如何获取字符串中第二个逗号的索引 [英] How to get the Index of second comma in a string

问题描述

我在一个包含两个逗号以及制表符和空格的数组中有一个字符串。我想在该字符串中切两个字，两个都放在逗号前，我真的不在乎标签和空格。

我的字符串看起来像这样：

  String s = Address1芝加哥，伊利诺伊州Address2底特律，密歇根州 
  

我得到第一个逗号的索引

  int x = s.IndexOf（'，'）; 
  

然后从那里，我在第一个逗号的索引前切下字符串。

  firstCity = s.Substring（x-10，x）.Trim（）//修剪字母C之前的空格; 
  

那么，如何获取第二个逗号的索引，以便获取第二个字符串？ / p>

非常感谢您的帮助！

解决方案

您必须使用代码

  int index = s.IndexOf（'，'，s.IndexOf（'，'）+ 1）; 
  

您可能需要确保不要超出字符串的范围。我会把那部分留给你。

I have a string in an Array that contains two commas as well as tabs and white spaces. I'm trying to cut two words in that string, both of them before the commas, I really don't care about the tabs and white spaces.

My String looks similar to this:

String s = "Address1       Chicago,  IL       Address2     Detroit, MI"

I get the index of the first comma

int x = s.IndexOf(',');

And from there, I cut the string before the index of the first comma.

firstCity = s.Substring(x-10, x).Trim() //trim white spaces before the letter C;

So, how do I get the index of the second comma so I can get my second string?

I really appreciate your help!

解决方案

You have to use code like this.

int index = s.IndexOf(',', s.IndexOf(',') + 1);

You may need to make sure you do not go outside the bounds of the string though. I will leave that part up to you.
