成員函式會傳回輸入的 iterator,指派受控制序列中,或只是超出空序列結尾的第一個項目。
範例
// cliext_collection_adapter_begin.cpp
// compile with: /clr
#include <cliext/adapter>
#include <cliext/deque>
typedef cliext::collection_adapter<
System::Collections::ICollection> Mycoll;
int main()
{
cliext::deque<wchar_t> d1;
d1.push_back(L'a');
d1.push_back(L'b');
d1.push_back(L'c');
Mycoll c1(%d1);
// display initial contents " a b c"
for each (wchar_t elem in c1)
System::Console::Write(" {0}", elem);
System::Console::WriteLine();
// inspect first two items
Mycoll::iterator it = c1.begin();
System::Console::WriteLine("*begin() = {0}", *it);
System::Console::WriteLine("*++begin() = {0}", *++it);
return (0);
