Parameters

value

The object to locate in current instance.

startIndex

A int that specifies the index at which to begin searching. This value is greater than or equal to zero, and less than the ArrayList.Count of the current instance.

count

A int that specifies the number of elements to search. This value is between 0 and the ArrayList.Count of the current instance minus startIndex , inclusive.

Returns

A int that specifies the index of the first occurrence of value in the current instance, within the range startIndex to startIndex + count - 1, if found; otherwise, -1.

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

Exceptions

Type	Reason
ArgumentOutOfRangeException	startIndex>= ArrayList.Count of the current instance. -or- count < 0. -or- count >ArrayList.Count of the current instance - startIndex.

Remarks

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.

Requirements

Namespace: System.Collections
Assembly: mscorlib (in mscorlib.dll)
Assembly Versions: 1.0.5000.0, 2.0.0.0
