This method(comes under
System.Collections namespace) is used to check whether a specified element is present is Stack or not. Internally this method checks for equality by calling the
Object.Equals method. Also, it performs a
linear search, therefore, this method is an
O(n) operation, where n is Count.
Syntax:
public virtual bool Contains (object obj);
Here,
obj is the object to locate in the Stack. The value can be
null.
Return Value: It returns
true, if
obj is found in the Stack otherwise returns
false.
Below programs illustrate the use of above-discussed method:
