Visual Studio文件选择器

Question

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?

Answer 1

this should do the trick:

string path;
OpenFileDialog file = new OpenFileDialog();
if (file.ShowDialog() == DialogResult.OK)
{
    path = file.FileName;
}

the string path should now contain the selected file path

Answer 2

OpenFileDialog should 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.
