2. Value of the field

I have created

//return object.name
var expressionText = ExpressionHelper.GetExpressionText(expression);


}

Answer 1

1. Name of the field

   string fullHtmlFieldName = htmlHelper
       .ViewContext
       .ViewData
       .TemplateInfo
       .GetFullHtmlFieldName(
           ExpressionHelper.GetExpressionText(expression)
       );
   

2. Value of the field

   var metaData = ModelMetadata.FromLambdaExpression(
       expression, htmlHelper.ViewData
   );
   object value = metaData.Model; // will be of type TProperty
