昨晚有学点新知识，是有关C# 6.0的。

在数据库创建有一张表：

CREATE TABLE [dbo].[ToolLocation]( [ToolLocation_nbr] SMALLINT IDENTITY(1,1) NOT NULL PRIMARY KEY, [LocationName] NVARCHAR(20) NOT NULL, [Description] NVARCHAR(50) NULL, [IsActive] BIT NOT NULL DEFAULT(1))GOSource Code

看看前后对比与写法：

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;namespace Insus.NET.Models{ public class ToolLocation {  public short ToolLocation_nbr { get; set; } = 1;  public string LocationName { get; set; } = string.Empty;  public string Description { get; set; } = string.Empty;  public bool IsActive { get; set; } = true; }}Source Code

下面Insus.NET演示一下，创建一个实体：

using Insus.NET.Models;using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;namespace Insus.NET.Entities{ public class ToolLocationEntity {  public IEnumerable<ToolLocation> ToolLocations()  {   return new List<ToolLocation>() {    new ToolLocation(),    new ToolLocation { ToolLocation_nbr = 2, LocationName = "A2", Description = "A2 CNC",IsActive = true},    new ToolLocation { ToolLocation_nbr = 3, LocationName = "C4", Description = "C4 CNC",IsActive = false}   };  } }}Source Code

它将会有三个对象，第一个对象是使用默认值。
在控制器中：
