Adds an element with the provided key and value to the IDictionary object.

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

Syntax

'Declaration
Sub Add ( _
    key As Object, _
    value As Object _
)

void Add(
    Object key,
    Object value
)

void Add(
    Object^ key, 
    Object^ value
)

abstract Add : 
        key:Object * 
        value:Object -> unit 

function Add(
    key : Object, 
    value : Object
)

Parameters

• key
  Type: System. . :: . .Object
  The Object to use as the key of the element to add.

• value
  Type: System. . :: . .Object
  The Object to use as the value of the element to add.

Remarks

You can also use the Item property to add new elements by setting the value of a key that does not exist in the dictionary (for example, myCollection["myNonexistentKey"] = myValue). However, if the specified key already exists in the dictionary, setting the Item property overwrites the old value. In contrast, the Add method does not modify existing elements.
