Finding an integer number in a string surrounded by spaces

Hello Experts,

I need a function that returns a true if a string contains an integer.  But it has to be a true number, no alpha numerics.

example string 1: "This is a string with a number: 123456 so that's true?"
example string 2: "This string has alpha-numeric data: B123456D so that's false?"

So essentially an integer surrounded by spaces.

bool IsContainsInteger(string value){
foreach(var str in value.Split(' ')){
int tmp;
if(int.TryParse(str, out tmp))
return true;
return false;

Never mind. I see what you mean now. You can simply add word boundaries to the answer I gave you in the other question:

string number = Regex.Match(source, @"\b\d+\b").Value;
