MethodData Class

Contains information about a WMI method.


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

public class MethodData

The MethodData type exposes the following members.

Public propertyInParametersGets the input parameters to the method. Each parameter is described as a property in the object. If a parameter is both in and out, it appears in both the InParameters and OutParameters properties.
Public propertyNameGets the name of the method.
Public propertyOriginGets the name of the management class in which the method was first introduced in the class inheritance hierarchy.
Public propertyOutParametersGets the output parameters to the method. Each parameter is described as a property in the object. If a parameter is both in and out, it will appear in both the InParameters and OutParameters properties.
Public propertyQualifiersGets a collection of qualifiers defined in the method. Each element is of type QualifierData and contains information such as the qualifier name, value, and flavor.

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 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 methodToStringReturns a string that represents the current object. (Inherited from Object.)

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.
