C#的Assembly反射机制

通过C#的Assembly反射机制可以动态的调用一个类以及该类中的方法和属性：

string spath = this.TargetPath.Trim().Trim('\\')+"\\DB.dll"; 

Assembly a = Assembly.LoadFrom(spath);  //获得dll路径
Type calltype = a.GetType("SystemAdmin.DbBase");
object Callobject = Activator.CreateInstance(calltype);  //Activator.CreateInstance创建实例

string method =  "sGetSubSystemID";
object returnvalue = 0;
Type t = Callobject.GetType();
MethodInfo [] m = t.GetMethods() ;
object result;  

for(int i = 0; i < m.Length; i++)
{
    if(m[i].Name == method)
    {
        result = m[i].Invoke(Callobject,null);
    }
}
