问题描述

大家好

我有这样的字符串:

Hi all

I have a string like this:

string abc = "  /*some 10 lines of code */   
    // Program Begin
    {
          //Some Code Here
          //Some Code Here
          //Some Code Here
          //Some Code Here
          //Some Code Here
    }
    // Program End
    //some liens of code
    //some liens of code";

我只需要"//程序开始"和"//程序结束"之间的代码.

怎么做.
我在Google中搜索，但未得到任何有效结果.

请帮助

预先感谢.

I want only the code between "// Program Begin" and "// Program End".

How to do this.
I searched in Google and not get any effective result.

Please Help

Thanks in advance.

推荐答案

您可以使用System.String.IndexOf("//Program Begin")和
System.String.IndexOf("//程序结束")
在此处详细说明 [此处详细说明 [

You can find the index of your start element and end element by using System.String.IndexOf("// Program Begin") and
System.String.IndexOf("// Program End")
details here[^]
Then you can do a System.String.Substring(firstIndex, numberOfcharacters)
details here[^]
The numberOfCharacters can be retrieved by subtracting both indexes in the right order.

Good luck!
