Char.ToUpperInvariant(Char) Method in C#
The Char.ToUpperInvariant() method in C# is used to convert the value of a Unicode character to its uppercase equivalent using the casing rules of the invariant culture.
Syntax
public static char ToUpperInvariant (char ch);
Above, the parameter ch is the Unicode character to convert.
Let us now see an example to implement the Char.ToUpperInvariant() method −
Example
using System;
public class Demo {
public static void Main(){
char ch = 'q';
char res = Char.ToUpperInvariant(ch);
Console.WriteLine("Value = "+ch);
Console.WriteLine("Uppercase Equivalent = "+res);
}
}Output
This will produce the following output −
Value = q Uppercase Equivalent = Q
Let us now see another example −
Example
using System;
public class Demo {
public static void Main(){
char ch = 'r';
char res = Char.ToUpperInvariant(ch);
Console.WriteLine("Value = "+ch);
Console.WriteLine("Uppercase Equivalent = "+res);
}
}Output
This will produce the following output −
Value = r Uppercase Equivalent = R
