Adds the specified System.Web.Services.Description.MessagePart to the System.Web.Services.Description.MessagePartCollection at the specified zero-based index.
- index
- The zero-based index at which to insert the messagePart parameter.
- messagePart
- The System.Web.Services.Description.MessagePart to add to the collection.
If the number of items in the collection already equals the collection's capacity, the capacity is doubled by automatically reallocating the internal array before the new element is inserted.
If the index parameter is equal to CollectionBase.Count, the messagePart parameter is added to the end of the System.Web.Services.Description.MessagePartCollection.
The elements after the insertion point move down to accommodate the new element.
