.NET String.Format() to add commas in thousands place for a number
I have an int that is passed through to the a view and it need to formatting so it is not one big block of number. e.g
0
00
000
000,0
000,000
000,000,000
How can i do this using a for loop?
thanks
You may want to output the integer as i.ToString("###,###,###");
However, this would not display a value if the int is 0.
You could try using System.Drawing.Color to represent the colour value rather than an int. This has a method ToArgb()

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#?

I have a field EmpID (textbox) where user manually enters a 6 digit code. If he enters less than 6 digit then we need to add "0" as prefix to make it a 6 digit code. Example if enters 123, we must make it 000123. If he enters 1234, we must make it 001234.
I want an efficient way for handling this situation. I want to avoid writing multiple if statements. Any better way of doing this?
It's as simple as this:
tbValue = tbValue.PadLeft(6, '0');
You can do this using PadLeft function as below
myString = myString.PadLeft(6, '0');

I already tried to determinate the digits in a sentence using 'isDigit', but this gives me a 'bool' output. I need an 'int' output.
What i want to do is, say, i have the sentence "cheese23"; "2" and "3" will be put in their own variable, so i can add/subtract/multiply/ etc them.
(x=2,y=3;)
help will be hugely appreciated (self-teaching beginner here)
Do:
int[] intArray = "Cheese23".Where(Char.IsDigit).Select(c => int.Parse(c.ToString())).ToArray();
This extracts the numbers in the string in the order and creates an array out of it.
Then you can do intArray[0] to get 2 and intArray[1] to get 3.
Search up LINQ to see how those chain of methods did it.

Why does 0.ToString("#.##") return an empty string instead of 0.00 or at least 0?

I have several decimal numbers that I need to show as strings (no need for decimal places). I use the following code:
mytextblock.text= mydecimalnumber.ToString("#");
However this code will show nothing if the number is 0. I need to display a "0" instead of an empty string. I can do this using if and else but I don't think this is the best solution to do with many decimal variables.
Some user "David.." posted this answer and it worked for me but then he deleted it later:
He mentioned that ToString("#") will only show digits that are not zeros.
In order to default to 0, I should use ToString("0")

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}
