用C#在移动宽带api Windows 7和Windows 8上苦苦挣扎，不确定要安装什么 [英] struggling with mobile broadband api windows 7 and windows 8 with C#, not sure what to install

问题描述

我有一个需要控制移动宽带API的应用程序.

我正在努力在自己的设备上正确安装api.

我一直按照本文档中的说明进行操作:

C#读取Windows Mobile宽带连接属性

我已经能够从Visual Studio到V7.0/lib中的mbnapi.tlb进行引用.我现在在obj/debug文件夹中自动有了一个interop.mbnapi.tlb.

当尝试检查SIM卡是否已插入并正在工作/已激活"时. =>我的代码在下一行崩溃

IMbnInterface[] mobileInterfaces = mbnInfMgrInterface.GetInterfaces() as IMbnInterface[];

当我在Windows 8上运行它时，mbnInfMgrInterface == null

我已经尝试按照文档要求在Windows 8上安装相同的SDK，但该SDK仅适用于Windows 7 ...

我试图通过执行在Windows 8中注册mbnapi

Regtlibv12 Mbnapi.tlb

没有运气...

请问该怎么做才能使它正常工作?

有人对此有经验吗?

编辑.在Windows 7(我的开发机)上，我收到消息设备未就绪"，我认为这很正常，因为我没有移动宽带，在Windows 8上却可以，但是移动接口管理器为null = > mbnInfMgrInterface == null.

谢谢

解决方案

不确定确切的内容，但是在与IMbnInterface和GetSignalStrength()纠缠之后(请参阅

请在此处查看答案:确定网络连接链接速度，这是您可以获得的属性列表: https://code.msdn.microsoft.com/windowsapps/network -information-sample-63aaa201

        string connectionProfileInfo = string.Empty;
        ConnectionProfile InternetConnectionProfile = NetworkInformation.GetInternetConnectionProfile();

        if (InternetConnectionProfile == null)
        {
            rootPage.NotifyUser("Not connected to Internet\n", NotifyType.StatusMessage);
        }
        else
        {
            connectionProfileInfo = GetConnectionProfile(InternetConnectionProfile);
            OutputText.Text = connectionProfileInfo;
            rootPage.NotifyUser("Success", NotifyType.StatusMessage);
        }

        // Which calls this function, that allows you to determine how strong the signal is and the associated bandwidth
        string GetConnectionProfile(ConnectionProfile connectionProfile)
        {
            // ...
                if (connectionProfile.GetSignalBars().HasValue)
                {
                    connectionProfileInfo += "====================\n";
                    connectionProfileInfo += "Signal Bars: " + connectionProfile.GetSignalBars() + "\n";
                }
            // ...
        } 

I have an application that requires to control mobile broadband API.

I am struggling on correctly installing the api on my devices.

I've been follow the instructions in this document:

http://www.google.be/url?sa=t&rct=j&q=&esrc=s&frm=1&source=web&cd=1&cad=rja&ved=0CC0QFjAA&url=http%3A%2F%2Fdownload.microsoft.com%2Fdownload%2F7%2FE%2F7%2F7E7662CF-CBEA-470B-A97E-CE7CE0D98DC2%2FMB_ManagedCode.docx&ei=kyvmUs7jE4e60QWbooHYDg&usg=AFQjCNG6yaGf4sRhdbWI99fE7tmQX8cmnA&sig2=2Fg-_DRYBIselKR19wTq2Q

and trying to combine the steps with this stackoverflow explanation

C# Read Windows Mobile Broadband connection properties

I have been able to lay a reference from visual studio to mbnapi.tlb in V7.0/lib. and I automatically now have a interop.mbnapi.tlb in my obj/debug folder.

When trying to "check the SIM is inserted and working / activated". => my code crashes on the following line

IMbnInterface[] mobileInterfaces = mbnInfMgrInterface.GetInterfaces() as IMbnInterface[];

When I run it on windows 8, mbnInfMgrInterface == null

I have already tried to install the same SDK on windows 8 as stated in the requirements of the document but the SDK is only meant for windows 7...

I have tried to register the mbnapi in windows 8 by performing

Regtlibv12 Mbnapi.tlb

no luck whatsoever...

what do I need to do to get this to work please?

anyone has some experience in this?

EDIT. on windows 7 (my development machine), I get the message "Device not ready", I think this is normal because I don't have mobile broadband on it, on windows 8 I do, but there the mobile interface manager is null => mbnInfMgrInterface == null.

thank you,

Not sure exactly what you are after, but after struggling with IMbnInterface and GetSignalStrength() (see https://msdn.microsoft.com/en-us/library/windows/desktop/dd323166(v=vs.85).aspx) and being unsuccessful, I found that you can obtain a lot of info using WMI:

        int maxBandwidth = 0;
        string query = "SELECT * FROM Win32_PerfRawData_Tcpip_NetworkInterface";
        ManagementObjectSearcher moSearch = new ManagementObjectSearcher(query);
        ManagementObjectCollection moCollection = moSearch.Get();
        foreach (ManagementObject mo in moCollection)
        {
            if (Convert.ToInt32(mo["CurrentBandwidth"]) > maxBandwidth)
            {
                // Instead of CurrentBandwidth you may want to use BytesReceivedPerSec
                maxBandwidth = Convert.ToInt32(mo["CurrentBandwidth"]);
            }
        }

Please see answer here: Determining the network connection link speed and here is the list of properties you can obtain: https://msdn.microsoft.com/en-us/library/aa394293(VS.85).aspx

UPDATE:

Please note that I can build and debug the above code (as part of a larger WPF application) from within Visual Studio 2015 on either Windows 7 or Windows 8.1, and I can deploy the same application onto Windows 7 where it runs successfully. For some reason when I deploy this application on Windows 8.1, I get an Invalid query message.

UPDATE 2:

Please note that I found you cannot get the network info in Windows 8.1 in the same way as you do in Windows 7, in that the System.Management namespace is not available on Windows 8.1. See https://code.msdn.microsoft.com/windowsapps/network-information-sample-63aaa201

        string connectionProfileInfo = string.Empty;
        ConnectionProfile InternetConnectionProfile = NetworkInformation.GetInternetConnectionProfile();

        if (InternetConnectionProfile == null)
        {
            rootPage.NotifyUser("Not connected to Internet\n", NotifyType.StatusMessage);
        }
        else
        {
            connectionProfileInfo = GetConnectionProfile(InternetConnectionProfile);
            OutputText.Text = connectionProfileInfo;
            rootPage.NotifyUser("Success", NotifyType.StatusMessage);
        }

        // Which calls this function, that allows you to determine how strong the signal is and the associated bandwidth
        string GetConnectionProfile(ConnectionProfile connectionProfile)
        {
            // ...
                if (connectionProfile.GetSignalBars().HasValue)
                {
                    connectionProfileInfo += "====================\n";
                    connectionProfileInfo += "Signal Bars: " + connectionProfile.GetSignalBars() + "\n";
                }
            // ...
        }
