WPF选择文件和文件夹对话框

Posted 2021-01-28 xinyf

WPF提供了选择文件对话框，但并没有提供选择文件夹的对话框。

OpenFileDialog类存在于PresentationFramework.dll程序集。

 1 public string SelectFileWpf()
 2         {
 3             var openFileDialog = new Microsoft.Win32.OpenFileDialog()
 4             {
 5                 Filter = "Text documents (.txt)|*.txt|All files (*.*)|*.*"
 6             };
 7             var result = openFileDialog.ShowDialog();
 8             if (result == true)
 9             {
10                 return openFileDialog.FileName;
11             }
12             else
13             {
14                 return null;
15             }
16         }

 

下面需要添加System.Windows.Forms.dll

using System.Windows.Forms;

1  public string SelectPath() //弹出一个选择目录的对话框
2         {
3             FolderBrowserDialog path = new FolderBrowserDialog();
4             path.ShowDialog();
5             return path.SelectedPath;
6         }

 

选择文件

1  public string SelectFile() //弹出一个选择文件的对话框
2         {
3             OpenFileDialog file = new OpenFileDialog();
4             file.ShowDialog();
5             return file.SafeFileName;
6         }
