如何在C＃上生成随机银行帐号 [英] How do I generate random bank account number on C#

问题描述

我想生成银行帐号，该号码必须以32开头，例如32098723,32162545,32752934等。它必须是8位数。任何人都可以帮助我，谢谢你。



我尝试过：



public long GetNewAccountNumber（long accountNumber）

{

随机随机= new Random（）;

long newAccountNumber = random.Next（ 32000000,33000000）;





返回newAccountNumber;









}

What I have tried:

public long GetNewAccountNumber(long accountNumber)

Random random = new Random();
long newAccountNumber = random.Next(32000000, 33000000);


return newAccountNumber;




}

推荐答案

这是：

Here it is:

String startWith = "32";
Random generator = new Random();
String r = generator.Next(0, 999999).ToString("D6");
String aAccounNumber = startWith + r;

解决方案1为您提供伪随机数，并且应该真的警告过您的含义（例如，您最终可能会一式两份）。有关详细信息，请参阅文档随机类（系统）| Microsoft Docs [ ^ ]



您可能最好使用 RNGCrypto服务提供商类 [ ^ ]。有一些如何在该链接上执行该操作的示例。



一旦你有随机数 r 你就可以使用

Solution 1 is providing you with pseudo-random numbers and should really have warned you about the implications of that (e.g. you could end up with duplicates). See the documentation for further information Random Class (System) | Microsoft Docs[^]

You would probably be better off using the RNGCrypto​Service​Provider Class[^]. There are examples of how to do that on that link.

Once you have your random number r you can generate your bank account number with

string accNumber = String.Format("32{0}", r.ToString("D6"));

现在注意来自@ppolymorphe和@ George-Swan的评论 - 银行账户不仅仅是随机数，他们遵循非常具体的规则。一旦你产生了你的号码，你应该检查它是否有效。

这是一篇关于主题的Codeproject文章IBAN Validator [ ^ ]



有许多商业产品和API可以进行验证。

Now note the comments from @ppolymorphe and @George-Swan - Bank Accounts are not just random numbers, they follow very specific rules. Once you have generated your number you should check that it is valid.

Here is another example of a validation tool Sortcode and Bank Account Validation - C# Developers Guide[^]

And here is a Codeproject article on the subject IBAN Validator[^]

There are many commerical products and APIs available to do the validation.
