How to Use DirectCast in C#

Using the DirectCast function in C# is a great way to make your application run a lot faster. This function is a notch above the CType function in performance and functionality, but it does not provide the same level of coercion, which means that you can use it to cast between a reference and an object type. In addition to the DirectCast function, there are two other casting options. These include a try-cast and a safe cast. The C# try-cast can work with any value type, and the safe cast can work with any reference type. This is a good feature, since it is often necessary to cast between a reference and an object.

The CType function is a little more complicated. It is an IL-generated function, which means that the Visual Basic.NET compiler generates four lines of IL code for the function. It also generates a call to the conversion method, which is the aforementioned function. The CType function does not throw an exception, but it also does not perform any coercion. The function is most useful when converting between object and reference types. The CType function also has the distinction of being a part of the Common Language Runtime, which means that it does not rely on the run-time helper routines used by the VB.NET compiler. It does, however, perform the aforementioned function for you, avoiding the need to resort to the helper functions.

The TryCast function isn’t as complex as the CType function. It’s a good idea to keep TryCast in mind the next time you’re writing code that requires a safe cast, or a good old-fashioned null check. You can also separate your casts from your null checks. For example, it’s only sensible to cast a long to an integer, since a runtime error may occur if the long isn’t converted into an integer. A safe cast is the safest way to do it, and it can be used on any reference type.

The TryCast function also has the distinction of not throwing an exception. The function does, however, have a fairly small performance impact. It’s also the best way to cast between a reference and an object. The only caveat is that the function only works if you know the type of the object. This may be a good thing, since it’s possible that your object may be of a different type than you think, which is another reason to cast between a reference and an object. If you’re in a pinch, you may want to cast the object to a null, but this isn’t the best solution. A better approach is to cast it to an object of a different type, and then cast it to a null object.

The CType function is the best way to cast between a value and an object type. The TryCast function is not as good, but it’s still an excellent option when you need to make the best use of your resources.
