Searches the specified one-dimensional Array, returning the index of the first occurrence of the specified object between the specified index and the last element.
[System.Runtime.ConstrainedExecution.ReliabilityContract(System.Runtime.ConstrainedExecution.Consistency.WillNotCorruptState, System.Runtime.ConstrainedExecution.Cer.MayFail)]
public static int IndexOf (Array array, object value, int startIndex)
public static int IndexOf (Array array, object value, int startIndex)
Parameters
Returns
A int containing the index of the first occurrence of value in array, within the range startIndex through the last element of array, if found; otherwise, array.GetLowerBound(0) - 1.Note: For a vector, if value is not found, the return value will be -1. This provides the caller with a standard code for the failed search.
Exceptions
Type Reason ArgumentNullException array is null. ArgumentOutOfRangeException startIndex is less than array.GetLowerBound(0) or greater than array.GetLowerBound(0) + array.Length. RankException array has more than one dimension.
Remarks
This version of Array.IndexOf(Array, object) is equivalent to Array.IndexOf(Array, object) (array, value , startIndex, (array.Length - startIndex+array.GetLowerBound(0))).
The elements are compared using object.Equals(object).
