By `compare` do you mean if they are equal or really compare in order to sort them? — CSharpie, Aug 09 '17 at 11:11
@CSharpie `compare` and `really compare` - new word in string comparison history — tchelidze, Aug 09 '17 at 11:12
Not to transform upper and lower case used any methods as inbuilt I don't know method name to compare directly without transfrom — Pawan Kumar Tiwari, Oct 03 '17 at 04:11

Transform both to lowercase strings and compare after that

a.ToLower() == b.ToLower()

This checks for equality and does not compare the two given strings. – CSharpie Aug 09 '17 at 11:10
@CSharpie What you mean ? – tchelidze Aug 09 '17 at 11:11
OP asked for `Compare`, your solution only checks equality. Compare is used to sort things. – CSharpie Aug 09 '17 at 11:14

Also using ToLower() in this way is bad practice. – CSharpie Aug 09 '17 at 11:29

Every answer so far was checking for equality, here is mine actually comparing:

switch(string.Compare(a, b, StringComparison.CurrentCultureIgnoreCase))
{
   case  1: Console.WriteLine("a is greater"); break;
   case  0: Console.WriteLine("a and b are equal"); break;
   case -1: Console.WriteLine("b is greater"); break;
}

You can test it here https://dotnetfiddle.net/h75xZ8

If you arent sure about the comparison, you can look it up here: https://msdn.microsoft.com/en-us/library/system.stringcomparison(v=vs.110).aspx
