Copies the entries in the specified System.Collections.Specialized.NameValueCollection to the current System.Collections.Specialized.NameValueCollection.
Syntax
Parameters
- c
Exceptions
Type Reason NotSupportedException The current instance is read-only. ArgumentNullException c is null.
Remarks
If a key in c already exists in the target System.Collections.Specialized.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 System.Collections.Specialized.NameValueCollection instance.
If NameObjectCollectionBase.Count already equals the capacity, the capacity of the System.Collections.Specialized.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 NameObjectCollectionBase.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 NameObjectCollectionBase.Count.
