WPF中使用文件浏览对话框的几种方式-阿里云开发者社区

WPF本身并没有为我们提供文件浏览的控件, 也不能直接使用Forms中的控件,而文件浏览对话框又是我们最常用的控件之一. 下面是我实现的方式

方式1：使用win32控件OpenFileDialog


      Microsoft.Win32.OpenFileDialog ofd =

new


      Microsoft.Win32.OpenFileDialog();


      ofd.DefaultExt =


      ".xml"


      ofd.Filter =


      "xml file|*.xml"

if


      (ofd.ShowDialog() ==


      true


      //此处做你想做的事 ...=ofd.FileName;

方式2：使用Forms中的OpenFileDialog控件

WPF中是不能直接使用Forms中的控件的,否则会提示找不到Forms名字控件. 如果你仍然要用, 答案便是添加.net 引用reference

之后就可以像下面一样正常使用Forms中的控件了


      System.Windows.Forms.OpenFileDialog openFileDialog1 =

new


      System.Windows.Forms.OpenFileDialog();


      openFileDialog1.InitialDirectory =


      "c:\\"


      openFileDialog1.Filter =


      "txt files (*.txt)|*.txt|All files (*.*)|*.*"


      openFileDialog1.FilterIndex = 2;


      openFileDialog1.RestoreDirectory =


      true

if


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


      //此处做你想做的事 ...=openFileDialog1.FileName;


      System.Windows.Forms.FolderBrowserDialog folderBrowserDialog =

new


      System.Windows.Forms.FolderBrowserDialog();


      System.Windows.Forms.DialogResult result = folderBrowserDialog.ShowDialog();

if


      (result == System.Windows.Forms.DialogResult.OK)


      tb_FolderPath.Text = folderBrowserDialog.SelectedPath;


      [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Auto)]

      OpenFileName ofn =

      OpenFileName();


      ofn.structSize = Marshal.SizeOf(ofn);


      ofn.filter =


      "Project files\0*.xml"


      ofn.file =

new


      string

new


      char


      [256]);


      ofn.maxFile = ofn.file.Length;


      ofn.fileTitle =

new


      string

new


      char


      [64]);


      ofn.maxFileTitle = ofn.fileTitle.Length;


      ofn.initialDir =


      "C:\\"


      ofn.title =


      "Open Project"


      ofn.defExt =


      "xml"


      ofn.structSize = Marshal.SizeOf(ofn);

if


      (LibWrap.GetOpenFileName(ofn))


      //此处做你想做的事 ...=ofn.file;

一般来说关于WPF使用3D的例子，都是下面的流程： 1.美工用3DMAX做好模型，生成一个obj文件 2.程序然后打开Blender，将obj拖动到Blender中，生成xaml代码但是这样做会有至少两个问题： 1. 维护麻烦，因为一旦模型修改，你需要重复上面的步骤，至少要修改xaml的代码。
