I need Help with comparing

Question

so im trying to compare two text boxes and write the differences to a different text box on a button click for example:

textbox1.Text = "This is my name right here

and my birthday is may 12"

textbox2.Text = "This is my name right there

and my birthday is may 25"

//click compare button

textbox3.Text = " Your differences are: Line 1, Here/There.

                                                          Line 2, 12/25 (Date)."

//Date meaning the date you clicked the compare button and it being at end of your file text,  im also wanting it to save to a text file where i want and the name i want using a button click.  PLEASE HELP!!!

Answer 1

Step 1 : use the string[] w1 = string.split(' ') ; to get individual values to an array of words .

Step 2 : use the string[] w2 = string.split(' ') ; to get individual values to an array of words  of second text box.

step 3: use for(i=0-->i=w1.length) compare w1[i] and w2[i] if same then ignore else add into a string to provide 

out put .

If you want multiline output read lineby line from the multiline text box and do the same.

It will work if you dont have situation like this: 

string1 = "This is my name right here and my birthday is may 12";
string2 = "This is not my name right here and my birthday is may 12";

they are almost identical but your code will give lot of warnings

diff'ing is complicated. I would suggest searching for a library. I found this one : http://diffplex.codeplex.com/#What is the DiffPlex Project?

Yup you are true . I have taken some assumptions as the requirement was not clear enough.There are even more cases that must be considered .
