InvokeMethodOptions Constructor (ManagementNamedValueCollection, TimeSpan)

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

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

public InvokeMethodOptions (
	ManagementNamedValueCollection context,
	TimeSpan timeout
)
public InvokeMethodOptions (
	ManagementNamedValueCollection context, 
	TimeSpan timeout
)
public function InvokeMethodOptions (
	context : ManagementNamedValueCollection, 
	timeout : TimeSpan
)

Parameters

context

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

timeout

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

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"]);
    }
}
