Visual Studio file selector
提问by kaj
I am new to .NET and the Visual Studio IDE. How to I add to a form a component that lets the user browse the file system to select a certain file which will then allow me to programmatically use the selected path as a string variable?

OpenFileDialogshould suit your needs. You'll probably need to put a button (or some other clickable type UI element) on the page that will pop the dialog up. Then once the user has selected a file and clicked "OK" you'll just check the response for which file was selected.
OpenFileDialog应该适合您的需要。您可能需要在将弹出对话框的页面上放置一个按钮（或其他一些可点击类型的 UI 元素）。然后，一旦用户选择了一个文件并单击“确定”，您只需检查选择了哪个文件的响应。

this should do the trick:
这应该可以解决问题：
string path;
OpenFileDialog file = new OpenFileDialog();
if (file.ShowDialog() == DialogResult.OK)
{
path = file.FileName;
}
the string path should now contain the selected file path
字符串路径现在应该包含选定的文件路径
**Edit: ** As mentioned in a comment below, OpenFileDialog is disposable so should be wrapped in a using statement.
**编辑：** 正如下面的评论中提到的，OpenFileDialog 是一次性的，所以应该包装在 using 语句中。
