The Hashtable class represents a collection of key-and-value pairs that are organized based on the hash code of the key. The key is used to access the items in the collection. Hashtable.ContainsValue(Object) Method is used to check whether the Hashtable contains a specific value or not.
public virtual bool ContainsValue(object value);
value: The value of type System.Object to locate in the Hashtable. The value can be null.
Return Type: This method returns true if the Hashtable contains an element with the specified value otherwise it returns false. The return type of this method is System.Boolean.
Below given are some examples to understand the implementation in a better way:
myTable contains the Value
myTable doesn't contain the Value
