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 List<string> 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：
List<string> imageFiles = new List<string>();
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;
}
}
以上实例代码大家可以本机测试下，
