Online Upper Case Converter

So, in my quest to learn C#, I am attempting to create an interactive story that changes based on some of the input that the user had submitted. If the user types in "Bobby" in this case, the narrator begins to talk like Hank Hill. However, with how it's programmed, the input is case sensitive.

I have tried one thing suggestion that I saw which was to format the if statement as:

if (boyName.ToUpper() == "Bobby")

But that did not trigger the if command with different letter cases

 Console.WriteLine($"{beginning} \n What was the boy's name?"); boyName = Console.ReadLine();  if (boyName == "Bobby")   {   Console.WriteLine("That boy ain\'t right, I tell ya what... ");   Console.ReadKey();   Console.WriteLine($"{boyName} boy dang climbed a big ol' tree...");    Console.ReadKey();   }   else    {    Console.WriteLine($"The kid named {boyName} climbed a tree...");    Console.ReadKey();    }

I expect to have a line of code that will trigger the if condition no matter the case. However, everything I tried has not changed that. It needs to be specifically "Bobby" or it will trigger the else condition

I'm setting up a data table & expected to transform all data to be in lower-case, thought it would look neat. How can I do that ?

I've tried using the uppercase filter but it does not work. I've tried doing it two ways:

<input type="text" ng-model="test" uppercase/>

and

<input type="text" ng-model="{{test | uppercase}}"/>

The 2nd triggers a javascript error:

Syntax Error: Token 'test' is unexpected, expecting [:]

I want the text to be forced to uppercase as the user types in the textbox.

How can I do that?

I would like to change the chars of a string from lowercase to uppercase.

My code is below, the output I get with my code is a; could you please tell me where I am wrong and explain why?Thanks in advance

test = "AltERNating"def to_alternating_case(string):    words = list(string)    for word in words:        if word.isupper() == True:            return word.lower()        else:            return word.upper()  print to_alternating_case(test)

I see that colors in CSS properties values are commonly written in the uppercase form:

.foo .bar {  background-color: #A41B35;  color: #FFF;}

But you can also use:

/* Same same */.foo .bar {  background-color: #a41b35;  color: #fff;}

It looks like using lowercase values does the same, and, CSS values for colors are not case-sensitive. Lots of graphic design software also use the uppercase form. And it is very common to find uppercase notations in source code, it looks like there is something like a tradition.

I understand about the consistency thing, that it should be the same everywhere in you software, but as the standard doesn't give a good indication, people do what they want or what they are told to do.

Is there rational reasons for this, like historic, compatibility, old IE6 hacks, performances or practical reasons?
