InvokeMethodOptions 构造函数

定义

命名空间:

System.Management

程序集:

System.Management.dll

包:

System.Management v8.0.0

为调用操作初始化 InvokeMethodOptions 类的新实例。

重载

InvokeMethodOptions()	使用默认值，为 InvokeMethodOptions 操作初始化 InvokeMethod(String, Object[]) 类的新实例。 这是无参数构造函数。
InvokeMethodOptions(ManagementNamedValueCollection, TimeSpan)	使用指定的值，为调用操作初始化 InvokeMethodOptions 类的新实例。

InvokeMethodOptions()

Source:

ManagementOptions.cs

使用默认值，为 InvokeMethodOptions 操作初始化 InvokeMethod(String, Object[]) 类的新实例。 这是无参数构造函数。

public:
 InvokeMethodOptions();

public InvokeMethodOptions ();

Public Sub New ()

示例

以下示例调用 Win32_Process：：Create 方法以启动 Calc.exe 的新过程。 使用 类的 InvokeMethodOptions 无参数构造函数。

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)

Source:

ManagementOptions.cs

使用指定的值，为调用操作初始化 InvokeMethodOptions 类的新实例。

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)

参数

context

ManagementNamedValueCollection

要传递给提供程序的、提供程序特定的名称-值对对象。

timeout

TimeSpan

让操作在超时之前执行的时间长度。默认值为 TimeSpan.MaxValue。 设置此参数将半同步地调用该操作。

示例

以下示例调用 Win32_Process：：Create 方法以启动 Calc.exe 的新过程。 类 InvokeMethodOptions 用于调用 方法。

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

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

        InvokeMethodOptions methodOptions = new
            InvokeMethodOptions(null,
