value

The value to locate in the LinkedList. The value can be a null reference (Nothing in Visual Basic) for reference types.

This method performs a linear search; therefore, this method is an O(n) operation, where n is Count.

The following code example and output demonstrate the Contains method. The example creates an array of strings, then creates and populates a LinkedList by passing the array of strings to the constructor. Finally, the example uses the Contains method to test whether the list contains a particular string.

This code and output are part of a larger example provided for the LinkedList class.

// Create the link list.
string[] words =
    { "the", "fox", "jumped", "over", "the", "dog" };
LinkedList<string> sentence = new LinkedList<string>(words);
