| OnRemoveComplete | Performs additional custom processes after removing an element from the CollectionBase instance. (Inherited from CollectionBase.) |
| OnSet | Performs additional custom processes before setting a value in the CollectionBase instance. (Inherited from CollectionBase.) |
| OnSetComplete | Performs additional custom processes after setting a value in the CollectionBase instance. (Inherited from CollectionBase.) |
| OnValidate | Performs additional custom processes when validating a value. (Inherited from CollectionBase.) |
| Remove |
Removes the header from the collection by the given name.
|
| RemoveAt |
Removes the header from the collection at the given zero-based index.
|

 | Capacity | Gets or sets the number of elements that the CollectionBase can contain. (Inherited from CollectionBase.) |
| Count | Gets the number of elements contained in the CollectionBase instance. This property cannot be overridden. (Inherited from CollectionBase.) |
 | InnerList | Gets an ArrayList containing the list of elements in the CollectionBase instance. (Inherited from CollectionBase.) |
| ItemInt32 |
Gets or sets the Header object in the collection at the specified zero-based index.
|

Remarks
This collection can be used to examine, modify, add or remove headers to the mail message or its
individual parts (such as attachments).
For mail messages, this collection is available through the MailMessage.Headers.
For individual MIME parts, the developer can access headers via MimePart.Headers property.
Attachment and TextBodyPart objects also support MimePart.Headers property.
To get the headers section of the message as string, use MailMessage.RawHeader property. MimePart class also supports such property. Please note that RawHeader properties will return empty string if the source of the message is not available (this is common when you're composing a new message rather than examining an existing one).
Examples
The example is available in Header class overview.
