Obviously all of those work, if you know the string you want to compare thing to, you don't need to create a variable just to compare (I'm pretty sure, the program I made today seems to work, so I suspect this is right).


string input = HeresSomethingIPreparedEarlier();
if (input.ToLower() == "cake")
    return "pie";

I suspect some of those other functions are there so Java programmers feel more comfortable (eg: in Java you have to use .equals() when comparing a variable string (eg string cake = "pie") to a constant (eg: "pie").

You guys should read:

Will Asrari - String.Compare() versus String.Equals()

then take a look at: New Recommendations for Using Strings in .NET 2.0

Read some of the string comparison methods. In particular this Official MS statement about ToUpper and ToLower:

Users should most certainly be careful when using these functions, since forcing a string to a certain case is often used as a small normalization for comparing strings irrespective of case. If so, consider using a case-insensitive comparison.

I still stand by my original statement that you should use String.Compare and pass the third operator to ignore case. Pass the fourth operator as the current/local language and your strings work internationally.

If you wanted to compare a variable against a known string:

if (String.Compare(input, "cake", true) == 0) {....}

lol, n00bs are taught that method in school when they learn .NET, as it is the proper method.

You are just arguing to increase your contest points. I believe I have seen you use my method before.

Incorrect on both counts. First, the contest has finished. Secondly, I have never used string.Compare() before in my memory. You fail, lulz.
