1. C#之 VS 自带 RDLC 报表学习,可参考学习 http://blog.csdn.net/hk_5788/article/details/49846905 2.代码片段 ///

/// 打印 ///

/// /// private void btnPrint_Click(object sender, EventArgs e) { try { string ticket = ""; string grossDatatime = ""; string str = "SELECT ticketno,grossdatetime from trade where cardno = @cardno and datastatus in (1,5) ORDER BY grossdatetime desc LIMIT 0,1"; MySqlDataReader reader = dbHelper.ExecuteReader(str, new MySqlParameter("@cardno", this.txtCardNo.Text.Trim().ToString())); if (reader.Read()) { } ticket = reader["ticketno"].ToString(); grossDatatime = reader["grossdatetime"].ToString(); reader.Close(); System.Data.DataTable table = new System.Data.DataTable(); table.Columns.Add("ticketNo", typeof(string)); table.Columns.Add("carNo", typeof(string)); table.Columns.Add("grossTime", typeof(string)); table.Columns.Add("grossWeight", typeof(string)); table.Columns.Add("tareWeight", typeof(string)); table.Columns.Add("netWeight", typeof(string)); table.Rows.Add(ticket, this.cboNo.Text.ToString(), grossDatatime, this.txtGrossWeight.Text.ToString(), this.txtTareWeight.Text.ToString(), this.txtNetWeight.Text.ToString()); FrmPound frm = new FrmPound(table);
