Find Method

Array.Find Generic Method

Note: This method is new in the .NET Framework version 2.0.

Searches for an element that matches the conditions defined by the specified predicate, and returns the first occurrence within the entire Array.

Namespace: System
Assembly: mscorlib (in mscorlib.dll)

generic<typename T>
static T Find (
	array<T>^ array, 
	Predicate<T>^ match
J# supports the use of generic types and methods, but not the declaration of new ones.
JScript does not support generic types and methods.

Type Parameters


The type of the elements of the array.



The one-dimensional, zero-based Array to search.


The Predicate that defines the conditions of the element to search for.

Return Value

The first element that matches the conditions defined by the specified predicate, if found; otherwise, the default value for type T.

Exception typeCondition


array is a null reference (Nothing in Visual Basic).


match is a null reference (Nothing in Visual Basic).

The Predicate 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 array are individually passed to the Predicate, moving forward in the Array, starting with the first element and ending with the last element. Processing is stopped when a match is found.

This method is an O(n) operation, where n is the Length of array.

The following code example uses a Predicate delegate with the Find generic method to search an array of Point structures. The method the delegate represents, ProductGT10, returns true if the product of the X and Y fields is greater than 100,000. The Find method calls the delegate for each element of the array, returning the first point that meets the test condition.


Visual Basic and C# users do not need to create the delegate explicitly, or to specify the type argument of the generic method. The compilers determine the necessary types from the method arguments you supply.

No code example is currently available or this language may not be supported.
