String manipulation

YoungLuke · April 14th, 2007, 03:50 PM

I have an .aspx file with a string that is one line of data, this line has multiple instances of "ServiceName=" i'm working on a program that extracts each "ServiceName=" from the file, but using sting.INdexof only give me the first instance of "ServiceName=" how do iterate through all instances of "ServiceName=" when it is read as one line?

Are the occurrences of each item separated by something? If they are, you could split the string into an array, then parse each array item for the name(s) you are looking for.

Hi,

Alternatively, you can use a Regular Expression to get the value, and it will return an matching groups. Regular Expressions sound a bit overkill, but in your example, no knowledge is required.

Code:

using System.Text.RegularExpressions;

string text = "ServiceName=";

MatchCollection matches = Regex.Match(sourceString, text, RegexOptions.SingleLine);

if(matches.Count==0)
     //No matches found
else
{
     foreach(Match m in matches)
     {
          //Match is contained at m.Value;
     }
}

I hope this helps,

Regards,

Dominic
