WPF FolderBrowserDialog控件的使用

FolderBrowserDialog是Winform中的控件，可以用于选择指定的文件夹路径；

一、首先需在项目中手动添加引用：System.Windows.Forms；

二、在项目中添加类COldWindow.cs；

public class OldWindow : System.Windows.Forms.IWin32Window
    {
        IntPtr _handle;
        public OldWindow(IntPtr handle)
        {
            _handle = handle;
        }
        #region IWin32Window Members
        IntPtr System.Windows.Forms.IWin32Window.Handle
        {
            get { return _handle; }
        }
        #endregion
    }

三、具体的使用方法：

System.Windows.Forms.FolderBrowserDialog objFBD = new System.Windows.Forms.FolderBrowserDialog();
objFBD.ShowNewFolderButton = false;
System.Windows.Interop.HwndSource source = PresentationSource.FromVisual(this) as System.Windows.Interop.HwndSource;
System.Windows.Forms.IWin32Window win = new OldWindow(source.Handle);

objFBD.Description = "导出到...";

if (objFBD.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
     //处理函数
}
