Path.AltDirectorySeparatorChar Field

Provides a platform-specific alternate character used to separate directory levels in a path string that reflects a hierarchical file system organization.

Namespace:  System.IO
Assembly:  mscorlib (in mscorlib.dll)

public static readonly char AltDirectorySeparatorChar

The character stored in this field cannot be in InvalidPathChars. This field can be set to the same value as DirectorySeparatorChar. AltDirectorySeparatorChar and DirectorySeparatorChar are both valid for separating directory levels in a path string.

The value of this field is a backslash ('\') on UNIX, and a slash ('/') on Windows and Macintosh operating systems.

The following code example demonstrates a use of the AltDirectorySeparatorChar field.

Console.WriteLine("Path.AltDirectorySeparatorChar={0}", 
    Path.AltDirectorySeparatorChar);
Console.WriteLine("Path.DirectorySeparatorChar={0}", 
    Path.DirectorySeparatorChar);
Console.WriteLine("Path.PathSeparator={0}", 
    Path.PathSeparator);
Console.WriteLine("Path.VolumeSeparatorChar={0}", 
    Path.VolumeSeparatorChar);

Console.Write("Path.GetInvalidPathChars()=");
foreach (char c in Path.GetInvalidPathChars())
    Console.Write(c);
Console.WriteLine();
// This code produces output similar to the following: 
// Note that the InvalidPathCharacters contain characters 
// outside of the printable character set. 
// 
// Path.AltDirectorySeparatorChar=/ 
// Path.DirectorySeparatorChar=\ 
// Path.PathSeparator=; 
// Path.VolumeSeparatorChar=:
