WinForm 文件夹和文件选择对话框

1.文件选择对话框，选择多个文件并绑定ListBox    private void SelectMultiFile()
     {
             OpenFileDialog fileDialog = new OpenFileDialog();
             fileDialog.Multiselect = true; //可以选择多个文件
             fileDialog.Filter = "GeoMap图件|*.gdb|所有文件|*.*";
             if (fileDialog.ShowDialog() == DialogResult.OK)
             {
                 ArrayList fileList = new ArrayList();                 foreach (string file in fileDialog.FileNames)
                 {
                     FileInfo info = new FileInfo(file.Substring(file.LastIndexOf("\\") + 1), file);
                     fileList.Add(info);
                 }
                 listBoxSelectedFile.DataSource = fileList;
                 listBoxSelectedFile.DisplayMember = "FileName";
                 listBoxSelectedFile.ValueMember = "FileFullName";
             }
      } public class FileInfo
 {
     private string _FileName;
     private string _FileFullName;     public FileInfo(string fileName, string fileFullName)
     {
         _FileName = fileName;
         _FileFullName = fileFullName;
     }     public string FileName
     {
         get { return _FileName; }
         set { _FileName = value; }
     }     public string FileFullName
     {
         get { return _FileFullName; }
         set { _FileFullName = value; }
     }
 } 2.文件夹选择对话框要实现文件夹对话框，需要继承FolderNameEditor类，创建FolderBrowser类的实例。
 引用System.Design.dll，using System.Windows.Forms.Design，代码如下：
 public class FolderDialog : FolderNameEditor
     {
         FolderBrowser fDialog = new FolderBrowser();         public FolderDialog()
         {
         }         public DialogResult DisplayDialog()
         {
             return DisplayDialog("请选择保存位置");
         }         public DialogResult DisplayDialog(string description)
         {
             fDialog.Description = description;
             return fDialog.ShowDialog();
         }         public string Path
         {
             get { return fDialog.DirectoryPath; }
         }         ~FolderDialog() { fDialog.Dispose(); }
     } 
 调用：
             string savePath="";
             FolderDialog folder = new FolderDialog();
             if (folder.DisplayDialog() == DialogResult.OK)
             {
                 savePath = folder.Path;
             }
             else
             {
                 return;
             }
