Dissecting a C# Application: Inside SharpDevelop

Study complicated . internet programming strategies through getting an insiders' examine a whole program! SharpDevelop is an entire built-in improvement setting, written in C#. It contains the entire complex positive factors that programmers count on from a contemporary IDE and, in fact, enforcing those beneficial properties has required a few complex programming innovations.

Example text

A local variable is defined by specifying a type name and a declarator that specifies the variable name and an optional initial value, as in: int a; int b = 1; but it is also possible for a local variable declaration to include multiple declarators. The declarations of a and b can be rewritten as: int a, b = 1; A variable shall be assigned before its value can be obtained. The example 22 8 Language overview class Test { static void Main() { int a; int b = 1; int c = a + b; // error, a not yet assigned … } } results in a compile-time error because it attempts to use the variable a before it is assigned a value.

The WriteLine method provides several overloaded methods for the common cases in which a small number of arguments are passed, and one method that uses a parameter array. 4 Automatic memory management Manual memory management requires developers to manage the allocation and de-allocation of blocks of memory. Manual memory management can be both time-consuming and difficult. In C#, automatic memory management is provided so that developers are freed from this burdensome task. In the vast majority of cases, automatic memory management increases code quality and enhances developer productivity without negatively impacting either expressiveness or performance.

The program does not use #include to import program text. Dependencies among programs are handled symbolically rather than textually. This approach eliminates barriers between applications written using multiple languages. For example, the Console class need not be written in C#. 2 Types C# supports two kinds of types: value types and reference types. , char, int, and float), enum types, and struct types. Reference types include class types, interface types, delegate types, and array types. Value types differ from reference types in that variables of the value types directly contain their data, whereas variables of the reference types store references to objects.
