读取“实体框架的最大长度”字段并分配给Razor视图中的文本框

Question

I want to map each field the user enters data into correlates with a database field that can easily set by reading database table definition and set it manually in razor view by setting maximum or in my view model but I need to make it dynamic if Database administrator change the maximum character limit through SQL server it will automatically update the maximum limit of character in text field. I am trying to read it from Entity framework and set it in razor view. Is this possible to make it dynamic in any way.

And how can I read max length field from razor view.

Answer 1

After further search I figure out how to read maximum length of field from Entity Framework Schema

public void read()
        {
            using (var db = new PortalContext())
            {
                var objectContext = ((IObjectContextAdapter)db).ObjectContext;
                var container = objectContext.MetadataWorkspace.GetEntityContainer(objectContext.DefaultContainerName, DataSpace.CSpace);
                int maxLength = (int)container.EntitySets["Customers"].ElementType.Properties["LastName"].MaxLength;
            }
        }
