初始化該操作的新InvokeMethodOptions實例InvokeMethod(String, Object[])，使用預設值。這就是無參數建構子。

public:
 InvokeMethodOptions();

public InvokeMethodOptions();

Public Sub New ()

範例

以下範例引用 Win32_Process：：Create 方法來啟動新的 Calc.exe流程。使用類別的 InvokeMethodOptions 無參數建構子。

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)

來源:: ManagementOptions.cs

來源:: ManagementOptions.cs

來源:: ManagementOptions.cs

來源:: ManagementOptions.cs

使用指定的值初始化該類別的新實例 InvokeMethodOptions 以執行呼叫操作。

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)

參數

context: ManagementNamedValueCollection

提供者專用的命名值對物件會傳遞給提供者。

timeout: TimeSpan

操作執行完畢的時間長度。預設值為 TimeSpan.MaxValue。設定此參數會以半同步方式啟動操作。

範例

以下範例引用 Win32_Process：：Create 方法來啟動新的 Calc.exe流程。 InvokeMethodOptions該類別用來呼叫該方法。

using System;
using System.Management;

// This sample demonstrates invoking

        ManagementClass processClass =

        // 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
