Definition

Overloads

Copies the entries in the specified NameValueCollection to the current NameValueCollection.

Add(String, String) Add(String, String) Add(String, String) Add(String, String)

Adds an entry with the specified name and value to the NameValueCollection.

Add(NameValueCollection) Add(NameValueCollection) Add(NameValueCollection) Add(NameValueCollection)

public:
 void Add(System::Collections::Specialized::NameValueCollection ^ c);
public void Add (System.Collections.Specialized.NameValueCollection c);
member this.Add : System.Collections.Specialized.NameValueCollection -> unit
Public Sub Add (c As NameValueCollection)

Parameters

Exceptions

Remarks

If a key in c already exists in the target NameValueCollection instance, the associated value in c is added to the existing comma-separated list of values associated with the same key in the target NameValueCollection instance.

If Count already equals the capacity, the capacity of the NameValueCollection is increased by automatically reallocating the internal array, and the existing elements are copied to the new array before the new element is added.

If Count is less than the capacity, this method is an O(1) operation. If the capacity needs to be increased to accommodate the new element, this method becomes an O(n) operation, where n is Count.
