You don't state any specific requirements but you can use a GUID.
您没有说明任何特定要求，但可以使用 GUID。
Guid mySerialNumber = Guid.NewGuid();

I have used this CodeProject Articlebefore when I've needed to do the same thing for projects I have worked on recently. I found it very detailed and while I didn't use everything in the sample I did get a lot out of it. (I have no affiliation with CodeProject or the author)
当我需要为我最近从事的项目做同样的事情时，我以前使用过这篇CodeProject 文章。我发现它非常详细，虽然我没有使用示例中的所有内容，但我确实从中受益匪浅。（我与 CodeProject 或作者没有任何关系）
Additionally there is a library which gives you all this functionality complete with license file replacement and heaps of other features, but its not free, and unfortunately I couldn't remember the link. I'm sure a bit of Googgling and you'll find it.
此外，还有一个库可以为您提供所有这些功能，包括许可证文件替换和大量其他功能，但它不是免费的，不幸的是我不记得链接了。我敢肯定，你会用一些谷歌搜索找到它。

Try a number you can test using Luhn's algorithm. That way, you can make it long an inscrutable, yet still easily confirmed. The article contains a link to a C# implementation.
尝试使用Luhn 算法可以测试的数字。那样的话，你可以让它长得高深莫测，但仍然很容易确认。该文章包含指向 C# 实现的链接。

public static string GetSerialKeyAlphaNumaric(SNKeyLength keyLength)
{
string newSerialNumber = "";
string SerialNumber=Guid.NewGuid().ToString("N").Substring(0, (int)keyLength).ToUpper();
for(int iCount=0; iCount < (int) keyLength ;iCount +=4)
newSerialNumber = newSerialNumber + SerialNumber.Substring(iCount, 4) + "-";
newSerialNumber = newSerialNumber.Substring(0, newSerialNumber.Length - 1);
return newSerialNumber;
}
