MethodDataCollection Class

Represents the set of methods available in the collection.


Namespace:  System.Management
Assembly:  System.Management (in System.Management.dll)

public class MethodDataCollection : ICollection, 

The MethodDataCollection type exposes the following members.

Public propertyCountGets the number of objects in the MethodDataCollection collection.
Public propertyIsSynchronizedGets a value that indicates whether the object is synchronized.
Public propertyItemGets the specified MethodData from the MethodDataCollection.
Public propertySyncRootGets the object to be used for synchronization.

Public methodAdd(String)Adds a MethodData to the MethodDataCollection. This overload will add a new method with no parameters to the collection.
Public methodAdd(String, ManagementBaseObject, ManagementBaseObject)Adds a MethodData to the MethodDataCollection. This overload will add a new method with the specified parameter objects to the collection.
Public methodCopyTo(Array, Int32)Copies the MethodDataCollection into an array.
Public methodCopyTo(MethodData[], Int32)Copies the MethodDataCollection to a specialized MethodData array.
Public methodEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetEnumeratorReturns an enumerator for the MethodDataCollection.
Public methodGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodRemoveRemoves a MethodData from the MethodDataCollection.
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

Public Extension MethodCast<TResult>()Overloaded. Casts the elements of an IEnumerable to the specified type. (Defined by Enumerable.)
Public Extension MethodCast<TResult>()Overloaded. (Defined by Enumerable.)
Public Extension MethodOfType<TResult>()Overloaded. Filters the elements of an IEnumerable based on a specified type. (Defined by Enumerable.)
Public Extension MethodOfType<TResult>()Overloaded. (Defined by Enumerable.)

Explicit interface implemetationPrivate methodIEnumerable.GetEnumeratorReturns an IEnumerator that iterates through the MethodDataCollection.

The following example lists information about the Win32_Process.Create method using the MethodData class. For more information on the Win32_Process class, see the Windows Management Instrumentation documentation in the MSDN Library at http://msdn.microsoft.com/library.

                foreach(PropertyData o in
