C#中 openfiledialog 和 FolderBrowserDialog 的使用

1. openfiledialog的使用

//open the dialog

private void butn_open_Click(object sender, EventArgs e)

{

openFileDialog1.InitialDirectory = "D:\\"; // 这里是初始的路径名

openFileDialog1.Filter = "类文件|*.cs|所有文件|*.*"; //设置打开文件的类型

openFileDialog1.RestoreDirectory = true; //设置是否还原当前目录

openFileDialog1.FilterIndex = 0; //设置打开文件类型的索引

string path = ""; //用于保存打开文件的路径

if (openFileDialog1.ShowDialog() == System.Windows.Forms.DialogResult.OK)

{

path = openFileDialog1.FileName;

MessageBox.Show(path); //显示该路径名

}

}

2.FolderBrowserDialog 的使用

//open the dialog

private void butn_open_Click(object sender, EventArgs e)

{

folderBrowserDialog1.RootFolder = Environment.SpecialFolder.Desktop; // 这里是设置初始的路径名

string path = ""; //保存选择文件夹的名称

if (folderBrowserDialog1.ShowDialog() == System.Windows.Forms.DialogResult.OK)

{

path = folderBrowserDialog1.SelectedPath;

MessageBox.Show(path); //显示该路径名

}

}
