C#怎么让随机数字在timer属性Interval=100 的时候变一次!也就是1秒变十次？

不明白楼主的实际意思是什么~我猜测着写了这个代码~你看下
/// <summary>
/// 停止获取
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void button12_Click(object sender, EventArgs e)
{
timer1.Stop();
}
/// <summary>
/// 获取随机数
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void button11_Click_1(object sender, EventArgs e)
{
timer1.Start();
}

private void timer1_Tick(object sender, EventArgs e)
{
Random ran = new Random();
txtRandom.Text = ran.Next(100).ToString();
}

那你在timer的事件里生成随机数字啊

using System;
