What type is txt? If it is textBox control you need: txt.Text.Contains.... — apomene, Jun 18 '20 at 12:23
@MatthewRodwell - when you include errors here, copy and paste them *exactly*. C# is case sensitive (Contains, not contains), and certainly the error actually says "...takes 2 **arguments**". — Code Stranger, Jun 18 '20 at 12:40
Because giving accurate info for a problem is extremely important to getting accurate help? — Code Stranger, Jun 18 '20 at 12:47
but if the person who is asking for help doesn't know as much as say you how can that person give more when they don't bloody know — Matthew Rodwell, Jun 18 '20 at 12:58

This is because of the version of .NET you're using.

Notice .NET 4.8 only has one overload: Contains(string)

However, .NET Core 3.1 has multiple overloads, including the one you're using: Contains (string, StringComparison)

There are ways around this, if you can't change frameworks. See this post for one example: Case insensitive 'Contains(string)'
