• 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:
