示例1: Main
' 导入命名空间
Imports System.IO
Namespace PathExample
Public Class GetCharExample
Public Shared Sub Main()
' Get a list of invalid path characters.
Dim invalidPathChars() As Char = Path.GetInvalidPathChars()
Console.WriteLine("The following characters are invalid in a path:")
ShowChars(invalidPathChars)
Console.WriteLine()
' Get a list of invalid file characters.
Dim invalidFileChars() As Char = Path.GetInvalidFileNameChars()
Console.WriteLine("The following characters are invalid in a filename:")
ShowChars(invalidFileChars)
End Sub
Public Shared Sub ShowChars(charArray As Char())
Console.WriteLine("Char" + vbTab + "Hex Value")
' Display each invalid character to the console.
For Each someChar As Char In charArray
If Char.IsWhiteSpace(someChar)
Console.WriteLine("," + vbTab + "{0:X4}", _
Microsoft.VisualBasic.Asc(someChar))
Else
Console.WriteLine("{0:c}," + vbTab +"{1:X4}", someChar, _
Microsoft.VisualBasic.Asc(someChar))
End If
Next someChar
End Sub
End Class
