GetInvalidFileNameChars() 不包含所有非法字符

根据 http://msdn.microsoft.com/en-us/library/system.io.path.getinvalidpathchars%28v=vs.110%29.aspx Path.GetInvalidFileNameChars()应该给出以下输出

// Note: Some characters may not be displayable on the console. 
// The output will look something like: 
// 
// The following characters are invalid in a path: 
// Char    Hex Value 
// ",      0022 
// <,      003C 
// >,      003E 
// |,      007C 
// ... 
// 
// The following characters are invalid in a filename: 
// Char    Hex Value 
// ",      0022 
// <,      003C 
// >,      003E 
// |,      007C 
// ...

但是我只得到

Char    Hex Value
,   0000
/,  002F
