怎么在winform中让一个label左右循环飘动
我想在窗体上飘一行文字，而且是从左到右，但是文字会飘出窗体外边看不见了，
我需要飘出去的那部分从右边在接着飘出来可以吗？

label
写个循环么。
用timer，每隔一段时间left-1.。。
判断left<0
在把它移动到最右边
[解决办法]
你判断一下它的location，如果跑出去了就给它重置到左边

            InitializeComponent();
        }


        private void Form1_Load(object sender, EventArgs e)
        {        
        }

        private void button1_Click(object sender, EventArgs e)
        {
            if (!started)
            {
                started = true;
                timer1.Start();
                button1.Text = "停止";

        private void timer1_Tick_1(object sender, EventArgs e)
        {
            if (label1.Left <= 0)
                direction = 1;
            if (label1.Right >= this.Width)
                direction = -1;
            label1.Left += direction * 2;

        }

        private void button2_Click(object sender, EventArgs e)
        {
            Form2 f2= new Form2();
            f2.Owner = this;
            f2.ShowDialog();

        }
     

    }
}

//form2

using System;
using System.Collections.Generic;

using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace WindowsApplication3
{
    public partial class Form2 : Form

        public Form2()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            if (radioButton1.Checked)
                ((Form1)this.Owner).direction = -1;
            else
                ((Form1)this.Owner).direction = 1;
            this.Close();

        }

    }
}
