Question

HI,

I have a collection of strings
eg
“test (9)”
“test (7)”
“test (5)”
“test (3)”

I want to loop use a foreach loop to iterate and find the lowest number I have a regex to extract the number out of each string… I need to loop through all items (which are in the format as in my example above) and find the lowest number…?

foreach (SPListItem item in items)

{

string item = (String)item["Title"];

string itemNumberString = Regex.Match(UniqueCounteryparty, @"\d+").Value;


}

I’m initializing the variable “test” below using array initialization syntax for demo purposes since I’m assuming you have a collection already populated with the strings you need.

  string[] tests = new string[] { "test(1)", "test(2)", "test(3)" };
  int minimum = int.MaxValue;

  foreach(string test in tests)
  {
    int num = ExtractNumber(test);
    if (num < minimum)
      minimum = num;
  }

  //now you have minimum that hold the minimum;

“ExtractNumber” is your function that extracts the number from the string
