Creation code-128c in .NET Restrict Access to Resources

Undesired boxing When v is passed as an argument to the CompareTo method, it must be boxed because CompareTo expects an Object . The lack of type safety This code compiles, but an InvalidCastException is thrown inside the CompareTo method when it attempts to cast o to SomeValueType .

This returns the following:

Now that we know how to wire together the components in a Spring application, we can put this knowledge to use in the Spring implementation of the TechConf application. The approach we will take is fairly similar to the implementation using EJB3 on JBoss covered in 5. We actually will reuse the same service, DAO, and DTO interfaces. (After all, that s the point of using interfaces; reusability and the ability to swap implementations.) We will start by developing a set of Spring-Hibernate DAOs and DynaDTO DTOs. These DAOs and DTOs will then be injected into the implementations of the service interfaces.

When compiling this method, the C# compiler produces the following message: "messagepil17: 'int' does not contain a definition for 'ToSingle'." This error message confuses the developer because it s clearly stating that the Int32 type doesn t define a ToSingle method when, in fact, it does . To call ToSingle on an Int32, you must first cast the Int32 to an IConvertible, as shown in the following method:
