How to use StringComparison for strings in C#?

You can use regular expression to match a string search in C#. You also have the option to ignore case.

if (System.Text.RegularExpressions.Regex.IsMatch(s, sPattern, System.Text.RegularExpressions.RegexOptions.IgnoreCase))

I'm not sure if you are using .NET 1.1, but it did not contain the method Contains. You have to use IndexOf. .NET 2.0 added the method Contains (per MSDN). With IndexOf, you can use StringComparison.

I don't believe string has an overload of Contains taking a StringComparison. However, you could use IndexOf which does:

if (body.IndexOf("software", StringComparison.CurrentCultureIgnoreCase) != -1)

String.Contains only take one parameter - your code should be

bodyText.Contains("software");
