Hi All,

I'm trying to test a string to see if it contains another string. I can't use myString.Contains("string") as the string I'm searching for has to be on the LHS of an "=" symbol. For example,

from: "NumberOfGroups = 8"

I want to be able to test if the string contains the text NumberOfGroups and if true retrieve the value 8. I know I can use the split function using "=" as the delimiter. Does anyone know if I can achive this usinging regular expressions? Thank You.

Try:

using System.Text.RegularExpressions;

...

string toFind = "some string";
string toSearchIn = "This is some string that is on the left of an = sign";
string pattern = Regex.Escape(toFind) + "(?=[^=]*=)";

bool contains = Regex.IsMatch(toSearchIn, pattern);
