正则表达式用于两个字符之间的文本

Question

I'm trying to get some text between two strings in C# in regex expression. The text is in variable ( tb1.product_name ) : Example Text | a:10,Colour:Green Example Text | a:10,Colour:Green

1. Get all text before | , in this case, Example Text
2. Get all text between : and , , in this case, 10

In two differents regex. I try with:

Regex.Match(tb1.product_name, @"\\:([^,]*)\\)").Groups[1].Value

But this doesn't work.

Answer 1

If it is not so necessary to use regex, you can do this simply by using string.Substring & string.IndexOf :

string str = "Example Text | a:10,Colour:Green";
string strBeforeVerticalBar = str.Substring(0, str.IndexOf('|'));
string strInBetweenColonAndComma = str.Substring(str.IndexOf(':') + 1, str.IndexOf(',') - str.IndexOf(':') - 1);

Edit 1:

I feel Regex might be an overkill for something as simple as this. Also if use what i suggested, you can add Trim() at the end to remove whitespaces , if any. Like:

string strBeforeVerticalBar = str.Substring(0, str.IndexOf('|')).Trim();
string strInBetweenColonAndComma = str.Substring(str.IndexOf(':') + 1, str.IndexOf(',') - str.IndexOf(':') - 1).Trim();

string str = @"Example Text |a:10,Colour: Green";
Match match = Regex.Match(str, @"^([A-Za-z\s]*)|$");
Match match2= Regex.Match(str, @":([0-9]*),");
//output Example Text
Console.WriteLine(match.Groups[1].Value);
//output 10
Console.WriteLine(match2.Groups[1].Value);
