Type:
System::Char
The Unicode character to convert.
Return Value
Type: System::CharThe uppercase equivalent of the c parameter, or the unchanged value of c, if c is already uppercase or not alphabetic.
If your application is unaffected by the current culture and depends on the case of a character changing in a predictable way, use the ToUpperInvariant method. The ToUpperInvariant method is equivalent to ToUpper(Char, CultureInfo.InvariantCulture).
