Path.AltDirectorySeparatorChar 字段
提供平台特定的替换字符，该替换字符用于在反映分层文件系统组织的路径字符串中分隔目录级别。
**命名空间:**System.IO
**程序集:**mscorlib（在 mscorlib.dll 中）
语法
声明
Public Shared ReadOnly AltDirectorySeparatorChar As Char
用法
Dim value As Char
value = Path.AltDirectorySeparatorChar
public static readonly char AltDirectorySeparatorChar
public:
static initonly wchar_t AltDirectorySeparatorChar
public static final char AltDirectorySeparatorChar
public static final var AltDirectorySeparatorChar : char
备注
在此字段中存储的字符不能位于 InvalidPathChars 中。该字段可被设置为与 DirectorySeparatorChar 相同的值。AltDirectorySeparatorChar 和 DirectorySeparatorChar 都适用于在路径字符串中分隔目录级别。
该字段的值在 Unix 上为反斜杠（“\”），在 Windows 和 Macintosh 操作系统上为斜杠（“/”）。
示例
下面的代码示例演示 AltDirectorySeparatorChar 字段的用法。
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.InvalidPathChars=")
Dim c As Char
For Each c In Path.InvalidPathChars
Console.Write(c)
Next 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.InvalidPathChars=");
foreach (char c in Path.InvalidPathChars)
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=:

for ( int i = 0; i < Path::InvalidPathChars->Length; i++ )
Console::Write( Path::InvalidPathChars[ i ] );
Console::WriteLine();

System.Convert.ToString(Path.AltDirectorySeparatorChar));
Console.WriteLine("Path.DirectorySeparatorChar={0}",
System.Convert.ToString(Path.DirectorySeparatorChar));
Console.WriteLine("Path.PathSeparator={0}",
System.Convert.ToString(Path.PathSeparator));
Console.WriteLine("Path.VolumeSeparatorChar={0}",
System.Convert.ToString (Path.VolumeSeparatorChar));
Console.Write("Path.InvalidPathChars=");
for(int iCtr=0; iCtr<Path.InvalidPathChars.length;iCtr++) {

Console.Write(c);
}
