1、编写获取文件名(全路径)子函数
/////param
///path:文件夹路径
///suffix:后缀格式, 如bmp,txt
///fileList:文件名存放
///isSubcatalog:true遍历子文件夹,否则不遍历
void
getFiles(string path, string suffix, ref Liststring> fileList, bool isSubcatalog) {   string filename;   DirectoryInfo dir = new DirectoryInfo(path);   FileInfo[] file = dir.GetFiles();   //DirectoryInfo[] dii = dir.GetDirectories();//如需遍历子文件夹时需要使用   foreach (FileInfo f in file)   {     filename = f.FullName;     if (filename.EndsWith(suffix))//判断文件后缀,并获取指定格式的文件全路径增添至fileList     {       fileList.Add(filename);     }   }   获取子文件夹内的文件列表,递归遍历
if(isSubcatalog)
{
   foreach (DirectoryInfo d in dii)    {    getFiles(d.FullName, fileList);    }
}
  return; }

2、在界面中放置一个button控件,单击按钮时弹出文件夹路径选择窗口,并调用getFiles子函数:

Liststring> imageFiles = new Liststring>();
private void btnSelectPath_Click(object sender, EventArgs e)
{
  FolderBrowserDialog dialog = new FolderBrowserDialog();
  dialog.Description = "Please choose image path.";
  DialogResult result = dialog.ShowDialog();
  if (result == System.Windows.Forms.DialogResult.Cancel)
  {
    return;
  }
  string folderPath = dialog.SelectedPath.Trim();
  DirectoryInfo theFolder = new DirectoryInfo(folderPath);
  if (theFolder.Exists)
  {
    getFiles(folderPath,"bmp", ref imageFiles, false);
    return; 
  }
}
