[ASP.net教程]C# 6.0的属性(Property)的语法与初始值


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))GO

Source 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:

 

在ASP.NET MVC视图中,显示这些数据:

 

看看运行的效果:
