asp.net-mvc Model binding Binding to objects
Example
Often you'd be working with viewmodel classes in asp.net-mvc and would want to bind to properties on these. This works similar to mapping to individual parameters.
Say you had a simple view model call PostViewModel like this
public class PostViewModel{
public int Id {get;set;}
public int SnappyTitle {get;set;}
}
Then you had posted values of Id and SnappyTitle from a form in the http request then they would map right onto that model if the model itself was the action parameter, e.g.
public ActionResult UpdatePost(PostViewModel viewModel){
//viewModel.Id would have our posted value
}
It's worth noting the binding is case insensitive for the parameter and property names. It will also cast values where possible. I'm leaving more edge cases for specific examples
