C＃FilePath帮助

Question

I use OpenFileDialog to search for a specific file. When the user chooses the file, I want to store that path in a variable. However, these doesn't seem to be an option for this within OpenFileDialog?

Does anybody know how to do this?

Thanks.

Edit: This is Winforms, and I don't want to save the path inclusive of the filename, just the location where the file is.

Answer 1

如果使用的是WinForms，请使用OpenFileDialog实例的FileName属性。

Answer 2

On WinForms:

String fileName;
OpenFileDialog ofd = new OpenFileDialog();
DialogResult dr = ofd.ShowDialog();
if (dr == DialogResult.Ok) {
  fileName = ofd.FileName;
}

//getting only the path:
String path = fileName.Substring(0, fileName.LastIndexOf('\\'));

//or easier (thanks to Aaron)
String path = System.IO.Path.GetDirectoryName(fileName);

Instead of copy pasting answers from MSDN I'll just link to them.

MSDN documentation on Forms OpenFileDialog .

MSDN documentaiton on WPF OpenFileDialog .

Please try to look for a answer before posting questions.

Answer 4

You store the path ... somewhere else!

What I usually do is create a user-scoped configuration variable.

Here's a sample of its use:

var filename = Properties.Settings.Default.LastDocument;
var sfd = new Microsoft.Win32.SaveFileDialog();
sfd.FileName = filename;
/* configure SFD */
var result = sfd.ShowDialog() ?? false;
if (!result)
    return;
/* save stuff here */
Properties.Settings.Default.LastDocument = filename;
Properties.Settings.Default.Save();

To save just the directory, use System.IO.Path.GetDirectoryName()

Answer 5

这将基于OpenFileDialog的FileName属性检索路径。

String path = System.IO.Path.GetDirectoryName(OpenFileDialog.FileName);

Answer 6

对话框关闭后，OpenFileDialog对象上应有一个文件路径（或类似内容）属性，它将存储用户输入的任何文件路径。

Answer 7

Try FileName. Or FileNames if you allow multiple files to be selected(Multiselect=true)
