如何调用CODEDOM生成的动态类

[Lixin19821010]

大家好,有问题请教如下:
比如我用CODEDOM生成一个TEST.CS文件,在后来的代码中需要调用这个TEST.CS.
如何做?

生成的TEST.CS是存放在BIN.DEBUG文件下,在SOLUTION的文件夹下并没有自动添加.

十分感谢关注,如果有知道的请给予建设性指导意见.

ArrayList arraylist = new ArrayList();
arraylist.Add("unitId");
arraylist.Add("unitIdd");
Assembly assembly = NewAssembly();
object Class1 = assembly.CreateInstance("DynamicClass");
for (int i = 0; i < arraylist.Count; i++)
{
ReflectionSetProperty(Class1, arraylist[i].ToString(), "SEYU" + i);
ReflectionGetProperty(Class1, arraylist[i].ToString());
}
this.propertyGrid1.SelectedObject = Class1;

编译，加载，然后反射调用
如果要写的好一点，建议生成的类实现某个预先定义好的接口，然后用反射创建实例再用接口调用成员
