char senseChar, ringChar = 'e'; declares two character variables senseChar and ringChar, with the second of these variables being initialized to contain the character e There is a Boolean data type known as boolean Variables of this type can hold either the value true or the value false Thus, boolean loopSensor, pollSensor = true; declares the Boolean variables loopSensor and pollSensor and sets the second of these to the value true All the primitive data types that are provided in Java are associated with operators which are used to build up expressions Binary arithmetic operators can be used both with floats and with the various integer types A list of these is shown in Table 41 The only operator which needs a little explanation is the % operator which is applied to data that is of an integer type It returns the value which is the remainder when its left operand is divided by its right operand For example, the value of: 34 % 5 is 4 since this is the remainder when 34 is divided by 5 This is similar to modulo arithmetic There is also a class of operators known as arithmetic assignment operators These mainly carry out some arithmetic operation such as addition and then assign the result to one of the variables used in the expression containing the operator These are shown in Table 42

As Output 1512 demonstrates, the value of _Count for the thread executing Main() is never decremented by the thread executing Decrement() Since _Count is decorated by the THReadStaticAttribute, the thread running Main() and the thread running Decrement() are operating on entirely different instances of _Count There is one important caveat to the ThreadStaticAttribute If the value of _Count is assigned during declarationprivate int _Count = 42 , for example then only the thread static instance associated with the thread running the constructor will be initialized In Listing 1515, only the thread executing Main() will have a thread local storage variable of _Count that is initialized The value of _Count that Decrement() decrements will never be initialized Similarly, if a constructor initializes a thread local storage field, only the constructor calling thread will have an initialized thread local storage instance For this reason, it is a good practice to initialize a thread local storage field within the method that is initially called by each thread The decision to use thread local storage requires some degree of cost-benefit analysis For example, consider using thread local storage for a database connection Depending on the database management system, database connections are relatively expensive, so creating a connection for every thread could be costly Similarly, locking a connection so that all database calls are synchronized places a significantly lower ceiling on scalability Each pattern has its costs and benefits,

each delegate invocation list, using the GetInvocationList() method, to retrieve each individual return value Similarly, delegate types that use ref and out parameters need special consideration

There are two key problems with the delegates as you have used them so far in this chapter To overcome these issues, C# uses the keyword event In this section, you will see why you would use events, and how they work

and the correct choice depends largely on the individual implementation Another reason to use ThreadStatic is to make commonly needed context information available to other methods without explicitly passing the data via parameters If multiple methods in the call stack require user security information, for example, you can pass the data using thread local storage fields instead of as parameters This keeps APIs cleaner while still making the information available to methods in a thread-safe manner

Why Events This chapter and the preceding one covered all you need to know about how delegates work However, weaknesses in the delegate structure may inadvertently allow the programmer to introduce a bug The issues relate to encapsulation that neither the subscription nor the publication of events can sufficiently control

As demonstrated earlier, it is possible to assign one delegate to another using the assignment operator Unfortunately, this capability introduces a common source for bugs Consider Listing 1312

The last synchronization method to point out is the MethodImplAttribute Used in conjunction with the MethodImplOptionsSynchronized method, this attribute marks a method as synchronized so that only one thread can execute the method at a time In the current implementation, this causes the JIT to treat the method as though it was surrounded by lock(this) Such an implementation means that, in fact, the method and all other methods on the same class, decorated with the same attribute and enum, are synchronized, not just each method relative to itself In other words, given two or more methods on the same class decorated with the attribute, only one of them will be able to execute at a time and the one executing will block all calls by other threads to itself or to any other method in the class with the same decoration

class Program { public static void Main() { Thermostat thermostat = new Thermostat(); Heater heater = new Heater(60); Cooler cooler = new Cooler(80); string temperature; // Note: Use new ThermostatTemperatureChangeHandler( // coolerOnTemperatureChanged) if C# 10 thermostatOnTemperatureChange = heaterOnTemperatureChanged; // Bug: assignment operator overrides // previous assignment thermostatOnTemperatureChange = coolerOnTemperatureChanged;
