Question

嗨我想得到Crm和行中的数字 TENX

public string GetCrmSubjectNum()
{
    string final = //;

    return "";
}

Answer 1

有点不清楚你想要什么。 如果你总是有＆＃34; CRM＆＃34;在这个主题中，你可以这样做：

using System;

   namespace ConsoleApplication1
   {
    class Program
    {


        static void Main(string[] args)
        {
            string emailsubject = "Email Test 2 CRM:0276002";

            emailsubject = GetCrmSubjectNum(emailsubject);

            Console.WriteLine(emailsubject);

            Console.Read();
        }



        public static string GetCrmSubjectNum(string emailsubject)
        {
           emailsubject = emailsubject.Remove(0, emailsubject.IndexOf("CRM"));

            return emailsubject;
        }
    }
}

Answer 2

我会选择这个，因为Substring（）是最快的方式：

public string GetCrmSubjectNum(string emailSubject)
{
    return emailSubject.Substring(emailSubject.IndexOf("CRM:", StringComparison.Ordinal) + "CRM:".Length);
}
