OperationCollection Class

Represents a collection of instances of the Operation class. This class cannot be inherited.

Namespace:  System.Web.Services.Description
Assembly:  System.Web.Services (in System.Web.Services.dll)

public sealed class OperationCollection : ServiceDescriptionBaseCollection

The OperationCollection type exposes the following members.

  NameDescription
Public propertyCapacityGets or sets the number of elements that the CollectionBase can contain. (Inherited from CollectionBase.)
Public propertyCountGets the number of elements contained in the CollectionBase instance. This property cannot be overridden. (Inherited from CollectionBase.)
Public propertyItemGets or sets the value of an Operation at the specified zero-based index.

  NameDescription
Public methodAddAdds the specified Operation to the end of the OperationCollection.
Public methodClearRemoves all objects from the CollectionBase instance. This method cannot be overridden. (Inherited from CollectionBase.)
Public methodContainsReturns a value indicating whether the specified Operation is a member of the OperationCollection.
Public methodCopyToCopies the entire OperationCollection to a compatible one-dimensional array of type Operation, starting at the specified zero-based index of the target array.
Public methodEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Public methodGetEnumeratorReturns an enumerator that iterates through the CollectionBase instance. (Inherited from CollectionBase.)
Public methodGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodIndexOfSearches for the specified Operation and returns the zero-based index of the first occurrence within the collection.
Public methodInsertAdds the specified Operation to the OperationCollection at the specified zero-based index.
Public methodRemoveRemoves the first occurrence of the specified Operation from the OperationCollection.
Public methodRemoveAtRemoves the element at the specified index of the CollectionBase instance. This method is not overridable. (Inherited from CollectionBase.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

  NameDescription
Explicit interface implemetationPrivate methodICollection.CopyToCopies the entire CollectionBase to a compatible one-dimensional Array, starting at the specified index of the target array. (Inherited from CollectionBase.)
Explicit interface implemetationPrivate propertyICollection.IsSynchronizedGets a value indicating whether access to the CollectionBase is synchronized (thread safe). (Inherited from CollectionBase.)
Explicit interface implemetationPrivate propertyICollection.SyncRootGets an object that can be used to synchronize access to the CollectionBase. (Inherited from CollectionBase.)
Explicit interface implemetationPrivate methodIList.AddAdds an object to the end of the CollectionBase. (Inherited from CollectionBase.)
Explicit interface implemetationPrivate methodIList.ContainsDetermines whether the CollectionBase contains a specific element. (Inherited from CollectionBase.)
Explicit interface implemetationPrivate methodIList.IndexOfSearches for the specified Object and returns the zero-based index of the first occurrence within the entire CollectionBase. (Inherited from CollectionBase.)
Explicit interface implemetationPrivate methodIList.InsertInserts an element into the CollectionBase at the specified index. (Inherited from CollectionBase.)
Explicit interface implemetationPrivate propertyIList.IsFixedSizeGets a value indicating whether the CollectionBase has a fixed size. (Inherited from CollectionBase.)
Explicit interface implemetationPrivate propertyIList.IsReadOnlyGets a value indicating whether the CollectionBase is read-only. (Inherited from CollectionBase.)
Explicit interface implemetationPrivate propertyIList.ItemGets or sets the element at the specified index. (Inherited from CollectionBase.)
Explicit interface implemetationPrivate methodIList.RemoveRemoves the first occurrence of a specific object from the CollectionBase. (Inherited from CollectionBase.)

The Operation class corresponds to the Web Services Description Language (WSDL) <operation> element enclosed by the <portType> element. For more information about WSDL, see the specification at http://www.w3.org/TR/wsdl/.

The following example demonstrates the use of the properties and methods exposed by the OperationCollection class.

using System.Web.Services;
using System.Xml;
using System.Web.Services.Description;

class MyOperationCollectionSample

   public static void Main()
