<0)
{
label1.Left = this.Width;
}
}

private void button1_Click(object sender, EventArgs e)
{
this.Close();
}
}
}

[ye_jw]

抱歉了，一楼的是可以的，实现的是字体向左向右移动的

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

}


private void Form1_Load(object sender, EventArgs e)

{

this.timer1.Interval = 1;

this.timer1.Enabled = true;

//this.WindowState = FormWindowState.Maximized;

}

bool i = true;

int xPox;

private void timer1_Tick(object sender, EventArgs e)

{

this.label1.Location = new Point(xPox, this.label1.Location.Y);

if (xPox > this.Width - this.label1.Size.Width+label1.Width)//字幕到了最右边
i = false;

if (xPox < 0-label1.Width)//字幕到了最左边

i = true;

if (i)

xPox+=5;//右走

else

xPox-=5;//左走


}

private void label1_Click(object sender, EventArgs e)

{

this.Close();

}

}

LBG.Text = LBG.Text.Substring(1) + LBG.Text[0];
这个是最好用的
LBG是标签
不明白的找我
还有啊，别忘记TMG.Stop();启动记时器

[lqliang125]

label1.Left = label1.Left - 2;
if (label1.Right < 0)
{
label1.Left = this.Width;
}
