使用矩阵方式进行文件夹的选择即类似OpenFileDialog

Microsoft.WindowsAPICodePack.dll

Microsoft.WindowsAPICodePack.Shell.dll

2、代码

var commonOpenFileDialog = new CommonOpenFileDialog();
commonOpenFileDialog.IsFolderPicker = true;	//设置为true为选择文件夹，设置为false为选择文件
commonOpenFileDialog.Title = "选择文件夹";
commonOpenFileDialog.InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.ProgramFiles);
var result = commonOpenFileDialog.ShowDialog();
if (result == CommonFileDialogResult.Ok)
{
string str = commonOpenFileDialog.FileName;
}
