本文介绍了一个用于选择文件保存路径的C#类实现。通过创建一个目录选择器，用户可以通过弹出的对话框来选择文件夹。该实现利用了.NET Framework提供的组件，使得文件夹的选择过程变得简单直观。

添加引用system.design.dll

//选择文件的保存路径
DirBrowser olderBrowserDlg=new DirBrowser();

if (folderBrowserDlg.ShowDialog()==DialogResult.OK)
{
txtFilePath.Text = folderBrowserDlg.SelectedPath;
}

using System.Windows.Forms.Design;
using System.Windows.Forms;
using System;

//一般选择文件保存地址都用弹出对话框来进行选择
public class DirectorySelect : FolderNameEditor
{
private FolderBrowser fb = new FolderBrowser();
private string fDescription = "Choose Directory";
private string fReturnPath = String.Empty;

public string Description
{
set { fDescription = value; }
get { return fDescription; }
}

public string ReturnPath
{
get { return fReturnPath; }
}

public DirectorySelect()
{

}

private DialogResult RunDialog()
{
fb.Description = this.Description;
fb.StartLocation = FolderBrowserFolder.MyComputer;
fb.Style = FolderBrowserStyles.RestrictToSubfolders;
//|FolderBrowserStyles.RestrictToDomain;
return fb.ShowDialog();
}

public DialogResult ShowDialog()
{
DialogResult dRes = DialogResult.None;
dRes = RunDialog();
if (dRes == DialogResult.OK)
this.fReturnPath = fb.DirectoryPath;
else
this.fReturnPath = String.Empty;
return dRes;
}
}

//一般选择文件保存地址都用弹出对话框来进行选择
//调用
//DirBrowser myDirBrowser=new DirBrowser();
//if(myDirBrowser.ShowDialog()!=DialogResult.Cancel)
//MessageBox.Show(myDirBrowser.ReturnPath);

public class DirBrowser : FolderNameEditor
{
FolderBrowser fb = new FolderBrowser();
public string Description
{
set { _description = value; }
get { return _description; }
}

public string ReturnPath
{
get { return _returnPath; }
}

public DirBrowser() { }
public DialogResult ShowDialog()
{
fb.Description = _description;
fb.StartLocation = FolderBrowserFolder.MyComputer;
DialogResult r = fb.ShowDialog();
if (r == DialogResult.OK)
_returnPath = fb.DirectoryPath;
else
_returnPath = String.Empty;

return r;
}

//private string _description = "Choose Directory";
//private string _returnPath = String.Empty;
private string _description = "请选择文件夹";
private string _returnPath = String.Empty;
}
