具体功能就是通过反射为实体类赋值

public class httpParse<T> where T : new()
    {
        /// <summary>
        /// 为Model赋值
        /// </summary>
        /// <param name="t">需要转换的实体</param>
        /// <param name="form">外部传入的form表单</param>
        /// <returns>转换成功的属性数</returns>
        public static int GetPost(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(Exception ex)
                    {
                        throw ex;
                    }
                }
            }
            return va;
        }

这个在一些页面像前台传值的时候 可以很大程度减少人工手动的赋值
