实现你想要的最好的方法是创建你自己的基于wpf的控件，或者使用别人做的控件 为什么?因为在WPF应用程序中使用winforms对话框会有明显的性能影响(出于某种原因) 我推荐这个项目 https://opendialog.codeplex.com/ 或Nuget:

PM> Install-Package OpenDialog

它是非常MVVM友好的，它没有包装winforms对话框

对于目录对话框获取目录路径，首先添加引用System.Windows。表单，然后解析，然后把这个代码放在按钮点击。

    var dialog = new FolderBrowserDialog();
    dialog.ShowDialog();
    folderpathTB.Text = dialog.SelectedPath;

(folderpathTB是文本框的名字，我想把文件夹路径，或者你可以把它分配给一个字符串变量也就是)

    string folder = dialog.SelectedPath;

如果你想获得文件名/路径，只需在按钮单击上这样做

    FileDialog fileDialog = new OpenFileDialog();
    fileDialog.ShowDialog();
    folderpathTB.Text = fileDialog.FileName;

(folderpathTB是文本框的名字，我想把文件路径，或者你可以把它分配给一个字符串变量太)

注意:对于文件夹对话框，必须将System.Windows.Forms.dll添加到项目中，否则它将无法工作。

Ookii对话框包括一个选择文件夹(而不是文件)的对话框:

https://github.com/ookii-dialogs

我建议，在黄金套餐中加入:

  Install-Package OpenDialog

那么使用它的方法是:

    Gat.Controls.OpenDialogView openDialog = new Gat.Controls.OpenDialogView();
    Gat.Controls.OpenDialogViewModel vm = (Gat.Controls.OpenDialogViewModel)openDialog.DataContext;
    vm.IsDirectoryChooser = true;
    vm.Show();

    WPFLabel.Text = vm.SelectedFilePath.ToString();

以下是文档: http://opendialog.codeplex.com/documentation

适用于文件，文件过滤器，文件夹等

你可以像这样在WPF中使用smth。我已经创建了示例方法。 下面的检查。

public string getFolderPath()
{
           // Create OpenFileDialog 
           Microsoft.Win32.OpenFileDialog dlg = new Microsoft.Win32.OpenFileDialog();

           OpenFileDialog openFileDialog = new OpenFileDialog();
           openFileDialog.Multiselect = false;

           openFileDialog.InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
           if (openFileDialog.ShowDialog() == true)
           {
               System.IO.FileInfo fInfo = new System.IO.FileInfo(openFileDialog.FileName);
               return fInfo.DirectoryName;
           }
           return null;           
       }
