|---|---|---|
![]() | AllKeys | Gets a string array containing all the keys (cookie names) in the cookie collection. |
![]() | Count | Gets the number of key/value pairs contained in the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase.) |
![]() | IsReadOnly | Gets or sets a value indicating whether the NameObjectCollectionBase instance is read-only. (Inherited from NameObjectCollectionBase.) |
![]() | Item[Int32] | Gets the cookie with the specified numerical index from the cookie collection. |
![]() | Item[String] | Gets the cookie with the specified name from the cookie collection. |
![]() | Keys | Gets a NameObjectCollectionBase::KeysCollection instance that contains all the keys in the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase.) |
| Name | Description | |
|---|---|---|
![]() | Add | Adds the specified cookie to the cookie collection. |
![]() | BaseAdd | Adds an entry with the specified key and value into the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase.) |
![]() | BaseClear | Removes all entries from the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase.) |

![]() | BaseGet(String) | Gets the value of the first entry with the specified key from the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase.) |
![]() | BaseGetAllKeys | Returns a String array that contains all the keys in the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase.) |
![]() | BaseGetAllValues() | Returns an Object array that contains all the values in the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase.) |
![]() | BaseGetAllValues(Type) | Returns an array of the specified type that contains all the values in the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase.) |
![]() | BaseGetKey | Gets the key of the entry at the specified index of the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase.) |
![]() | BaseHasKeys | Gets a value indicating whether the NameObjectCollectionBase instance contains entries whose keys are not nullptr. (Inherited from NameObjectCollectionBase.) |
![]() | BaseRemove | Removes the entries with the specified key from the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase.) |
![]() | BaseRemoveAt | Removes the entry at the specified index of the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase.) |
![]() | BaseSet(Int32, Object) | Sets the value of the entry at the specified index of the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase.) |
![]() | BaseSet(String, Object) | Sets the value of the first entry with the specified key in the NameObjectCollectionBase instance, if found; otherwise, adds an entry with the specified key and value into the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase.) |
![]() | Clear | Clears all cookies from the cookie collection. |
![]() | CopyTo | Copies members of the cookie collection to an Array beginning at the specified index of the array. |
![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | Get(Int32) | Returns the HttpCookie item with the specified index from the cookie collection. |
![]() | Get(String) | Returns the cookie with the specified name from the cookie collection. |
![]() | GetEnumerator | Returns an enumerator that iterates through the NameObjectCollectionBase. (Inherited from NameObjectCollectionBase.) |
![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() | GetKey | Returns the key (name) of the cookie at the specified numerical index. |
![]() | GetObjectData | Implements the ISerializable interface and returns the data needed to serialize the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | OnDeserialization | Implements the ISerializable interface and raises the deserialization event when the deserialization is complete. (Inherited from NameObjectCollectionBase.) |
![]() | Remove | Removes the cookie with the specified name from the collection. |
![]() | Set | Updates the value of an existing cookie in a cookie collection. |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
| Name | Description | |
|---|---|---|
![]() ![]() | ICollection::CopyTo | Copies the entire NameObjectCollectionBase to a compatible one-dimensional Array, starting at the specified index of the target array. (Inherited from NameObjectCollectionBase.) |
![]() ![]() | ICollection::IsSynchronized | Gets a value indicating whether access to the NameObjectCollectionBase object is synchronized (thread safe). (Inherited from NameObjectCollectionBase.) |
![]() ![]() | ICollection::SyncRoot | Gets an object that can be used to synchronize access to the NameObjectCollectionBase object. (Inherited from NameObjectCollectionBase.) |
The following code example demonstrates how to read cookies using the Cookies property of the HttpRequest object and write cookies using the Cookies property of the HttpResponse object. Both properties return HttpCookieCollection objects. If either of two cookies named userName and lastVisit are not in the HTTP request, then they are created in the HTTP response. If the two cookies exist, the properties of the cookies are displayed.
