确定网络连接链接速度 [英] Determining the network connection link speed

问题描述

如何以编程方式确定活动网络连接的网络连接速度（如任务管理器在网络选项卡中显示）？我不是真的在带宽可用后，只是一个数字为当前连接，例如。 54Mbps，100Mbps等。

How do I programmatically determine the network connection link speed for an active network connection - like Task Manager shows you in the Networking tab? I'm not really after the bandwidth available, just a figure for the current connection, e.g. 54Mbps, 100Mbps etc.

推荐答案

最后，我发现 Win32_PerfRawData_Tcpip_NetworkInterface WMI类，因为我需要支持legacy平台，不幸的是， Win32_NetworkAdapter 不会。 Win32_PerfRawData_Tcpip_NetworkInterface 有一个 CurrentBandwidth 属性，它给我在所有必需的平台上我需要的（我意识到我说我没有需要带宽，但它是可接受的，并似乎返回适配器的标称带宽）。

In the end I found the Win32_PerfRawData_Tcpip_NetworkInterface WMI class, as I need to support legacy platforms which, unfortunately, the Win32_NetworkAdapter doesn't do. Win32_PerfRawData_Tcpip_NetworkInterface has a CurrentBandwidth property which gives me what I need on all required platforms (I realise I said I didn't need "bandwidth" but its acceptable and appears to return the "nominal bandwidth" of the adapter anyway).

感谢所有的人，指出我的方向。

Thanks to all those who posted, pointing me in the right direction.
