微软报表

using Microsoft.Reporting.WinForms;

1 创建报表文件TagsReport.rdlc

2 从工具箱拖一个table放在报表上，会自动配置数据源，建立dataset，可以选数据库，连接表，也可以选程序里的对象如ControlEase.AI.DataRecord.Record

报表左侧的工具箱data source中就有了dataset,可以将每个字段拖到报表的表格中，也可以在报表的表格中智能感知添加列,此处的dataset的名字很重要，代码控制导出到excel时，名字不对就出错

3 选择报表单元格设置前景背景颜色，在弹出的配色窗口中选择公式，在其中填入“=Iif(RowNumber(Nothing) Mod 2, "PaleGreen", "White")  "设置行颜色交替变化

4 代码控制输出excel

public void Export(IEnumerable<Tuple<string, object, DateTime, int>> tagValues, string path)
        {
            //Guard.ArgumentNotNull(values, "values")
            //     .ArgumentStringNull(Filename, "Filename")
            //     .ArgumentNotNull(Culture, "Culture");

            IList<AI.DataRecord.Record> recordList = new List<AI.DataRecord.Record>();
            foreach (var tupl in tagValues)
            {
                recordList.Add( AI.DataRecord.Record.FromTuple(tupl));
            }
            var values = recordList.GetEnumerator();
            string temp = GetTempFile();
            FileInfo fileInfo = new FileInfo(temp);        
            try
            {          
                List<ReportParameter> parameters = new List<ReportParameter>(); 
                parameters.Add(new ReportParameter("Name", "Name"));        
                parameters.Add(new ReportParameter("Date", "Date"));
                LocalReport report = new LocalReport();
                report.ReportEmbeddedResource = "ControlEase.Inspec.HistoryDataRecord.Presentation.TagsReport.rdlc";
                report.SetParameters(parameters);
                Warning[] warnings;
                string[] streamids;
                string mimeType;
                string encoding;
                string extension;
                report.DataSources.Add(new ReportDataSource("TagsReport", values));

//bool ok = report.IsReadyForRendering;//true 才能Render
                byte[] bytes = report.Render("EXCEL", null, out mimeType, out encoding, out extension,
                 out streamids, out warnings);

                using (FileStream stream = new FileStream(temp, FileMode.CreateNew))
                {
                    try
                    {

                        stream.Write(bytes, 0, bytes.Length);
                        stream.Close();
                    }
                    catch (Exception e)
                    {
                        e.ToString();
                    }
                }

                File.Copy(temp, path, true);
            }
            catch (Exception e)
            {
                //throw e;
            }
            finally
            {
                //if ( excel != null )
                //    excel.Dispose ( );
            }
        }
        /// <summary>
        /// Get temp excel file name
        /// </summary>
        /// <returns></returns>
        static string GetTempFile()
        {
            string file = Path.GetRandomFileName();
            file = Path.ChangeExtension(file, ".csv");
            return Path.Combine(Path.GetTempPath(), file);
        }

冻结表头

在报表设计界面--table边框上鼠标右键--Tablix property---弹出新窗口设置----rows header :keep rows header visible while scrolling
