C# String comparison fails for string having special character in it [closed]

Answer 1

For exact string equality you should use StringComparer.Ordinal. And, as I can see that you don't care about case, it's better for you to use StringComparer.OrdinalIgnoreCase :

if(StringComparer.OrdinalIgnoreCase.Equals(myInput.Trim(), item.Trim()))
{
    count++;
}
