ValidationContext.MemberName is set incorrectly in the DataAnnotationsModelValidator · Issue #120 · aspnet/AspNetWebStack (original) (raw)

Problem Description

My customer creating custom validation class which deliveerd from System.ComponentModel.DataAnnotations.ValidationAttribute.
Using this in .NET4.7.1 ASP.NET Web API 2.0, ValidationContext.MemberName is set "DisplayName".
This is problem for custom class because they can not know MemberName without this property.

• Expected behavior
  ValidationContext.MemberName is "TestValue3"
• Actual behavior
  ValidationContext.MemberName is "Display name From 'DisplayAttribute'"

TestValue3 is set "DisplayAttribute".

    public class TestModel
    {
        [Validations.CustomValidation]
        public string TestValue1 { get; set; }
        [Validations.CustomValidation(ErrorMessage = "ErrorMessage: {0} ErrorMessage")]
        public string TestValue2 { get; set; }
        [Validations.CustomValidation(ErrorMessage = "ErrorMessage: {0} ErrorMessage")]
        [Display(Name = "Display name From 'DisplayAttribute'")]
        public string TestValue3 { get; set; }
        public string Message { get; set; }
    }
