初始化 InvokeMethodOptions 類別的新執行個體,以進行叫用作業。
多載
InvokeMethodOptions() |
使用預設值,初始化 InvokeMethodOptions 作業的 InvokeMethod(String, Object[]) 類別新執行個體。 這是無參數建構函式。 |
InvokeMethodOptions(ManagementNamedValueCollection, TimeSpan) |
使用指定值,初始化叫用作業的 InvokeMethodOptions 類別新執行個體。 |
InvokeMethodOptions()
使用預設值,初始化 InvokeMethodOptions 作業的 InvokeMethod(String, Object[]) 類別新執行個體。 這是無參數建構函式。
public:
InvokeMethodOptions();
public InvokeMethodOptions ();
Public Sub New ()
範例
下列範例會叫用 Win32_Process::Create 方法來啟動 Calc.exe 的新程式。 使用類別的無參數建 InvokeMethodOptions 構函式。
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"]);
}
}
Imports System.Management

適用於
InvokeMethodOptions(ManagementNamedValueCollection, TimeSpan)
使用指定值,初始化叫用作業的 InvokeMethodOptions 類別新執行個體。
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
要經由提供者傳送的特定提供者、名稱值配對的物件。
- timeout
- TimeSpan
讓作業在逾時之前執行的時間長度。預設值為 TimeSpan.MaxValue。 設定這個參數會半同步叫用作業。
