.Net Core=我想为UserValidator添加个性规则

发布于 2025-01-10 12:01:00 字数 410 浏览 0 评论 0原文

例如; 我在表中有密码列。任何人进入系统时都必须写入密码。我想要包含至少一个字符的密码，例如（/，-，？，+，！）。我做了这样一段代码；

public UserValidator()
{
    RuleFor(p => p.Password).MinimumLength(10);
    RuleFor(p => p.Password).Must(MustBeCharacter);
}
private bool MustBeCharacter(string arg)
{
    return arg.Contains("."+","+"?"+"!"+"*"+"-"+"+");
}

我有一个问题。系统需要所有这些（“.”+“，”+“？”+“！”+“*”+“-”+“+”）。但我至少还想要一份。我该怎么做这个规则。太感谢了

原文

For Example;
I have password column in the table. AnyBody while enter system must write password. I want contain password minumum one character such as(/,-,?,+,!). I did such one code;

public UserValidator()
{
    RuleFor(p => p.Password).MinimumLength(10);
    RuleFor(p => p.Password).Must(MustBeCharacter);
}
private bool MustBeCharacter(string arg)
{
    return arg.Contains("."+","+"?"+"!"+"*"+"-"+"+");
}

I take a problem. system want all of them ("."+","+"?"+"!"+"*"+"-"+"+"). but I want minimum one more. How can I do this rule.
Thank you so much

在当前的方法中，您将所有特殊字符连接成一个字符串并应用 Contains() 就可以了。这就是原因，系统期望所有特殊字符都应该是您的 arg 字符串的一部分。

您应该在数组或列表中定义所有特殊字符，然后使用 .Any() 检查字符串 arg 中至少应出现一辆特殊汽车，

private bool MustBeCharacter(字符串参数)
{ 
    varspecialChars = ".,?!*-+".ToCharArray();
    返回specialChars.Any(x => arg.Contains(x));
}

在线尝试：.Net Fiddle

In your current approach, you are concatenating all special characters into a single string and applying Contains() on it. That is the reason, the system expects all special chars should be part of your arg string.
You should define all special characters inside an array or a list, then use .Any() to check at least one special car should present in the string arg,
```
private bool MustBeCharacter(string arg)
{ 
    var specialChars = ".,?!*-+".ToCharArray();
    return specialChars.Any(x => arg.Contains(x));
}
```

系统需要所有这些字符，因为您正在查找整个字符串而不是一个字符。

你首先需要数组

private string[] arr = [".",",","?","!","*","-","+"];
private bool MustBeCharacter(string arg)
{  
        return arr.Any(s => args.Contains(s));
    
}

System want all of them because you are looking for entire string and not one character.

you need array first

private string[] arr = [".",",","?","!","*","-","+"];
private bool MustBeCharacter(string arg)
{  
        return arr.Any(s => args.Contains(s));
    
}
