Difference in string comparison result b/w == and String#replace with == [duplicate]

Answer 1

DO this way

("String".replace('t','T').Tostring() ==  ("String".replace('t','T')).ToString()

This will solve your problem because the replace statement should be converted to string before eveluation.

You can also user the String.Equals for this or better you use ignore case as you mention in your question.
