C#（winform）调用AcReport文档

1、引用AcReport.dll组件

2、注册组件

        /// <summary>
        /// 注册组件
        /// </summary>
        AcReport.AcRptEngine mac;
        private void SetAcRegisterInfo()
        {
            int ErrCode = 0;
            string ErrMsg = "";
            mac.SetRegisterInfo("280853595D4033132E36CC85879681948B9690A4978D8A85CA878B89C49595DED5D2D1D1D7D" +
            "3D7DCD1DDCDD6D78680D8AD0CFAADC1DDF8F566934E1BAD6B8B296DB4BC968283E9F8FE23728EF0F71F9417C40DB6D30C729ECD01D774746D80E3EE321C6D",

                "天方工作室(acreport@sina.com qq:1655373859)", "23bd", "", "", "", "", ref ErrCode, ref ErrMsg);
            if (ErrCode != 0)
                MessageBox.Show(ErrMsg);
        }

3、窗体加载时候初始化：注册AcReport组件

 ReportPath = System.IO.Path.GetDirectoryName(Application.ExecutablePath);
 mac = new AcReport.AcRptEngine();
 SetAcRegisterInfo();

  实例化一个AcRptEngine对象，AcReport中只有一个实例化对象AcRptEngine。

4、定义dapper访问数据库

        static string sqlconnectionString = ConfigurationManager.ConnectionStrings["constr"].ToString();//获取App.config中的连接字符串
        public static SqlConnection SqlConnection()
        {
            var connection = new SqlConnection(sqlconnectionString);
            connection.Open();
            return connection;
        }

 5、查询数据

            var conn = SqlConnection();
            string sql = "select  * from [User]";
            var list = conn.Query<UserInfo>(sql).ToList();

 6、构建内存表

            if (mac.CustDataBuilder.TableExist("person"))//判断内存表名是否存在，存在就移除，避免数据重复
            {
                mac.CustDataBuilder.RemoveTable("person");                
            }
            mac.CustDataBuilder.NewTable("person");
            mac.CustDataBuilder.AddStringField("person", "Account", 20);
            mac.CustDataBuilder.AddStringField("person", "RealName", 30);
            mac.CustDataBuilder.OpenTable("person");

 7、内存表中添加数据

            
            //待解决问题：清空内存表数据 
            foreach (var item in list)//将查询到的数据循环添加到内存表中
            {
                mac.CustDataBuilder.AppendEmptyRow("person");
                mac.CustDataBuilder.SetFieldValue("person", "Account", item.Account);
                mac.CustDataBuilder.SetFieldValue("person", "RealName", item.RealName);
            }
            
            string path = ReportPath + @"
eportsuser.apt";//设置数据模板路径
            mac.ShowDesigner();//调用设计器，设计模板
            mac.LoadFromFile(path);//加载模板
            mac.Preview();//预览模板
