如何在字符串中查找符号 [英] how to find symbol in a string

问题描述

我的字符串是
3例
字符串str = dotnet-Karnataka;
字符串str1 = -karnataka;
字符串str2 = dotnet-;

我的弦像这样
当我基于''-''
分割字符串时 我想找到地方.
dotnet排名第一，卡纳塔克邦(karnatak)排名第二.

字符串str = -karnataka;
这是第二名.

字符串str = dotnet-
这是第一名.

下次更改我的字符串时:string str = -Hyderabad;
我想找到位置，第一名或第二名

接下来我的字符串是字符串str = PHP-;
我想找到该位置的第一名或第二名.

就像我的字符串是动态更改的.

请帮忙...
谢谢.

推荐答案

你好，

您首先分割字符串.然后检查第一部分是否为Contains``-''.

例如，如果string为" PHP-".您只是拆分了字符串并获得了两个不同的值.
在第一部分中，您将获得"PHP"，第二部分中将获得-".然后确定"PHP" deoes不包含-".表示它位于第一位.
-海德巴德"也发生同样的事情.在这种情况下，海德巴德"将排在第二位.

谢谢

Hello,

You first split the string. Then Check whether the first part Contains ''-'' .

For example if string is ''PHP-'' . You just split the string and got two different values .
In first part you will get ''PHP'' and second part ''-'' . then it is sure that ''PHP'' deoes not contains ''-''. means it is in first place .
same thing happens for ''-Hyderbad'' also . For that case ''Hyderbad'' will be at second position .

thanks

尝试此代码段

Try this snippet

string str = "dotnet-Karnataka";
      string str1 = "-karnataka";
      string str2 = "dotnet-";

      string[] array = str.Split('-');
      if (array.Length > 0)
      {
          string position1 = array[0];
          string position2 = array[1];
      }
