如何在Environment.SpecialFolder中使用FolderBrowserDialog? [英] How do I use a FolderBrowserDialog with Environment.SpecialFolder?

问题描述

我目前正在编写一个轻巧灵活的程序来查看和编辑图片.一切进展顺利，但我遇到了障碍. FolderBrowserDialog控件的RootFolder属性是Environment.SpecialFolder类型的，它是一个枚举.由于这种性质，我无法将其值设置为字符串.如何使用FolderBrowserDialog的SelectedPath属性设置FolderBrowserDialog的RootPath属性?

(注意:FolderBrowserDialog用于选择从中打开图像的默认文件夹)

I currently am writing a lightweight and flexible program to view and possibly edit pictures. Everything is going smoothly, but I''ve run into a roadblock. The RootFolder property of a FolderBrowserDialog control is of the Environment.SpecialFolder type, which is an enum. Due to this nature, I can''t set its value as a string. How can I use the SelectedPath property of the FolderBrowserDialog to set the RootPath property for a FolderBrowserDialog?

(Note: The FolderBrowserDialog is for selecting the default folder for opening images from)

推荐答案

尝试使用Environment.SpecialFolder.MyComputer，设置SelectedPath，然后调用.我做了以下工作，效果很好:

Try using Environment.SpecialFolder.MyComputer, set the SelectedPath, and then call ShowDialog(). I did the following and it worked fine:

FolderBrowserDialog dlg = new FolderBrowserDialog();
dlg.RootFolder = Environment.SpecialFolder.MyComputer;
dlg.SelectedPath = @"d:\dev";
dlg.ShowDialog();

我认为您需要看一下:Environment.GetFolderPath(Environment.SpecialFolder).
如果将此调用的结果提供给FolderBrowserDialog，则应该没问题.

Hi,

I think you need to take a look at: Environment.GetFolderPath(Environment.SpecialFolder).
If you feed the result of this call to the FolderBrowserDialog you should be OK.
