StdRegProv-WMI代码生成器 [英] StdRegProv - WMI Code Generator

问题描述

您好，

我正在尝试使用StdRegProv的WMI代码生成器通过注册表获取已安装应用程序的列表.使用该工具，我得到以下信息:

ManagementObject classInstance =
新的ManagementObject(``root \\ DEFAULT''，
获取方法
的参数内的参数ManagementBaseObject inParams =
classInstance.GetMethodParameters("EnumValues")和

<2147483650;
inParams ["sSubKeyName"] ="SOFTWARE \\ Microsoft \\ Windows \\ CurrentVersion \\ Uninstall \\";

ManagementBaseObject outParams =
classInstance.InvokeMethod("EnumValues"，inParams，null);

br>控制台.Wr iteLine("ReturnValue:" + outParams ["ReturnValue"]);
Console.WriteLine("sNames:" + outParams ["sNames"]);
; Types]);

但是在ManagementObject类上，在运行时出现以下错误:

指定的参数不在有效值范围内.
参数名称:path

有人可以为我指出解决该问题所需的正确方法吗?

谢谢

Hi there,

I'm experimenting with the WMI code generator using StdRegProv to get a list of installed applications via the registry. Using that tool I get the following:

 ManagementObject classInstance =
                    new ManagementObject("root\\DEFAULT",
                    "StdRegProv", null);

                // Obtain in-parameters for the method
                ManagementBaseObject inParams =
                    classInstance.GetMethodParameters("EnumValues");

                // Add the input parameters.
                inParams["hDefKey"] =  2147483650;
                inParams["sSubKeyName"] =  "SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Uninstall\\";

                // Execute the method and obtain the return values.
                ManagementBaseObject outParams =
                    classInstance.InvokeMethod("EnumValues", inParams, null);

                // List outParams
                Console.WriteLine("Out parameters:");
                Console.WriteLine("ReturnValue: " + outParams["ReturnValue"]);
                Console.WriteLine("sNames: " + outParams["sNames"]);
                Console.WriteLine("Types: " + outParams["Types"]);

But on the ManagementObject class I get the following error on runtime:

Specified argument was out of the range of valid values.
Parameter name: path

Can anyone please point me into the right direction to what I need to do to solve this problem?

Thanks

推荐答案

你好，

我想您的错误是在创建ManagementObject的过程中发生的.

I suppose that your error is happening during the creation of the ManagementObject.

对于具有3个参数的构造函数，参数路径是第二个参数路径:StdRegProv

With a constructor having 3 parameters, the parameter path is the 2nd one  that's to say  : StdRegProv

我将尝试在计算机上重复您的问题(有关WMI的每件事对我来说都很有趣)

I will try to repeat your problem on my computer ( every thing about WMI is interesting me )

您的操作系统是哪个(XP，Vista或Windows Server 2003)?

Which is your OS ( XP,Vista or Windows Server 2003 ) ?

祝你愉快
