InvokeMethodOptions Class

Specifies options for invoking a management method.


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

Public Class InvokeMethodOptions _
	Inherits ManagementOptions

The InvokeMethodOptions type exposes the following members.

Public methodInvokeMethodOptionsInitializes a new instance of the InvokeMethodOptions class for the InvokeMethod(String, Object()) operation, using default values. This is the default constructor.
Public methodInvokeMethodOptions(ManagementNamedValueCollection, TimeSpan)Initializes a new instance of the InvokeMethodOptions class for an invoke operation using the specified values.

Public propertyContextGets or sets a WMI context object. This is a name-value pairs list to be passed through to a WMI provider that supports context information for customized operation. (Inherited from ManagementOptions.)
Public propertyTimeoutGets or sets the time-out to apply to the operation. Note that for operations that return collections, this time-out applies to the enumeration through the resulting collection, not the operation itself (the ReturnImmediately property is used for the latter). This property is used to indicate that the operation should be performed semi-synchronously. (Inherited from ManagementOptions.)

Public methodCloneReturns a copy of the object. (Overrides ManagementOptions.Clone.)
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 invokes the Win32_Process::Create method to start a new process of Calc.exe. The InvokeMethodOptions class is used to invoke the method.
