1. 遍历

        for（auto i : MyTArray){i->   or    *i}

2 找到最大值的索引

int32 IndexOfMax(TArray<float> Array)
{int32 HighestIndex = 0;for (int32 Counter = 0; Counter < Array.Num(); ++Counter){if (Counter > 0){if ([=]() { return (Array[Counter] > Array[HighestIndex]); }()){HighestIndex = Counter;}}}return HighestIndex;
}
