如何将字符串分成多个部分C# [英] How to split the string in multiple parts C#

问题描述

您好，我有一个字符串，需要将其拆分为多个部分.

字符串strcode:"[e-mail]08032018"

输出应为:

Invitationcode ="qwer-tyui-opas-dfgh"
emailIID ="[e-mail]"
日期="08032018"

我能够检索邀请代码和日期，但在提取电子邮件ID时遇到问题

我尝试过的事情:

邀请码= strcode.substring(0,19)
date = strcode.substring((strcode.length-8)，8)

需要提取电子邮件ID.

Hello I have a string which i need to split in various parts.

string strcode: "[e-mail]08032018"

Output should be:

invitecode = "qwer-tyui-opas-dfgh"
emailIID = "[e-mail]"
date = "08032018"

I am able to retrieve invite code and date but facing problem in extracting email id

What I have tried:

invitecode = strcode.substring(0,19)
date= strcode.substring((strcode.length-8),8)

email id needs to be extracted.

推荐答案

如果您知道邀请代码的前19个字符和数据的后8个字符，那么电子邮件始终是其余的''是吗?

/*错误*/
email = strcode.substring(19，(strcode.length-8))

不对，是:
/*正确*/

Well if you know that invite code is first 19 characters and data is last eight characters the email is always the rest isn''t it?

/*wrong*/
email = strcode.substring(19, (strcode.length-8))

no sorry it is:
/*correct*/

strcode.Substring(19, (strcode.Length - 27));

单元测试在这里:

unit test here:

[TestClass]
    public class UnitTest1
    {
        [TestMethod]
        public void TestMethod1()
        {
            string strcode = "[e-mail]08032018";
            var invitecode = strcode.Substring(0, 19);
            var date = strcode.Substring((strcode.Length - 8), 8);
            var email = strcode.Substring(19, (strcode.Length - 27));
            Assert.AreEqual("qwer-tyui-opas-dfgh", invitecode);
            Assert.AreEqual("[e-mail]", email);
            Assert.AreEqual("08032018", date);
        }
    }

在您的字符串之间添加一个标识符，然后使用它来拆分成一个数组.如何将字符串设置为:

Hi,

Add a identifier between your strings and then use it to split into an array. How about setting your string as :

string strcode: "qwer-tyui-opas-dfgh;[e-mail];08032018" 
 or 
string strcode: "[e-mail]%08032018" 

然后像这样使用它:

Then using it like:

string[] words = s.Split(';'); // words will have all three strings.

尝试一下

try this

string invitecode = strcode.Substring(0, 19);
       string date = strcode.Substring(strcode.Length - 8);
       string emailIID = strcode.Replace(invitecode, "").Replace(date, "");
