Searches the specified one-dimensional Array, returning the index of the first occurrence of the specified object in the specified range.
[System.Runtime.ConstrainedExecution.ReliabilityContract(System.Runtime.ConstrainedExecution.Consistency.WillNotCorruptState, System.Runtime.ConstrainedExecution.Cer.MayFail)]
public static int IndexOf (Array array, object value, int startIndex, int count)
public static int IndexOf (Array array, object value, int startIndex, int count)
Parameters
Returns
A int containing the index of the first occurrence of value in array, within the range startIndex through startIndex + count- 1, 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-
count is less than zero.
-or-
startIndex + count is greater than array.GetLowerBound(0) + array.Length.
RankException array has more than one dimension.
Remarks
The elements are compared using object.Equals(object).
