在文本末尾读取两个整数

Question

I am getting values from the form in the following format:

text 2234-7755

What i want to do is read first four integers than the last four integer values separately. Please let me know how can i read that. Thanks

Answer 1

string[] nums = text.Split("-");
int num1 = Convert.ToInt32(nums[0]);
int num2 = Convert.ToInt32(nums[1]);

If you want to be safer, you can use int.TryParse

Answer 2

use split function and get the first value.

  var original="2234-7755";
  var intArray = original.Split("-");

  int part1 = Convert.ToInt32(intArray[0]);
  int part2 = Convert.ToInt32(intArray[1]);

You can also use Int32.TryParse method if you want more control.

Answer 3

Are you looking for something like this?

string text = "text 2234-7755";

var matches = Regex.Matches(text, @"(\d+)");
if (matches.Count == 2)
{
    int value1 = Convert.ToInt32(matches[0].Groups[1].Value);
    int value2 = Convert.ToInt32(matches[1].Groups[1].Value);
}

Answer 4

If the number is always at the end, has 8 digits and is separated by - you don't need regex:

string number = text.Substring(text.Length - 9);
string[] both = number.Split('-');
int firstNum, secondNum;
if (both.Length == 2 
    && int.TryParse(both[0], out firstNum) 
    && int.TryParse(both[1], out secondNum))
{
    Console.Write("First number is: {0}\r\nSecond number is: {1}", firstNum, secondNum);
}
