逃脱Asp.Net MVC框架/枷锁,使用Razor视图引擎(4)

 
最后，看看视图模板类，一个基类和一个泛型基类，后者用于前类型Model
[csharp]
public abstract class TemplateBase 
    { 
        public string Layout { get; set; } 
        public UrlHelper Url { get; set; } 
        public Func<string> RenderBody { get; set; } 
        public string Path { get; internal set; } 
        public string Result { get { return Writer.ToString(); } } 
 
        protected TemplateBase() 
        { 
        } 
 
        public TextWriter Writer 
        { 
            get 
            { 
                if(writer==null) 
                {writer = new StringWriter(); 
                } 
                return writer; 
            } 
            set {  
                writer = value; 
            } 
        } 
 
        private TextWriter writer; 
 
        public void Clear() { 
           Writer.Flush(); 
        } 
 
        public virtual void Execute() { } 
 
        public void Write(object @object) { 
            if (@object == null) { 
                return;
