- array
- Type: T[]
The one-dimensional, zero-based Array to search. - startIndex
- Type: System.Int32
The zero-based starting index of the backward search. - count
- Type: System.Int32
The number of elements in the section to search. - match
- Type: System.Predicate(T)
The Predicate(T) that defines the conditions of the element to search for.
- T
- The type of the elements of the array.
Type: Int32
The zero-based index of the last occurrence of an element that matches the conditions defined by match, if found; otherwise, –1.
In Visual Basic and C#, you can call this method as an instance method on any object of type . When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).
