public virtual void Add(
	string name,
	string value
)

Parameters

name

The String key of the entry to add. The key can be null.

value
Type: System.String

The String value of the entry to add. The value can be null.

ExceptionCondition
NotSupportedException

The collection is read-only.

If the specified key already exists in the target NameValueCollection instance, the specified value 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.
