C# 如何从actionfilter中的属性获取值
这个标题看起来有点奇怪,抱歉 我是Asp.NETMVC3的新手。我想为我的一个属性创建一个属性,该属性的名称是national identity numberC# 如何从actionfilter中的属性获取值,c#,asp.net-mvc-3,attributes,actionfilterattribute,C#,Asp.net Mvc 3,Attributes,Actionfilterattribute,这个标题看起来有点奇怪,抱歉 我是Asp.NETMVC3的新手。我想为我的一个属性创建一个属性,该属性的名称是national identity number public class IdentityNumberControl : ActionFilterAttribute { public string WrongIdentityNumber { get; set; } public override void OnActionExecuting(ActionExec
public class IdentityNumberControl : ActionFilterAttribute

public string WrongIdentityNumber { get; set; }
public override void OnActionExecuting(ActionExecutingContext filterContext)

if(??? )
{
filterContext.HttpContext.Response.Write(WrongIdentityNumber);
return;

base.OnActionExecuting(filterContext);

我的会员班在这里
public class Member
{
public int ID { get; set; }
[Required(ErrorMessage = "You have to enter your name")]
[StringLength(50, ErrorMessage ="Your name length can not be less than{2} more than {1} ", MinimumLength = 3)]
[Display("Name :")]
public string Name { get; set; }
[Required(ErrorMessage = "You have to enter your surname")]
[StringLength(40, ErrorMessage = "Your surname length can not be less than{2} more than {1} ", MinimumLength = 2)]
[Display("Surname :")]
public string SurName { get; set; }
[Required(ErrorMessage = "You have to enter your password")]
[StringLength(20, ErrorMessage = "Your name lengt can not be less than{2} more than {1} ", MinimumLength = 6)]
[DataType(DataType.Password)]
[Display("Password :")]
public string Password { get; set; }
public string PasswordSalt { get; set; }
[IdentityNumberControl(WrongIdentityNumber = "It is not a valid identity number")]
public double IdentityNumber { get; set; }
}
所以我想检查identitynumber是否为真(我有一个计算方法来确认)
我知道我必须在IdentityNumberControl类中编写代码。但我不知道如何在OnActionExecuting方法中获得identitynumber的值
我希望我能解释我的问题这里是我的解决方案
public class IdentityNumberAttribute : ValidationAttribute
{
private string WrongIdentityNumber;
public IdentityNumberAttribute(string message)
{
WrongIdentityNumber = message;
}
protected override ValidationResult IsValid(object value, ValidationContext validationContext)
{
string identityNumber = value.ToString();
if (identityNumber.Length != 11)
return new ValidationResult(WrongIdentityNumber);
int sum = 0;
for (int i = 0; i < identityNumber.Length - 1; i++)
{
sum += Convert.ToInt32(identityNumber[i].ToString());
}
return sum.ToString()[1] == identityNumber[10]
? ValidationResult.Success
: new ValidationResult(WrongIdentityNumber);
}
}
好吧,我找到了解决办法。我已经实现了ValidationAttribute而不是ActionFilterAttribute:)如果您找到了解决方案,请将其作为答案发布并接受。这样,未来的用户就会了解如何解决这个问题。
[IdentityNumber("It is not a valid identity number")]
[Required(ErrorMessage = "You have to enter your identity number")]
[DisplayName("National Identity Number:")]
public string IdentityNumber { get; set; }
