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; } }
