keyFrame

The QuaternionKeyFrame to locate in the collection.

Valeur de retour

The zero-based index of the first occurrence of keyFrame within the entire collection, if found; otherwise, -1.

The collection is searched forward starting at the first key frame and ending at the last key frame.

This method performs a linear search; therefore, the average execution time is proportional to Count. That is, this method is an O(n) operation, where n is Count.

This method determines equality by calling Object.Equals.
