如何将一个字符串转换成一个类的名称

[fenghua2003]

我想动态创建一个类，类的名称就是从 texBox1.text 获取, 请问如何能实现？
谢谢！

good question

用反射.
一个小例子.

class Program
    {
        public static void Main(String[] args)
        {
            string FruitName = Console.ReadLine();
            IFruit MyFruit;
            FruitFactory MyFruitFactory = new FruitFactory();
            MyFruit = MyFruitFactory.MakeFruit("tmConsoleApp." +FruitName); //必须使用名称空间+类名称

            Console.ReadLine();
        }
    }

    public interface IFruit
    { } 
    
    public class Orange:IFruit 
    { 
        public Orange()
        { 
            Console.WriteLine("An orange is got!");
        } 
    }  

    public class Apple:IFruit
    { 
        public Apple()
        { 
            Console.WriteLine("An apple is got!"); 
        } 
    }

    public class FruitFactory
    {
        public IFruit MakeFruit(string Name)
        {
            IFruit MyFruit = null;
            try
            {
                System.Type type = System.Type.GetType(Name, true);//必须使用名称空间+类名称
                MyFruit = (IFruit)Activator.CreateInstance(type);
                return MyFruit;
            }
            catch (TypeLoadException e)
            {
                Console.WriteLine("dont know this kind of fruit,exception caught - {0}", e.Message);
                return MyFruit;
            }
        }
    }

同意三楼的做法,用反射,很容易的

[lake_cx]

只有动态创建对象，动态创建类？？？运行时写类代码？

参考
使用反射生成一个窗体的例子：
Assembly assm = Assembly.LoadFrom("e:\\WindowsApplication.dll");
Type TypeToLoad= assm.GetType("WindowsApplication.Form1");

object obj;
obj = Activator.CreateInstance(TypeToLoad);
Form formToShow = null;
formToShow = (Form)obj;
formToShow.Show();
