                                                char qualifier,
                                                bool stripQualifierFromResult)
        {
            string pattern = string.Format(
                @"{0}(?=(?:[^{1}]*{1}[^{1}]*{1})*(?![^{1}]*{1}))",
                Regex.Escape(delimiter.ToString()),
                Regex.Escape(qualifier.ToString())
            );

            string[] split = Regex.Split(text, pattern);

            if (stripQualifierFromResult)
                return split.Select(s => s.Trim().Trim(qualifier)).ToArray();
            else
                return split;
        }

Just as the error implies:  put your extension into a static class. For example:

public static class MyExtensions
{
public static string[] SplitWithQualifier(this string text,
                                                char delimiter,
                                                char qualifier,
                                                bool stripQualifierFromResult)
        {
            string pattern = string.Format(
                @"{0}(?=(?:[^{1}]*{1}[^{1}]*{1})*(?![^{1}]*{1}))",
                Regex.Escape(delimiter.ToString()),
                Regex.Escape(qualifier.ToString())
            );

            string[] split = Regex.Split(text, pattern);

            if (stripQualifierFromResult)
                return split.Select(s => s.Trim().Trim(qualifier)).ToArray();
            else
                return split;
        }
}

Open in new window


As long as you have the namespace containing this new class imported (i.e. brought in via a using statement), then you will be able to use the extension method.
