对于一些大型的项目,通常由很多个DLL文件组成,引用了这些DLL,就能访问DLL里面的类和类里面的方法。假如你写了一个记录日志的DLL,任何项目只要引用此DLL就能实现记录日志的功能,这个DLL文件的程序就是一个程序集。如果你记录日志的程序集是这么定义的:
namespace LogerHelper {    internal class aa    {         public void bb()         {             return "";         }    }    public class Write    {        public void WriteIn(string content)        {            class x = new aa();                x.bb();        }    }}
当另一个项目引用了此DLL,它可以这么访问 :
LogerHelper.Write x = new LogerHelper.Write();x.WriteIn("");
但不可以这么访问:
LogerHelper.aa x = new LogerHelper.aa();x.bb();
这就叫,只能在程序集中访问
