There are three situations in which an explicit reference conversion will succeed at run time that is, not raise an InvalidCastException exception. The first case is where the explicit conversion is unnecessary that is, where the language would have performed an implicit conversion for you anyway. For example, in the code that follows, the explicit conversion is unnecessary because there is always an implicit conversion from a derived class to one of its base classes. class A { } class B: A { } ... B myVar1 = new B(); A myVar2 = (A) myVar1;

The second case is where the source reference is null. For example, in the following code, even though it would normally be unsafe to convert a reference of a base class to that of a derived class, the conversion is allowed because the value of the source reference is null. class A { } class B: A { } ... A myVar1 = null; B myVar2 = (B) myVar1;

The third case is where the actual data pointed to by the source reference could safely be converted implicitly. The following code shows an example, and Figure 18-21 illustrates the code. The implicit conversion in the second line makes myVar2 think that it is pointing to data of type A, while it is actually pointing to a data object of type B. The explicit conversion in the third line is casting a reference of a base class to a reference of one of its derived classes. Normally this would raise an exception. In this case, however, the object being pointed to actually is a data item of type B.

matrices as done in many recipes of this book. These matrices allow the vertex shader in your graphics card to map the 3D coordinates from the object to the correct pixels on your screen. In this case, however, you ve already defined the positions of your two triangles in screen space! So, there is no need for setting these matrices, because now the vertex shader will not change the positions of the vertices and simply pass them to the pixel shader, as you ll see in the HLSL code.

All C# types, including the value types, are derived from type object. Value types, however, are efficient, lightweight types that do not, by default, include their object component in the heap. When the object component is needed, however, you can use boxing, which is an implicit conversion that takes a value type value, creates from it a full reference type object in the heap, and returns a reference to the object. For example, Figure 18-22 shows three lines of code. The first two lines of code declare and initialize value type variable i and reference type variable oi. In the third line of code, you want to assign the value of variable i to oi. But oi is a reference type variable and must be assigned a reference to an object in the heap. Variable i, however, is a value type and doesn t have a reference to an object in the heap. The system therefore boxes the value of i by doing the following: Creating an object of type int in the heap Copying the value of i to the int object Returning the reference of the int object to oi to store as its reference
