Object-oriented Programming in C#
Introduction to C#
Commands and Control Structures

On this page we discuss control structures for selection and iteration. As usual, we concentrate on the differences between C an C#.

Almost all control structures in C can be used the same way in C#

  • Similarities

    • Expression statements, such as a = a + 5;

    • Blocks, such as {a = 5; b = a;}

    • if, if-else, switch, for, while, do-while, return, break, continue, and goto in C# are all similar to C

  • Differences

    • The C# foreach loop provides for easy traversal of all elements in a collection

    • try-catch-finally and throw in C# are related to exception handling

    • Some more specialized statements have been added: checked, unchecked, using, lock and yield.
