Converts the value of a Unicode character to its uppercase equivalent using the casing rules of the invariant culture.

public:
 static char ToUpperInvariant(char c);
public static char ToUpperInvariant (char c);
static member ToUpperInvariant : char -> char
Public Shared Function ToUpperInvariant (c As Char) As Char

Parameters

c
Char

The Unicode character to convert.

Returns

Char

The uppercase equivalent of the c parameter, or the unchanged value of c, if c is already uppercase or not alphabetic.

Remarks

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.
