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]GOTextBox1,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(); }
