c# 创建类(.cs)
不用Stream创建
有没有其他的,比如创建xml有xmlDocument 这样可以有相对的格式,创建.cs文件有没有相关的对象?

------解决方案--------------------
System.CodeDom


内容可能太短。。。
------解决方案--------------------
？？
动态创建类
？？？
和你cs文件有何关系，cs是输出，类是运行期？？

如果要动态创建，运行期类，参考codedom
如果要输出cs文件，参考Microsoft.CSharp.CSharpCodeProvider类
------解决方案--------------------
LZ是不是要生成一个cs文件阿？但又要像自己在VS里写的那样自动缩进？
------解决方案--------------------
楼主是想根据类图之类的东西生成.cs文件吧
CodeDom
------解决方案--------------------
不知道lz的意思是否是这样
