拆分字符串 C#

Question

I need a little bit help. I have a string

string source = "Mobile: +49 (123) 45678Telephone: +49 (234) 567890Fax: +49 (345) 34234234";

And I want to split in this:

Mobile: +49 (123) 45678
Telephone: +49 (234) 567890
Fax: +49 (345) 34234234

Thanks for your support BR Thomas

Answer 1

You can use Regex.Matches() :

string source = "Mobile: +49 (123) 45678Telephone: +49 (234) 567890Fax: +49 (345) 34234234";

string[] phones = Regex
                 .Matches(source, "[A-Za-z]+: \\+([0-9)( ])+")
                 .Cast<Match>()
                 .Select(i => i.ToString())
                 .ToArray();

OR

You can use IndexOf() :

string source = "Mobile: +49 (123) 45678Telephone: +49 (234) 567890Fax: +49 (345) 34234234";

var telephoneIndex = source.IndexOf("Telephone", StringComparison.InvariantCulture);
var faxIndex = source.IndexOf("Fax", StringComparison.InvariantCulture);

string[] phones =
{
    source.Substring(0, telephoneIndex - 1),
    source.Substring(telephoneIndex, faxIndex - 1),
    source.Substring(faxIndex, source.Length - faxIndex)
};

Answer 2

Only because I'm bored

This function returns a dictionary of the three phone numbers.

Dictionary<String, String> ParseTelephones(string source)
{
    var tags = new[] {"Telephone:","Fax:","Mobile:"};
    var dict = new Dictionary<String, String>();

    tags.Any(a => { source = source.Replace(a, "|" + a); return true; });

    source.Split("|")
          .Skip(1)
          .Select(a => a.Split(":").Trim())
          .Any(a => { dict.Add(a[0], a[1]); return true;})
          .ToList();

    return dict;
}
