推荐答案

出了什么问题?我们无法为您提供代码，我们也不知道分支或区域代码格式，因此我们对其其余部分一无所知.但是随机很容易:

What is the problem? We can''t give you code, we don''t know the branch or area code formats, so we have no idea about the rest of it. But Random is easy:

private Random rand = new Random(); // Class level random number generator
...
int randomNumber = rand.Next(1000000);           // Generate a random number between 0 and 999999
string randomCode = randomNumber.ToString("D6"); // Convert it to six digits, 0 padded.

然后结合您的分支和区号，看看它是否已经在数据库中了！
您可能想添加一个校验位或类似的数字，以使人为错误更难以插入...

Then combine with your branch and area codes, and see if it is in the db already!
You might want to add a check digit or similar to make it harder for human error to slip in...
