Use C# to obtain current device hardware information

Requirement description

Now there is a requirement:

I have two servers, A and B, where A is a video processing server and B is a data storage server. At this time, there is a video that needs to be processed in a series of processes on server A before uploading it to server B for storage.

In order to reduce the workload of manual processing, server A needs to actively send data to B, and then server B receives the data and stores it. However, in this process, I do not want server B to receive data uploaded by other ends other than server A, so when B receives data, it needs to verify the source of the data.

Here, when uploading data, server A carries the hardware information of its own server. By verifying the hardware information, it can determine whether the data source is server A.

Determine which platform the current program runs on

The IsOSPlatform method is used to indicate whether the current application is running on the specified platform:

public static bool IsOSPlatform ( osPlatform);

The parameter osPlatform represents an operating system platform:

value	Description
FreeBSD	Get an object representing the FreeBSD operating system
Linux	Get an object representing the Linux operating system
OSX	Get an object representing the OSX operating system
Windows	Get an object representing the Windows operating system

ManagementObjectSearcher class obtains hardware information

ManagementObjectSearcher is a constructor. Before using it, you need to introduce the namespace using System Management. This constructor receives a string as a parameter. This string is generally written as "select * from" + key. Here there are many values of key:

ManagementObjectSearcher searcher = new ManagementObjectSearcher("select * from " + Key);

Sample code

Get the CPU serial number

private string GetServerCode()
        {
            string code = "";
            if (())
            {
                ManagementObjectSearcher searcher = new ManagementObjectSearcher("Select * From Win32_Processor");

                foreach (ManagementObject mo in ())
                {
                    code = mo["ProcessorId"].ToString().Trim();
                    break;
                }
            }
            else
            {
                code = ExecuteCommand("dmidecode -t Processor | grep ID | sort -u | awk -F':' '{print $2}'");
            }

            ("serverCode:" + code);

            return (code ?? "").Replace(" ", "").Trim();
        }

In the above example code for getting the CPU sequence number, a ManagementObjectSearcher object is first created, and then the ManagementObjectCollection collection is obtained through the Get() method, and then the ManagementObjectCollection is used to traverse the collection using the foreach method to get the ManagementObject data, and the desired attribute is obtained through managementObject[name] or (name).

However, before this, I didn't know what to fill in the value of this name. At this time, I just need to print it through console.
