How to check a change in a Model Object fields without checking individual fields in MVC?

Question

I have a big model

public class SomeModel
{
        public int Id { get; set; }
        .....A lot(24) of Fields here.....
}

Now on Post ActionResult Edit(somemodel SomeModel) I want to check if anything has been changed by user with respect to original model values in database. Using If Else makes for a lot of messy code. Is there anyway to check if something was altered by the user and if possible what field was altered by user?

Answer 1

I was thinking about using a method like this one

    public class SomeModel
    {
    //... 
     public override bool Equals(object obj)
        {
      var type = this.GetType();
      bool SameObj = true;
     //for each public property from 'SomeModel'
     //[EDITED]type.GetProperties().Each(prop=>{ //  Sorry i'm using custom extension methode here
     //you should probably use this instead
     type.GetProperties().ToList().ForEach(prop=>{
                      //dynamically checks that they're equals 
                      if(!prop.GetValue(this,null).Equals(prop.GetValue(obj,null))){
                          SameObj=false;
                      }
                    }
                return SameObj;
    }
   }
