InvokeMethodOptions()

Sumber:

ManagementOptions.cs

Menginisialisasi instans InvokeMethodOptions baru kelas untuk InvokeMethod(String, Object[]) operasi, menggunakan nilai default. Ini adalah konstruktor tanpa parameter.

public:
 InvokeMethodOptions();

public InvokeMethodOptions ();

Public Sub New ()

Contoh

Contoh berikut memanggil metode Win32_Process::Create untuk memulai proses baru Calc.exe. Konstruktor tanpa parameter dari InvokeMethodOptions kelas digunakan.

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"]);

InvokeMethodOptions(ManagementNamedValueCollection, TimeSpan)

Sumber:

ManagementOptions.cs

Menginisialisasi instans InvokeMethodOptions baru kelas untuk operasi pemanggilan menggunakan nilai yang ditentukan.

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)

Parameter

context

ManagementNamedValueCollection

Objek pasangan nilai bernama khusus penyedia yang akan diteruskan ke penyedia.

timeout

TimeSpan

Lamanya waktu untuk membiarkan operasi dilakukan sebelum waktu habis. Nilai defaultnya adalah TimeSpan.MaxValue. Mengatur parameter ini akan memanggil operasi secara semisinkron.
