I am getting this error. Can you help me with this issue?  Please be very specific with the discussion.  I am a student and in of need of information.  I have been given permission to get help with my projects from tutors.  

I must create a script that takes text that a user enters into a form field and converts it to title case capitalization.  Use a split()  method to split words in the string into an indexed array.  Then create a for loop that uses another split() method that splits each word in the elements of the indexed array into another another indexed array of characters.  Within the for loop, us he ToUpper() method to convert the first element in the second array (which represents the first characters in the word to uppercase) to uppercase, and then use the Join() method to rebuild the array of words in the text string.  Execute a final Join() method to convert the array of words back into a single text strin.  Save the project as TitleCase.

A NullReferenceException means that an object you are trying to use is not initialized.

If you put the cursor over myText when you get the error, you will probably see that its value is null. This means that your request did not return any value. Your "stringOfWords" element is probably empty.

Whenever you are retrieving information and expect that it could be empty, you need to check for the condition before using the returned value:
string myText = Request.Form["stringOfWords"];
string[] myTextArray;

if ( !( myText == null ) )
     myTextArray = myText.Split ( ' ' );
else
     // Output a message or deal with the situation any way you see fit

Open in new window

Further on, no need to split the string into an array of characters. A .NET string is already an array or characters. You can access them individually as myTextArray[0][0], myTextArray[0][1]...myTextArray[1][0], myTextArray[1][1]...
I leave the rest to you... you need to work a little in order to learn :-)

string myText = Request.Form["stringOfWords"];
string[] myTextArray = myText.Split(' ');

This is the way that I did it.  Thanks for the hint.  I have problem with another issue. Thanks again.
