"A string like this", will become, "a STRING LIKE THIS"
"A StRing LIKE this", will become, "a sTrING like THIS"
etc.
"A StRing LIKE this", will become, "a sTrING like THIS"
etc.
- Code:
public static class StringExtensions
{
public static string InvertCase(this string s)
{
var cArr = s.ToCharArray();
for (var i = 0; i < cArr.Length; i++)
{
var cInt = (int)cArr[i];
if ((cInt >= 65 && cInt <= 90) || (cInt >= 97 && cInt <= 122))
{
cInt ^= 1 << 5;
cArr[i] = (char) cInt;
}
}
return new string(cArr);
}
}

using System;
using System.Linq;
class StringInversion
{
public static void Main()
{
string data = "i Am A mONkeY";
string invStr = new string(data.Select(chr => char.IsLetter(chr) ? (char.IsLower(chr) ? char.ToUpper(chr) : char.ToLower(chr)) : chr).ToArray());
Console.WriteLine(invStr);
}
