DebuggerDisplay和DebuggerTypeProxy是两个属性，用来在VS调试的状态下，显示一些额外的信息，方便用户进行调试。

 

DebuggerDisplay 不单能够显示变量的值，还能调用变量的方法来计算结果显示：

class Program    {        static void Main(string[] args)        {            Company c = new Company();            Console.ReadLine();        }    }    [DebuggerDisplay("company name:{name}, employee count:{employeeNames.Count}")]    class Company    {        public string name = "Company1";        List
     
       employeeNames = new List
      
       () { "Employee1", "Employee2", "Employee3" };    }
      
     

 

DebuggerTypeProxy 可以附加一些属性在VS调试窗口中，提供了更加灵活的方式。如果DebugView中的属性和类型本身的属性名字相同，那么类型的属性将会被覆盖，在VS调试器中看不见了。

 

class Program    {        static void Main(string[] args)        {            Company2 c2 = new Company2();            Debugger.Break();            Console.ReadLine();        }    }    [DebuggerTypeProxy(typeof(Company2DebugView))]    class Company2    {        internal class Company2DebugView        {            private Company2 m_Company2;            //必须要有一个构造函数，包含目标类型            public Company2DebugView(Company2 company2)            {                m_Company2 = company2;            }            public string Employees            {                get                {                    return String.Join(" | ", m_Company2.employeeNames.ToArray());                }            }        }        private string name = "Company2";        private List
     
       employeeNames = new List
      
       () { "Employee1", "Employee2", "Employee3" };    }
