如何确定动态文本中子字符串的计数？

Question

ok so I have this string.

Next: Warrant Officer Grade 2
21,202 / 33,000
21,202 / 33,000

It is a substring I have obtained from a long thing of text. Now "Warrent Officer Grade 2" as well as the numbers can be dynamic (I am loading these variables from a webpage) If there is a number in the ones or hundreds it does not append 0's so the exp for less than a thousand would look like "478" instead of 00,478.

Now my question is how to I obtain just "Warrant Officer Grade 2"? I already have this

int indexOfNext = myString.IndexOf("Next") + 6;  
//Below is what I need to obtain  
int count = 0;  
string newString = myString.Substring(indexOfNext, count);

But how would I help determine the count for getting the rank? or would It just be simple to create an array with all the ranks and the length of each rank?

Answer 1

You can use regular expression to search for the name and level for example

var regExp = new Regex(@"^Next: (?<name>[^\d]+) Grade (?<level>[\d]+)");

this will match all lines starting with Next: followed with the name, Grade word and level. The captured values of name and level groups can be retrieved later

var match = regExp.Match(input);
var level = match.Groups["level"].Value; 

or modify it the way you want it.
