C#如何使图片随机循环 求解
C#如何使图片随机循环
代码如下：





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 The_Name
{
public partial class FormGame : Form
{

public FormGame()
{
InitializeComponent();
}

int shu;

private void buttonKaiShi_Click(object sender, EventArgs e)
{

shu = SuiJi();
timer1.Start();

}

public int SuiJi()
{
int sui = 0;
Random random = new Random();
sui = random.Next(1,8);
return sui;
}

private void timer1_Tick(object sender, EventArgs e)
{


switch (shu)
{
case 1:
pictureBox1.Top += 1;
if ( pictureBox1.Top >= pldi.Height)
{
pictureBox1.Top = pldi.Top;
}

break;
case 2:
pictureBox2.Top += 1;

if (pictureBox2.Top >= pldi.Height)
{
pictureBox2.Top = pldi.Top;

}
break;
case 3:
pictureBox3.Top += 1;
if (pictureBox3.Top >= pldi.Height)
{
pictureBox3.Top = pldi.Top;
}
break;
}


}
}
}

[最优解释]
Random random = new Random();
写在函数外面，作为成员变量。
