- startIndex
- Type:
SystemInt32
The zero-based starting index of the search.
- match
- Type:
SystemPredicate
T
The PredicateT delegate that defines the conditions of the element to search for.
Return Value
Type: SystemInt32The zero-based index of the first occurrence of an element that matches the conditions defined by match, if found; otherwise, –1.
| Exception | Condition |
|---|---|
| ArgumentNullException | match is . |
| ArgumentOutOfRangeException | startIndex is outside the range of valid indexes for the ListT. |
The ListT is searched forward starting at startIndex and ending at the last element.
The PredicateT is a delegate to a method that returns true if the object passed to it matches the conditions defined in the delegate. The elements of the current ListT are individually passed to the PredicateT delegate.
This method performs a linear search; therefore, this method is an O(n) operation, where n is the number of elements from startIndex to the end of the ListT.
