CString类:
用GetString(数组只读时用)和GetBuffer(向数组写数据时用,GetBuffer无参数)来获得CString内保存的数组,

下面是把CStringArray的函数说明复制下来的(原文,英文我看不明白,你自己看吧).

Construction

CStringArray Constructs an empty array for CString objects.

Bounds

GetCount Gets number of elements in this array.
GetSize Gets number of elements in this array.
GetUpperBound Returns the largest valid index.
SetSize Sets the number of elements to be contained in this array.

Operations

FreeExtra Frees all unused memory above the current upper bound.
RemoveAll Removes all the elements from this array.

Element Access

ElementAt Returns a temporary reference to the element pointer within the array.
GetAt Returns the value at a given index.
GetData Allows acce
