How can I count the numbers in a string of mixed text/numbers
Solution 1
Using LINQ :
var count = jobId.Count(x => Char.IsDigit(x));
or
var count = jobId.Count(Char.IsDigit);
Solution 2
int x = "xxx123432".Count(c => Char.IsNumber(c)); // 6
or
int x = "xxx123432".Count(c => Char.IsDigit(c)); // 6
The difference between these two methods see at Char.IsDigit and Char.IsNumber.
Solution 3
Something like this maybe?
string jobId = "xxx123432";
int digitsCount = 0;
foreach(char c in jobId)
{
if(Char.IsDigit(c))
digitsCount++;
}
And you could use LINQ, like this:
string jobId = "xxx123432";
int digitsCount = jobId.Count(c => char.IsDigit(c));

So what I'm trying to do, is take a job number, which looks like this xxx123432, and count the digits in the entry, but not the letters. I want to then assign the number of numbers to a variable, and use that variable to provide a check against the job numbers to determine if they are in a valid format.
I've already figured out how to perform the check, but I have no clue how to go about counting the numbers in the job number.
Thanks so much for your help.
