Char.ToUpperInvariant Method
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Converts the value of a Unicode character to its uppercase equivalent using the casing rules of the invariant culture.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- c
- 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).
Use String.ToUpperInvariant to convert a string to uppercase.
