EF：IsValid（）中的自定义数据验证

Question

I have a custom IsValid method in my model class. Method looks like this:

public override bool IsValid(object value) {

 // How I can get field name here for some data manipulation. // some code for validation. 

}

How I can get field name which is calling this custom IsValid method from controller??? I would really appreciate if you help me in this regard. Thanks in advance.

I am taking a guess that this is what you mean. Let's say that you know that the object you are validating is of type MyValidatableClass, having a property that should have the value "correct", you can do something like this:

public override bool IsValid(object value)
{
  var objectToValidate = value as MyValidatableClass;

  // some code for validation.
  if (objectToValidate.SomeProperty != "correct")
    return false;
}
