Inconsistent accessibility

Question

I am getting the following error

Inconsistent accessibility: parameter type \'Db.Form1.ConnectionString\' is less accessible than method \'Db.Form1.B

Answer 1

Your ConnectionString type is not public, yet, a public method of a public class is using it as a parameter. You must also make the type public, for instance:

// If it's a class
public class ConnectionString { ... }
