Share constants between C# and Javascript in MVC Razor

Question

I\'d like to use string constants on both sides, in C# on server and in Javascript on client. I encapsulate my constants in C# class

namespace MyModel
{
             


        

Answer 1

My version to create a namespaced javascript object from my C# constants that is immutable:

public static HtmlString GetConstants()
        {
            StringBuilder jsConstant = new StringBuilder();
                jsConstant.Append("myApp." + typeof(T).Name + " = Object.freeze({");
            foreach(var item in typeof(T).GetFields())
            {
                jsConstant.Append(string.Format("{0}:'{1}'",item.Name,item.GetValue(null).ToString()) + ",");
            }
            jsConstant.Remove(jsConstant.Length - 1, 1);
            jsConstant.Append("})");
            return new HtmlString(jsConstant.ToString());
        }

Used like this in Razor:

@(HtmlHelpers.GetConstants())
