You can use this

You can install using NuGet, see SimpleHelpers.ObjectDiffPatch at NuGet.org

PM> Install-Package SimpleHelpers.ObjectDiffPatch

Use:

StyleDetail styleNew = new StyleDetail() { Id = "12", Code = "first" };
StyleDetail styleOld = new StyleDetail() { Id = "23", Code = "second" };
var diff = ObjectDiffPatch.GenerateDiff (styleOld , styleNew );

// original properties values
Console.WriteLine (diff.OldValues.ToString());

// updated properties values
Console.WriteLine (diff.NewValues.ToString());
