In continuing with the ‘Refactorings for simplifying of the .NET 4.0 parallel computing development‘ thread, let’s review the additional refactoring for executing statements asynchronously called in the same manner – Execute Statement Asynchronously. The refactoring is available in two versions:
In C#, C++ and JavaScript languages, curly braces are used as block delimiters. A block allows multiple statements to be written inside. If a block contains a single statement, block delimiters, in most cases, are optional. For example, a single statement inside a loop does not require block delimiters:
A switch statement executes logic, dependent on the value of a given expression (parameter). The types of values a switch statement operates on can be boolean, enum, integral types, and strings. Each switch statement can contain any number of case statements, but no two case constants within the same switch statement can have the same value. Each case statement defines a value to compare against the original expression. You may also include a default label following all other case statements. If none of the other choices match, then the default choice is taken and its statements are executed. If there is no default label, control is transferred outside the switch.
Cause:
The else statement is redundant when it doesn’t contain any code, and can be safely removed to improve readability. The type of code issue is a dead code.
