asp.net实现利用反射，泛型，静态方法快速获取表单值到Model的方法

News news = new News();
news.Id = int.Parse(Request.Form["Id"]);
news.Category = int.Parse(Request.Form["Category"]);
news.Title = Request.Form["Title"];
news.CreateTime = DateTime.Parse(Request.Form["CreateTime"]);

public static class HenqPost<T> where T: new()
{
  /// <summary>
  /// 为Model赋值
  /// </summary>
  /// <typeparam name="T">Model</typeparam>
  /// <param name="t">model</param>
  /// <param name="form">Request</param>
  /// <returns></returns>
  public static int GetPost<T>(ref T t, NameValueCollection form)
  {
   int va=0;
   Type type = t.GetType();//获取类型
   PropertyInfo[] pi=type.GetProperties();//获取属性集合
   foreach( PropertyInfo p in pi )
   {
    if (form[p.Name] != null)
    {
     try
     {
      p.SetValue(t, Convert.ChangeType(form[p.Name], p.PropertyType), null);//为属性赋值，并转换键值的类型为该属性的类型
      va++;//记录赋值成功的属性数
     }
     catch
     {
     }
    }
   }
   return va;
  }
}

News news = new News();
HenqPost<News>.GetPost(ref news, Request.Form);
//烦人的为实体类赋值就Over了。
