Remarks

The MessagePart class corresponds to a Web Services Description Language (WSDL) <part> element enclosed by the <message> element, which is in turn enclosed by the <definitions> root element. For more information about WSDL, see the WSDL specification.

Properties

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)
Item[Int32]	Gets or sets the value of a MessagePart at the specified zero-based index.
Item[String]	Gets a MessagePart specified by its name.
List	Gets an IList containing the list of elements in the CollectionBase instance. (Inherited from CollectionBase)
Table	Gets an interface that implements the association of the keys and values in the ServiceDescriptionBaseCollection. (Inherited from ServiceDescriptionBaseCollection)

Methods

Add(MessagePart)	Adds the specified MessagePart to the end of the MessagePartCollection.
Clear()	Removes all objects from the CollectionBase instance. This method cannot be overridden. (Inherited from CollectionBase)
Contains(MessagePart)	Returns a value indicating whether the specified MessagePart is a member of the MessagePartCollection.
CopyTo(MessagePart[], Int32)	Copies the entire MessagePartCollection to a compatible one-dimensional array of type MessagePart, starting at the specified zero-based index of the target array.
Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetEnumerator()	Returns an enumerator that iterates through the CollectionBase instance. (Inherited from CollectionBase)
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetKey(Object)	Returns the name of the key associated with the value passed by reference. (Inherited from ServiceDescriptionBaseCollection)
GetType()	Gets the Type of the current instance. (Inherited from Object)
IndexOf(MessagePart)	Searches for the specified MessagePart and returns the zero-based index of the first occurrence within the collection.
Insert(Int32, MessagePart)	Adds the specified MessagePart to the MessagePartCollection at the specified zero-based index.
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
OnClear()	Clears the contents of the ServiceDescriptionBaseCollection instance. (Inherited from ServiceDescriptionBaseCollection)
OnClearComplete()	Performs additional custom processes after clearing the contents of the CollectionBase instance. (Inherited from CollectionBase)
OnInsert(Int32, Object)	Performs additional custom processes before inserting a new element into the CollectionBase instance. (Inherited from CollectionBase)
OnInsertComplete(Int32, Object)	Performs additional custom processes after inserting a new element into the ServiceDescriptionBaseCollection. (Inherited from ServiceDescriptionBaseCollection)
OnRemove(Int32, Object)	Removes an element from the ServiceDescriptionBaseCollection. (Inherited from ServiceDescriptionBaseCollection)
OnRemoveComplete(Int32, Object)	Performs additional custom processes after removing an element from the CollectionBase instance. (Inherited from CollectionBase)
OnSet(Int32, Object, Object)	Replaces one value with another within the ServiceDescriptionBaseCollection. (Inherited from ServiceDescriptionBaseCollection)
OnSetComplete(Int32, Object, Object)	Performs additional custom processes after setting a value in the CollectionBase instance. (Inherited from CollectionBase)
OnValidate(Object)	Performs additional custom processes when validating a value. (Inherited from CollectionBase)
Remove(MessagePart)	Removes the first occurrence of the specified MessagePart from the MessagePartCollection.
RemoveAt(Int32)	Removes the element at the specified index of the CollectionBase instance. This method is not overridable. (Inherited from CollectionBase)
SetParent(Object, Object)	Sets the parent object of the ServiceDescriptionBaseCollection instance. (Inherited from ServiceDescriptionBaseCollection)
ToString()	Returns a string that represents the current object. (Inherited from Object)

Explicit Interface Implementations

ICollection.CopyTo(Array, Int32)	Copies the entire CollectionBase to a compatible one-dimensional Array, starting at the specified index of the target array. (Inherited from CollectionBase)
ICollection.IsSynchronized	Gets a value indicating whether access to the CollectionBase is synchronized (thread safe). (Inherited from CollectionBase)
ICollection.SyncRoot	Gets an object that can be used to synchronize access to the CollectionBase. (Inherited from CollectionBase)
IList.Add(Object)	Adds an object to the end of the CollectionBase. (Inherited from CollectionBase)
IList.Contains(Object)	Determines whether the CollectionBase contains a specific element. (Inherited from CollectionBase)
IList.IndexOf(Object)	Searches for the specified Object and returns the zero-based index of the first occurrence within the entire CollectionBase. (Inherited from CollectionBase)
IList.Insert(Int32, Object)	Inserts an element into the CollectionBase at the specified index. (Inherited from CollectionBase)
IList.IsFixedSize	Gets a value indicating whether the CollectionBase has a fixed size. (Inherited from CollectionBase)
IList.IsReadOnly	Gets a value indicating whether the CollectionBase is read-only. (Inherited from CollectionBase)
IList.Item[Int32]	Gets or sets the element at the specified index. (Inherited from CollectionBase)
IList.Remove(Object)	Removes the first occurrence of a specific object from the CollectionBase. (Inherited from CollectionBase)

Extension Methods

Cast<TResult>(IEnumerable)	Casts the elements of an IEnumerable to the specified type.
OfType<TResult>(IEnumerable)	Filters the elements of an IEnumerable based on a specified type.
AsParallel(IEnumerable)	Enables parallelization of a query.
AsQueryable(IEnumerable)	Converts an IEnumerable to an IQueryable.
