Chapter 12 Quick Reference

To	Do this
Create a fixed-size array of C++ built-in types.	Use a native C++ array.
Create a managed array of C++ built-in types.	Use the __gc keyword when creating the array. For example: int arr1 __gc[] = new int __gc[10];
Create an unmanaged array of .NET types.	Use the __nogc keyword when creating the array. For example: Int32 arr2 __nogc[22];
Iterate over the members of a managed array.	Either use the Count property with a loop, like this: int arr1 __gc[] = new int __gc[10]; for (int i=0; i<arr1->Count; i++) // do something or get an enumerator and use the MoveNext method and Current property, like this: IEnumerator* ie = sa->GetEnumerator(); while (ie->MoveNext()) Console::WriteLine(Sie->Current);
Create a dynamic array.	Use the ArrayList class.
Maintain a list of key/ value pairs.	Use the SortedList or Hashtable classes.
Maintain a list of strings.	Use the StringCollection class.
