    1. C# Soup To Nuts: Arrays and Collections William J. Steele MSDN Developer Evangelist Microsoft Corporation http://blogs.msdn.com/wsteele

    2. What We Will Cover Arrays Creating an array Array types Single-dimensional Two-dimensional Multidimensional Jagged Collection classes foreach statement Generic lists

    3. Arrays Similar to other languages Zero-based [] After type (not name) Simple example (array of integers): int[] names;

    4. Demonstration One Creating and Using Arrays

    5. Countless Dimensions Single-dimensional type[] name; Two-dimensional type[,] name; Multidimensional type[,,] name; Jagged (array of arrays) type[][] name;

    6. Demonstration Two Multidimensional Arrays

    7. Collection Classes System.Collections ArrayList and List Variable size arrays Always single-dimensional .Add method Advanced functionality Implements IList interface Sorting Comparing

    8. Demonstration Three Collection Classes

    9. Generic Collection Classes System.Collections.Generic Just like collections, except: Strongly typed Implements IList generic interface Sometimes faster Read as list of <Type> Example: List<int> = new List<int>();

    10. Demonstration Four Generic Lists

    11. Summary Arrays Creating an array Array types Single-dimensional Two-dimensional Multidimensional Jagged Collection classes foreach statement Generic lists

    12. Next Week: Creating and Manipulating Strings Microsoft Visual C# .NET is the newest programming language from Microsoft. So far in this series, we've been exploring the basics of C# and Microsoft Visual C# 2005 Express Edition. In this webcast, we will learn about strings, and we will see how to create and manipulate them using basic operators, in addition to the StringBuilder class.
