c#编写循环播放文件夹下图片代码

如题所述

参考一下。。。

public partial class Form4 : Form
{
public Form4()
{
InitializeComponent();
}
//存放所有图片路径
List<string> picPathList = new List<string>();
protected override void OnLoad(EventArgs e)
{
//获取指定文件夹的所有文件
string[] paths = Directory.GetFiles(@"D:\photo\Camera");
foreach (var item in paths)
{
//获取文件后缀名
string extension = Path.GetExtension(item).ToLower();
if (extension == ".jpg" || extension == ".png" || extension == ".gif" || extension == ".bmp")
{
picPathList.Add(item);//添加到图片list中
}
}
if (picPathList.Count > 0) //如有图片
timer1.Start();
base.OnLoad(e);
}
private int picIndex = 0;
private void timer1_Tick(object sender, EventArgs e)
{
if (picIndex == picPathList.Count) //如果到了最后一个图片，从头开始
picIndex = 0;
this.pictureBox1.Image = Image.FromFile(picPathList[picIndex]);
picIndex++;
}
}
