您可以在 C++/CX 程式中任意使用標準 C-Style 陣列或std::array(雖然std::vector通常是比較好的選擇),但若是在中繼資料中所發行的任何 API 中,您必須根據 C-Style 陣列或向量的用途,將其轉換為Platform::Array或Platform::WriteOnlyArray類型。Platform::Array類型的效率及功能都不如std::vector,因此一般來說,...
Array 類別並非 System.Collections 命名空間的一部分。然而它仍然是集合,因為它是以 IList 介面為基礎。Array 物件的陣序 (Rank) 是 Array 中的維度 (Dimension) 數目。Array 可以擁有一個或多個順序。Array 的下限為其第一個元素的索引。Array 可以具有任何下限。它預設具有零的下限,但在使用 CreateInstance 來...
这种转换的意义不大,如果转换完之后再强行用Array.ConvertAll方法来进行数据类型的转换,很有可能会出现诸如Unable to cast object of type 'System.String' to type 'System.Int32'.的错误,这是因为ArrayList本身成员就可以不是单一类型。 数组的打印 Array的打印 对于Array的打印,我找到了四种方式,如下: 调用Array...

While this type is quite versatile, you can think of it as a length-prefixed Unicode UTF-16 string pointer. The default Marshaller knows how to copy BSTRs and how to make them cross COM or C-interface function boundaries. An interesting and detailed description on BSTR semantics can be ...
因為索引是以零起始,因此大小大於最大索引 1。 呼叫此方法會產生與CArray::GetCount方法相同的結果。 範例 C++ CArray<CPoint, CPoint> myArray;// Add elements to the array.for(inti =0; i <10; i++) myArray.Add(CPoint(i,2* i));// Modify all the points in the array.for(inti =0;...
