我在模型中有2个属性Contractor1和Contractor2,如何对它们两个都使用单个远程验证

[Display(Name ="Contractor 1:")]
[Remote("ValidateContractor", "Contracts")]
public string Cntrctr1 {get; set;}

[Display(Name = "Contractor 2:")]
[Remote("ValidateContractor", "Contracts")]`enter code here`
public string Cntrctr2 {get; set;}

Controller 中的远程验证功能
public JsonResult ValidateContractor1(string Cntrctr)
{
    var valid = Validations.ValidateContractor(Cntrctr);
    if (!valid)
    {return Json("Enter correct contractor", JsonRequestBehavior.AllowGet);}
    else{return Json(true, JsonRequestBehavior.AllowGet);}
}
public static bool ValidateContractor(string CntrctrNM)
{
    bool valid;
    using (var entities = new CAATS_Entities())
    {
        var result = (from t in entities.PS_VENDOR_V
                      where (t.VNDR_1_NM).Equals(CntrctrNM)
                      select t).FirstOrDefault();
        if (result != null)
        {
            valid = true;
        }
        else
        {
            valid = false;
        }
    }
    return valid;

}

这是行不通的。你能帮我吗?

最佳答案

调用远程验证时,querystring键是字段的名称,例如在您的情况下/Contracts/ValidateContractor1?Cntrctr1=foo。您需要一个更动态的解决方案。

一种方法是在ValidateContractor1中不包含任何参数,而只是获取第一个查询字符串值。这未经测试,但应该为您工作:

public JsonResult ValidateContractor1()
{
   // gets the name of the property being validated, e.g. "Cntrctr1"
   string fieldName = Request.QueryString.Keys[0];

   // gets the value to validate
   string Cntrctr = Request.QueryString[fieldName];

   // carry on as before
   var valid = Validations.ValidateContractor(Cntrctr);
   if (!valid)
   {return Json("Enter correct contractor", JsonRequestBehavior.AllowGet);}
   else{return Json(true, JsonRequestBehavior.AllowGet);}
}

关于c# - 对模型中的2个不同属性进行相同的远程验证,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/27807745/
