Parameters

value

The object to locate in the current instance.

Returns

A int that specifies the index of the first occurrence of value in the current instance, if found; otherwise, -1.

Note: This provides the caller with a standard code for a failed search.

Remarks

Note: This method is implemented to support the IList interface.

Operation

As described above.

This method uses Array.IndexOf(Array, object) to search the current instance for value .

Note: For the default implementation, this method performs a linear search. On average, this is an O(n/2) operation, where n is count. The longest search is an O(n) operation.
