MVC Learning Series -- ActionResult extension, mvcactionresult

MVC Learning Series -- ActionResult extension, mvcactionresult

First, MVC is highly scalable.

I started with the extension of ActionResult, because we know that Microsoft ActionResult and its subclass cannot satisfy all returned values.

For example, I need to return XML.

Therefore, now I extend XMLResult to inherit ActionResult.

Step 1: Create an XmlResult

 1 public class XmlResult:ActionResult 2     { 3         private object _data; 4  5         public XmlResult(object data) 6         { 7             this._data = data; 8         } 9         public override void ExecuteResult(ControllerContext context)10         {11             var serializer = new XmlSerializer(_data.GetType());12             var reponse = context.HttpContext.Response;13             reponse.ContentType = "text/xml";14             serializer.Serialize(reponse.Output, _data);15         }16     }

Step 2: Create a StudentViewModel class for demonstration

1 public class StudentViewModel2     {3         public string ID { get; set; }4         public string Name { get; set; }5         public string Gender { get; set; }6     }

Step 3: Add GetXmlResult in HomeController

1  public XmlResult GetXmlResult()2         {3             StudentViewModel viewModel = new StudentViewModel();4             viewModel.ID = "1";5             viewModel.Name ="Zhangsan";6             viewModel.Gender = "Man";7 8             return new XmlResult(viewModel);9         }

Step 4: Test
Enter Home/GetXmlResult in IE
