Best way to get a unique identifier in C#
提问by Chris Watts
I've asked a similar question before, but I'm now reducing some of the restrictions about what I need.
我之前问过一个类似的问题，但我现在正在减少对我需要的一些限制。
I need to find a unique identifier on a computer, efficiently, with C#. It should always stay the same on any particular computer, and can be a composite of many factors - provided it's simple to retrieve.
我需要使用 C# 高效地在计算机上找到唯一标识符。它应该在任何特定计算机上始终保持不变，并且可以是许多因素的组合 - 只要它易于检索。
I've thought about using the MAC address with WMI Network queries, but this is too slow as usually there are 10+ adapters. Might be better with a WHERE IPEnabled=true clause, but I think there's probably something better than this.
我考虑过在 WMI 网络查询中使用 MAC 地址，但这太慢了，因为通常有 10 个以上的适配器。使用 WHERE IPEnabled=true 子句可能会更好，但我认为可能有比这更好的方法。
Ideas?
想法？
(P.S. It doesn't have to be TOTALLY unique. As long as the chance of collision is small, it's perfect.)
（PS 不一定要完全独一无二。只要碰撞的机会很小，就完美了。）

First Get the Processor ID like following: (Add Reference to System.Management)
首先获取处理器 ID，如下所示：（添加对 的引用System.Management）
ManagementObjectCollection mbsList = null;
ManagementObjectSearcher mbs = new ManagementObjectSearcher("Select * From Win32_processor");
mbsList = mbs.Get();
string id = "";
foreach (ManagementObject mo in mbsList)
{
id = mo["ProcessorID"].ToString();
}
//Then you can get the motherboard serial number:
//然后就可以得到主板序列号了：
ManagementObjectSearcher mos = new ManagementObjectSearcher("SELECT * FROM Win32_BaseBoard");
ManagementObjectCollection moc = mos.Get();
string motherBoard = "";
foreach (ManagementObject mo in moc)
{
motherBoard = (string)mo["SerialNumber"];
}
You can concat the above two and get a unique ID
可以concat上面两个，得到一个唯一的ID
string myUniqueID = id + motherBoard;
Console.WriteLine(myUniqueID);
