```cpp
int System::Collections::Generic::List<T>::FindIndex(int startIndex, int count, System::Predicate<T> match)
```


| Parameter | Type | Description |

| startIndex | int | [Index](../../../system/index/) to start search from. |
| count | int | Number of elements to look through. |
| match | System::Predicate\<T\> | [Predicate](../../../system/predicate/) to check elements with. |

### ReturnValue

[Index](../../../system/index/) of matching element or -1 if not found.
