Initializes a new instance of the InvokeMethodOptions class for an invoke operation.

Overloads

InvokeMethodOptions()

Initializes a new instance of the InvokeMethodOptions class for the InvokeMethod(String, Object[]) operation, using default values. This is the parameterless constructor.
InvokeMethodOptions(ManagementNamedValueCollection, TimeSpan)

Initializes a new instance of the InvokeMethodOptions class for an invoke operation using the specified values.

InvokeMethodOptions()

Source:
ManagementOptions.cs
Source:
ManagementOptions.cs

Initializes a new instance of the InvokeMethodOptions class for the InvokeMethod(String, Object[]) operation, using default values. This is the parameterless constructor.

public:
 InvokeMethodOptions();
public InvokeMethodOptions ();
Public Sub New ()

Examples

The following example invokes the Win32_Process::Create method to start a new process of Calc.exe. The parameterless constructor of the InvokeMethodOptions class is used.

using System;
using System.Management;

// This sample demonstrates invoking
// a WMI method using parameter objects
public class InvokeMethod
{
    public static void Main()
    {

        // Get the object on which the method will be invoked
        ManagementClass processClass =
            new ManagementClass("Win32_Process");

        // Get an input parameters object for this method
        ManagementBaseObject inParams =
            processClass.GetMethodParameters("Create");

        // Fill in input parameter values
        inParams["CommandLine"] = "calc.exe";

        // Method Options
        InvokeMethodOptions methodOptions = new
            InvokeMethodOptions();
        methodOptions.Timeout =
            System.TimeSpan.MaxValue;

        // Execute the method
        ManagementBaseObject outParams =
            processClass.InvokeMethod("Create",
            inParams, methodOptions);

        // Display results
        // Note: The return code of the method is
        // provided in the "returnValue" property
        // of the outParams object
        Console.WriteLine(
            "Creation of calculator process returned: "
            + outParams["returnValue"]);
        Console.WriteLine("Process ID: "
            + outParams["processId"]);
    }
}

Applies to

InvokeMethodOptions(ManagementNamedValueCollection, TimeSpan)

Source:
ManagementOptions.cs
Source:
ManagementOptions.cs

Initializes a new instance of the InvokeMethodOptions class for an invoke operation using the specified values.

public:
 InvokeMethodOptions(System::Management::ManagementNamedValueCollection ^ context, TimeSpan timeout);
public InvokeMethodOptions (System.Management.ManagementNamedValueCollection context, TimeSpan timeout);
new System.Management.InvokeMethodOptions : System.Management.ManagementNamedValueCollection * TimeSpan -> System.Management.InvokeMethodOptions
Public Sub New (context As ManagementNamedValueCollection, timeout As TimeSpan)

Parameters

context
ManagementNamedValueCollection

A provider-specific, named-value pairs object to be passed through to the provider.

timeout
TimeSpan

The length of time to let the operation perform before it times out. The default value is TimeSpan.MaxValue. Setting this parameter will invoke the operation semisynchronously.

Examples

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.

using System;
using System.Management;

// This sample demonstrates invoking
// a WMI method using parameter objects
public class InvokeMethod
{
    public static void Main()
    {

        // Get the object on which the method will be invoked
        ManagementClass processClass =
            new ManagementClass("Win32_Process");

        // Get an input parameters object for this method
        ManagementBaseObject inParams =
            processClass.GetMethodParameters("Create");

        // Fill in input parameter values
        inParams["CommandLine"] = "calc.exe";

        // Method Options
        InvokeMethodOptions methodOptions = new
            InvokeMethodOptions(null,
            System.TimeSpan.MaxValue);

        // Execute the method
        ManagementBaseObject outParams =
            processClass.InvokeMethod("Create",
            inParams, methodOptions);

        // Display results
        // Note: The return code of the method is
        // provided in the "returnValue" property
        // of the outParams object
        Console.WriteLine(
            "Creation of calculator process returned: "
            + outParams["returnValue"]);
        Console.WriteLine("Process ID: "
            + outParams["processId"]);
