what model binding in asp.net mvc, why needed? can give simple example , can model binding achieved checking create typed view?

modelbinding mechanism asp.net mvc uses create strongly-typed objects (or fill primitive-type parameters) input stream (usually http request).

for example, consider person model:

public class person {      public string name { get; set; }      public int age { get; set; } }

now, have action in controller that's expecting person type parameter:

public class homecontroller : controller {       public actionresult editpersondetails(person person)       {           // ...       } }

the model-binder responsible fill person parameter you. default consulting valueproviders collection , asking value of each property in (to bound) model.
