範例

下列範例示範屬性的使用 InvalidPathChars 。

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()

備註

從這個方法傳回的陣列不保證包含檔案和目錄名稱中不正確完整字元集。 一組無效字元可能會因檔案系統而異。 GetInvalidPathChars()請參閱備註，以瞭解此欄位所傳回的字元集。

警告

如果您認為程式碼可能會在與不受信任的程式碼相同的應用程式域中執行，請勿使用 InvalidPathChars 。 InvalidPathChars 是陣列，因此可以覆寫其元素。 如果不受信任的程式碼覆寫 的 InvalidPathChars 元素，可能會導致程式碼因可能遭到惡意探索的方式而故障。
