c#学习笔记之命名空间

1.在c#文件头写using 语句

2.命名空间的别名例子：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Introduction = Gychan.Test;
namespace test
{
    class Program
    {
         static void Main(string[] args)
        {
           
            #region namespace
            Introduction::StudyExample test = new Introduction.StudyExample();
            Console.WriteLine(test.GetNameSpace());
            Console.ReadLine();
            #endregion
        }
     
        
    }
}
namespace Gychan.Test
{
    class StudyExample
    {
        public string GetNameSpace()
        {
            return this.GetType().Namespace;
        }
    }
}
