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:
