我們知道ASP.NET MVC有個(gè)強(qiáng)大的地方就是Form表單提交到action的時(shí)候，可以直接將Form的參數(shù)直接裝配到action的參數(shù)實(shí)體對(duì)象中
action方法 Register(UserModel userModel)
{
.............................
}
因?yàn)槊看味家カ@得數(shù)據(jù)，優(yōu)秀的程序員應(yīng)該要學(xué)會(huì)代碼封裝，代碼復(fù)用，重復(fù)的工作不要做
好了廢話不多....

protected PropertyInfo[] GetPropertyInfoArray(Type type)
{

try

object obj = Activator.CreateInstance(type);
props = type.GetProperties(BindingFlags.Public | BindingFlags.Instance);
}
catch (Exception ex)
{
}
return props;
}

{
PropertyInfo[] propertyInfoList = GetPropertyInfoArray(typeof(T));
object obj = Activator.CreateInstance(typeof(T), null);//創(chuàng)建指定類型實(shí)例
foreach (string key in valueCollection.Keys)//所有上下文的值
{
foreach (var PropertyInfo in propertyInfoList)//所有實(shí)體屬性
{
if (key.ToLower() == PropertyInfo.Name.ToLower())
{
PropertyInfo.SetValue(obj, valueCollection[key], null);//給對(duì)象賦值
}
}
}
return (T)obj;
}
