How retrieve only filename from save file dialog [duplicate]

问题

This question already has answers here:

Obtaining only the filename when using OpenFileDialog property “FileName” (2 answers)

Closed 2 years ago.

I have a save file dialog and i want to get only the filename entered. Equivalent for

    openfiledialog.SafeFileName;

Save file dialog has no SafeFileName Property and FileName returns both filename, path and extension. Pls how do i extract only file name.

回答1:

If you want the filename with extension use Path.GetFileName(). If you want it without the extension as well use Path.GetFileNameWithoutExtension().

public void Test(string fileName)
{
    string path = Path.GetDirectoryName(fileName);
    string filename_with_ext = Path.GetFileName(fileName);
    string filename_without_ext = Path.GetFileNameWithoutExtension(fileName);
    string ext_only = Path.GetExtension(fileName);
}

See MSDN for further details, especially the Path class which has a number of useful methods:

Also found another solution to my problem

    FileInfo fi = new FileInfo(saveFileDialog1.FileName);
    string text = fi.Name;
