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
- Source:
- ManagementOptions.cs
- 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。

// 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"]);
}
