1. 用Type
在 website 下
C#代碼
//定義參數類型數組
Type[] tps = new Type[2];
tps[0] = typeof(int);
tps[1] = typeof(string);
//定義參數數組
object[] obj = new object[2];
obj[0] = (object)100;
obj[1] = (object)"Param Example";
string UserDaoPath = System.Configuration.ConfigurationSettings.AppSettings["UserDao"];
UserDao userDao = (UserDao)Type.GetType(UserDaoPath).
GetConstructor(tps).Invoke(obj );
2. 用Assembly
在 website 下 這個是導入一個 程序集 然后在程序集里再 實例化類, 我這里其實就是實例化一個類。
C#代碼
string UserServicePath = System.Configuration.ConfigurationSettings
.AppSettings["UserService"];
UserService userService = (IUserService)Assembly.Load(UserServicePath).
CreateInstance("UserService");
C#代碼
<appSettings >
<add key="UserService" value="App_Code.Service.UserService"></add>
</appSettings>
