连接数据库coreDB,向表myBBS中插入文章。表myBBS的定义如下：
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[myBBS]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [dbo].[myBBS]
GO

CREATE TABLE [dbo].[myBBS] (
 [ID] [bigint] IDENTITY (1, 1) NOT NULL ,
 [Title] [char] (160) COLLATE Chinese_PRC_CI_AS NULL ,
 [Author] [char] (20) COLLATE Chinese_PRC_CI_AS NULL ,
 [Date_of_Created] [datetime] NULL ,
 [Abstract] [char] (480) COLLATE Chinese_PRC_CI_AS NULL ,
 [Content] [ntext] COLLATE Chinese_PRC_CI_AS NOT NULL
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
GO

TextBox1,TextBox2分别为提供用户输入标题和文章内容的两个textBox,
用户点击Button1按钮时检查并保存文章到数据库中。

  private void Button1_Click(object sender, System.EventArgs e)
  {
   SqlConnection coreDB=new SqlConnection();
   coreDB.ConnectionString= "workstation id=/"GQA-ERIC-LV/";packet size=4096;integrated security=SSPI;" +
    "data source=/"gqa-eric-lv/";persist security info=False;initial catalog=CoreDB";

   string Title=TextBox1.Text;
   string Content=TextBox2.Text;
   if(Title.Trim()==""||Content.Trim()=="")return;

   string mySelectQuery =@"insert into myBBS (Title,Content) Values('"+ Title +  "','"  +Content+"')";
   SqlCommand myCommand = new SqlCommand(mySelectQuery,coreDB);

   coreDB.Open();
   SqlDataReader myReader = myCommand.ExecuteReader();
   myReader.Close();
   coreDB.Close();
  }
