给定具有以下数据注释的模型:
public class Example
{
[Required]
[Display(Name = "Activity response")]
public string ActivityResponse { get; set; }
}
我希望模型状态错误消息是“ Activity 响应字段是必需的”。相反,它是“ActivityResponse字段为必填字段”。
最佳答案
遇到了同样的问题,我为此采取了解决方法。
我知道这并不完美。
为每个dataannotation属性创建一个新类
public class RequiredAttribute : System.ComponentModel.DataAnnotations.RequiredAttribute
{
protected override ValidationResult IsValid(object value, ValidationContext validationContext)
{
validationContext.DisplayName = ModelMetadataProviders
.Current
.GetMetadataForProperty(null, validationContext.ObjectType, validationContext.DisplayName)
.DisplayName;
return base.IsValid(value, validationContext);
}
}
public class StringLengthAttribute : System.ComponentModel.DataAnnotations.StringLengthAttribute
{
public StringLengthAttribute(int maximumLength)
: base(maximumLength)
{ }
protected override ValidationResult IsValid(object value, ValidationContext validationContext)
{
validationContext.DisplayName = ModelMetadataProviders
.Current
.GetMetadataForProperty(null, validationContext.ObjectType, validationContext.DisplayName)
.DisplayName;
return base.IsValid(value, validationContext);
}
}
ETC....
关于validation - Web Api ModelState验证忽略了DisplayAttribute,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/14142133/
