## IList class


Interface of indexed container of elements. Objects of this class should only be allocated using [System::MakeObject()](../../system/makeobject/) function. Never create instance of this type on stack or using operator new, as it will result in runtime errors and/or assertion faults. Always wrap this class into [System::SmartPtr](../../system/smartptr/) pointer and use this pointer to pass it to functions as argument.

```cpp
template<typename T>class IList : public System::Collections::Generic::ICollection<T>
```


| Parameter | Description |
| --- | --- |
| T | Element type. |
