本文介绍了如何使用C#中的FolderBrowserDialog和OpenFileDialog来让用户选择目录或文件。通过简单的步骤，可以实现获取用户选择的目录路径或文件名的功能。

//TextBox tbDir = new TextBox(); FolderBrowserDialog folderBrowserDialog1 = new FolderBrowserDialog(); folderBrowserDialog1.Description = "请选择保存输出图件的文件夹"; folderBrowserDialog1.ShowNewFolderButton = true; folderBrowserDialog1.RootFolder = Environment.SpecialFolder.MyComputer; //folderBrowserDialog1.RootFolder = Environment.SpecialFolder.Personal; DialogResult result = folderBrowserDialog1.ShowDialog(); if (result == DialogResult.OK) { string folderName = folderBrowserDialog1.SelectedPath; if (folderName != "") { //tbDir.Text = folderName; textBox1.Text = folderName; } }

private void button1_Click(object sender, EventArgs e)//使用FolderBrowserDialog打开目录 { FolderBrowserDialog folderBrowserDialog1 = new FolderBrowserDialog(); folderBrowserDialog1.RootFolder = Environment.SpecialFolder.MyComputer; folderBrowserDialog1.ShowNewFolderButton = true;//显示“新建文件夹”按钮 folderBrowserDialog1.RootFolder = Environment.SpecialFolder.Personal;//只能看到“我的文档” DialogResult result = folderBrowserDialog1.ShowDialog();//指定标示符,对话框的返回值 if (folderBrowserDialog1.ShowDialog() == DialogResult.OK) { textBox1.Text = folderBrowserDialog1.SelectedPath;//得到你选择的路径 } }

使用OpenFileDialog打开目录，获得选择的文件名字

private void button1_Click(object sender, EventArgs e) { OpenFileDialog openFileDialog1 = new OpenFileDialog(); openFileDialog1.FileName = Environment.SpecialFolder.MyComputer.ToString(); if (openFileDialog1.ShowDialog() == DialogResult.OK) { textBox1.Text = openFileDialog1.FileName; } }
