. NET WebForm simulates MVC for model binding, making yourself less overworked

The brothers who used MVC know that MVC has the data function of model binding form submission, then I also want to steal a lazy also write a webform version of the model binding. This defines a generic method, and then assigns the value of the corresponding property name on the form to the property of the reflection-created class by reflection.

Places to be noticed:

1. The attribute name of the model class that is defined corresponds to the name of the form name

2, the definition of the generic method is through the var form = context.   Request.Form; Data from the form post

 Public classdatamodel{/// <summary>    ///binding the values of the model models from the data submitted by the form/// </summary>    /// <typeparam name= "T" ></typeparam>    /// <param name= "entity" ></param>    /// <returns></returns>     Public StaticT modelbing<t>(T entity) {Objectobj = Activator.CreateInstance (typeof(T)); Type type=entity.        GetType (); Propertyinfo[] Proinfos=type.        GetProperties (); Dictionary<string, propertyinfo> dic =Newsystem.collections.generic.dictionary<string, propertyinfo>();  for(inti =0; i < proinfos.length; i++) {dic. ADD (Proinfos[i].        Name, Proinfos[i]); } HttpContext context=HttpContext.Current; varform =context.        Request.Form; string[] keys =form.        AllKeys; foreach(stringKeyinchkeys) {            if(DIC. ContainsKey (key)) {PropertyInfo PInfo=Dic[key]; varProtype =Pinfo.propertytype; ObjectValue =NULL;//Store conversion value after the corresponding type                if(string. IsNullOrEmpty (Form[key]))//when the value of post comes down                {                    if(Protype = =typeof(string))//determines whether the property is a string type to an empty string because my database does not allow null for this field{//Here I do not judge the value type's data, because the value type will have the default valuePinfo.setvalue (obj,"",NULL); }                                                           Continue; }                Try                {                    if(Protype.isenum)//If the property is an enumeration type, the conversion enumeration type{Value=Enum.toobject (Protype, Form[key]); }                    Else if(Protype.isgenerictype && ProType.Name.StartsWith ("Nullable"))//generic type{Type Newprotype=Nullable.getunderlyingtype (Protype); Value=Convert.changetype (Form[key], newprotype); }                    Else{Value=Convert.changetype (Form[key], protype); } pinfo.setvalue (obj, value,NULL); }                Catch(Exception ex) {ThrowEx//Write error log                }            }        }        return(T) obj; }}

The front desk can be validated through the Easyui framework of the form and then submitted to the backstage, here will no longer say, we understand how to use this method is good, there is not perfect place to hope you point out!
