I have two strings.
stringV1 = "123456";
stringV2 = "102300456";
First I need to compare them.
If stringV2 has some changes, this new text should be highlighted like this:
"1'0'23'00'456"

this has been discussed here already sometimes...

What I need to do seems simple enough but I can't seem to find a good way to do it. My app reads text off of a document but sometimes gets it wrong. Users are allowed to change the text in a verification step. What I need to know is how many characters changed, including case.
For example,
Original value: i23 MAin St
Value changed to: 123 Main Street
The number of characters changed in this instance would be 6. I then need to capture this value in a variable for later use. Is there a good way to do this in c#?

.NET String.Format() to add commas in thousands place for a number
Hi Guys,
I have got 26750 in my string variable, something like below:
string str = "26750";
Now before showing on page, I want it to be converted into "26,750" format using c#. This value can increase as well as decrease also according to the result, so my format should work in both the cases.
Please suggest!
EDIT:
As I have written I have got string type value in my variable, I am trying with below code, but it is not working for me.
spnMiles.InnerHtml = String.Format("{0:n}", Miles);
It is not changing to the number format.
Please suggest!

I am trying to display a code like ABC/DEF/00012 or ABC/EDF/01234 or ABC/DEF/00009
I use RegEx mask \w{3}/\w{3}/?????
The question mark is hard part that I could not figure it out.
Basically, I try to display the code with characters and numbers. I want to automatically add leading zeros on the number.

Seems that you're trying to match 5 digits at the end:
\w{3}/\w{3}/\d{5}
