Examples
The following example demonstrates the use of the InvalidPathChars property.
Console::WriteLine( "Path::AltDirectorySeparatorChar={0}", (Path::AltDirectorySeparatorChar).ToString() );
Console::WriteLine( "Path::DirectorySeparatorChar={0}", (Path::DirectorySeparatorChar).ToString() );
Console::WriteLine( "Path::PathSeparator={0}", (Path::PathSeparator).ToString() );
Console::WriteLine( "Path::VolumeSeparatorChar={0}", (Path::VolumeSeparatorChar).ToString() );
Console::Write( "Path::InvalidPathChars=" );
for ( int i = 0; i < Path::InvalidPathChars->Length; i++ )
Console::Write( Path::InvalidPathChars[ i ] );
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=:
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=:
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()=")
Dim c As Char
For Each c In Path.GetInvalidPathChars()
Console.Write(c)
Next c
Console.WriteLine()

Remarks
The array returned from this method is not guaranteed to contain the complete set of characters that are invalid in file and directory names. The full set of invalid characters can vary by file system. Refer to the GetInvalidPathChars() remarks to learn what the set of characters returned by this field is.
Caution
Do not use InvalidPathChars if you think your code might execute in the same application domain as untrusted code. InvalidPathChars is an array, so its elements can be overwritten. If untrusted code overwrites elements of InvalidPathChars, it might cause your code to malfunction in ways that could be exploited.
