Platform::Collections::Vector Class

2 out of 4 rated this helpful - Rate this topic

Represents a sequential collection of objects that can be individually accessed by index. The type of each object in the collection is specified by the specified template parameter. Allowed types are:

template <typename T, typename E>
   ref class Vector sealed;

Parameters

T: The type of the elements contained in the Vector object.
E: Specifies a binary predicate for testing equality with values of type T. The default value is std::equal_to<T>.

Remarks

Allowed types are:

integers
interface class ^
public ref class^
value struct
public enum class

The Vector class is the C++ concrete implementation of the Windows::Foundation::Collections::IVector interface.

If you attempt to use a Vector type in a public return value or parameter, compiler error C3986 will be raised. You can fix the error by changing the parameter or return value type to Windows::Foundation::Collections::IVector. For more information, see Collections (C++/CX).
