List<T>::FindIndex Method (Int32, Predicate<T>)
Searches for an element that matches the conditions defined by the specified predicate, and returns the zero-based index of the first occurrence within the range of elements in the List<T> that extends from the specified index to the last element.
Assembly: mscorlib (in mscorlib.dll)
- Type: System::Int32
The zero-based starting index of the search.
Return ValueType: System::Int32
The zero-based index of the first occurrence of an element that matches the conditions defined by match, if found; otherwise, –1.
The List<T> is searched forward starting at startIndex and ending at the last element.
The Predicate<T> 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 List<T> are individually passed to the Predicate<T> 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 List<T>.
