Important I ve found this to be the best way for developers to think of custom attributes: instances of classes that have been serialized to a byte stream that resides in metadata . Later, at runtime, an instance of the class can be constructed by deserializing the bytes contained in the metadata . In reality, what actually happens is that the compiler emits the information necessary to create an instance of the attribute class into metadata . Each constructor parameter is written out with a 1-byte type ID followed by the value . After serializing the constructor s parameters, the compiler emits each of the specified field and property values by writing out the field/property name followed by a 1-byte type ID and then the value . For arrays, the count of elements is saved first, followed by each individual element .

try { // Some code } catch { // Some exception handling code // Rethrow the caught exception throw; }

Defining an attribute class is useless by itself . Sure, you could define attribute classes all you want and apply instances of them all you want, but this would just cause additional metadata to be written out to the assembly the behavior of your application code wouldn t change . In 15, Enumerated Types and Bit Flags, you saw that applying the Flags attribute to an enumerated type altered the behavior of System.Enum s ToString and Format methods . The reason that these methods behave differently is that they check at runtime if the enumerated type that they re operating on has the Flags attribute metadata associated with it . Code can look for the presence of attributes by using a technology called reflection . I ll give some brief demonstrations of reflection here, but I ll discuss it fully in 23, Assembly Loading and Reflection . If you were the Microsoft employee responsible for implementing Enum s Format method, you would implement it like this:

The same performance issues with exceptions exist in C# as in Java. Throwing exceptions can be expensive and should not be used as a general flow control mechanism.

Supported Authentication Protocol MS-CHAP, CHAP, SPAP, PAP, MS-CHAP v2, and EAP MS-CHAP, CHAP, SPAP, PAP, and MS-CHAP v2 (with Windows NT 4.0 Service Pack 4 and later) EAP Unsupported Authentication Protocol

public static String Format(Type enumType, Object value, String format) { // Does the enumerated type have an instance of // the FlagsAttribute type applied to it if (enumType.IsDefined(typeof(FlagsAttribute), false)) { // Yes; execute code treating value as a bit flag enumerated type. ... } else { // No; execute code treating value as a normal enumerated type. ... } ... }

Configuring Remote Access Connections 10-13

This code calls Type s IsDefined method, effectively asking the system to look up the metadata for the enumerated type and see whether an instance of the FlagsAttribute class is associated with it . If IsDefined returns true, an instance of FlagsAttribute is associated with the enumerated type, and the Format method knows to treat the value as though it contained a set of bit flags . If IsDefined returns false, Format treats the value as a normal enumerated type .

Table 10-2

The java.lang.Throwable class is the root of the Java exception class hierarchy. Two classes derive directly from Throwable: java.lang.Exception and java.lang.Error. Derived from Exception is a class named java.lang.RuntimeException. The Exception, Error, and RuntimeException subclasses of Throwable are central to the Java classification of exceptions into the checked and unchecked categories. Unchecked exceptions are those derived from either the Error or RuntimeException class. The compiler makes no attempt to ensure that these exceptions are handled by the developer since they generally occur because of a run-time or program error that should be fixed. Checked exceptions are those that the compiler ensures are caught and handled within the code or are declared in the throws clause of the method declaration. Checked exceptions include all exceptions derived from java.lang.Exception, excluding RuntimeException and its subclasses. Because C# function members cannot declare exceptions, the compiler makes no attempt to ensure that exceptions are caught and handled correctly. All .NET exceptions can be considered to be unchecked exceptions in Java terminology. .NET takes a simpler approach to classifying exceptions based on whether it is a system or an application-related exception. This is merely a convention and is not enforced by the compiler or the runtime. The root of the exception hierarchy in .NET is System.Exception. System exceptions are represented by System.SystemException and application exceptions by System.ApplicationException, both of which are derived from System.Exception.
