c#
1.遍歷目錄 查找圖片
2.在 pictureBox 循環播放
public void PlayThread()//CMD_UpdateBtnStatus cmd
{

string suffix = "*.jpg";
List<String> list = Utility.TraverseDirector(videoFramePath, false, true, suffix);
if (list.Count == 0)
{
return;
}
UInt32 count = (UInt32)list.Count;
while (_ImagePlayThreadLoop)
{
for (UInt32 index = 0; index < count; index++)
{
//this.Invoke((EventHandler)(delegate //數據返回錯誤
//{
//Tab4_UVC_pictureBox.Load(list[(Int32)index]); //同步方式 必須要delegate 方式更新(手動添加 異步方式)
//不能在這里sleep 會卡死UI線程
//}));
//直接用異步方式,更新圖片數據
//文件不存在就continue;
if (!File.Exists(list[(Int32)index])) continue;
