Negative words and phrases such as not, you don t, you re not able to, and the like should rarely be used If you use such terminology frequently, you dilute the impact of the words If, on the other hand, you use them judiciously, you underscore your point, adding emphasis and urgency to your communications People don t like to read or respond to bad news In Two, we reviewed organizational structures that help you say no or deliver bad news as smoothly as possible Now let s examine negative words and phrases themselves and see if you can select alternatives that will more effectively generate the results you seek

We calculate the derivative of f (x) = Sin inverse functions The result is 1 d 1 = Sin (x) = 1 dx cos(Sin x)

// Demonstrate when constructors are called using System; // Create a base class class A { public A() { ConsoleWriteLine("Constructing A"); } } // Create a class derived from A class B : A { public B() {

11:

ConsoleWriteLine("Constructing B"); } }

// Create a class derived from B class C : B { public C() { ConsoleWriteLine("Constructing C"); } } class OrderOfConstruction { static void Main() { C c = new C(); } }

The output from this program is shown here:

As you can see, the constructors are called in order of derivation If you think about it, it makes sense that constructors are executed in order of derivation Because a base class has no knowledge of any derived class, any initialization it needs to perform is separate from and possibly prerequisite to any initialization performed by the derived class Therefore, it must be executed first

As you know, C# is a strongly typed language Aside from the standard conversions and automatic promotions that apply to its value types, type compatibility is strictly enforced Therefore, a reference variable for one class type cannot normally refer to an object of another class type For example, consider the following program that declares two classes that are identical in their composition:

= x)

// This program will not compile class X { int a; public X(int i) { a = i; } } class Y { int a; public Y(int i) { a = i; } } class IncompatibleRef { static void Main() {

Highlight good news instead of bad news by writing about what can occur, not what can t Consider the following two sentences:

Part I:

X x = new X(10); X x2; Y y = new Y(5); x2 = x; // OK, both of same type x2 = y; // Error, not of same type } }

Here, even though class X and class Y are physically the same, it is not possible to assign a reference of type Y to a variable of type X because they have different types Therefore, this line is incorrect because it causes a compile-time type mismatch:

1 1 x2

0 0 1 1 2 2 3 3 4 4 5 5 6 6 7 7 8 8 9

As the output shows, Main( ) suspends execution until both tsk and tsk2 terminate It is important to understand that in this program, the sequence in which tsk and tsk2 finish is not important relative to the calls to Wait( ) For example, if tsk2 completed first, the call to

Calculate the following derivatives:

M u l t i t h r e a d i n g , P a r t Tw o : E x p l o r i n g t h e Ta s k P a r a l l e l L i b r a r y a n d P L I N Q

tskWait( ) would still wait until tsk finished Then, the call to tsk2Wait( ) would execute and return immediately, since tsk2 was already done Although using two separate calls to Wait( ) works in this case, there is a simpler way: use WaitAll( ) This method waits on a group of tasks It will not return until all have finished Here is its simplest form: public static void WaitAll(params Task[ ] tasks) The tasks that you want to wait for are passed via tasks Because this is a params parameter, you can pass an array of Task objects or list of tasks separately Various exceptions are possible, including AggregateException To see WaitAll( ) in action, in the preceding program try replacing this sequence
