向数据库直接插入数据

  string strConn = "Data Source=.;Initial Catalog=PB_NewsSystem;Integrated Security=true";//创建数据库连接对象
        SqlConnection conn = new SqlConnection(strConn);//建立SqlConnection数据库和应用的桥梁
        try
        {
            conn.Open();//打开数据库
            SqlCommand cmd = new SqlCommand();////执行sql语句 和connection对象
            cmd.Connection = conn;//创建连接
            string sqlStr = "insert into [News] ([NewsTitle],[NewsContent]) values (@NewsTitle,@NewsContent)";//执行sql语句
            cmd.CommandText = sqlStr;//代表执行的是SQL语句
            cmd.Parameters.Add(new SqlParameter("@NewsTitle", this.txtTitle.Text));
            cmd.Parameters.Add(new SqlParameter("@NewsContent", this.txtContent.Text));
            cmd.ExecuteNonQuery();//执行向数据库插入一条数据
            this.lblMsg.Text = "添加成功！";
        }
        catch
        {
            this.lblMsg.Text = "添加失败！";
        }
        finally
        {
            conn.Close();
        }
