C#.net中转换成html页
Asp.net生成静态html文件
内容 一 表结构：
CREATE TABLE [dbo].[HtmlNews] (
[Id] [int] IDENTITY (1, 1) NOT NULL ,
[subject] [nvarchar] (50) COLLATE Chinese_PRC_CI_AS NOT NULL ,
[filename] [nvarchar] (50) COLLATE Chinese_PRC_CI_AS NOT NULL ,
[Addtime] [datetime] NULL
) ON [PRIMARY]
GO
ALTER TABLE [dbo].[HtmlNews] ADD
CONSTRAINT [DF_HtmlNews_Addtime] DEFAULT (getdate()) FOR [Addtime]
GO
