Examples

The following code shows how to call the GetRelativePath method.

// "C:/Program Files/Microsoft" relative to "C:/Program Files/Common Files" is "../Microsoft"
Console.WriteLine(Path.GetRelativePath("C:/Program Files/Common Files", "C:/Program Files/Microsoft"));
// "C:/Program Files/Microsoft" relative to "C:/Program Files/" is "Microsoft"
Console.WriteLine(Path.GetRelativePath("C:/Program Files/", "C:/Program Files/Microsoft"));

// This code produces output similar to the following:
//
// ../Microsoft
// Microsoft

' "C:/Program Files/Microsoft" relative to "C:/Program Files/Common Files" is "../Microsoft"
Console.WriteLine(Path.GetRelativePath("C:/Program Files/Common Files", "C:/Program Files/Microsoft"))
' "C:/Program Files/Microsoft" relative to "C:/Program Files/" is "Microsoft"
Console.WriteLine(Path.GetRelativePath("C:/Program Files/", "C:/Program Files/Microsoft"))

' This code produces output similar to the following:
'
' ../Microsoft
' Microsoft

Remarks

Paths are resolved by calling the GetFullPath method before calculating the difference. The method uses the default file path comparison for the current platform (StringComparison.OrdinalIgnoreCase for Windows and MacOs, StringComparison.Ordinal for Linux.
