ASP.NET C＃reportviewer參數

Question

我是新來報告viwer，我想知道如何將select參數傳遞給報表查看器和數據源？我需要將開始日期和結束日期傳遞給數據源以過濾數據，並在報告查看器中顯示。任何人建議？

Answer 1

通過後面的代碼，這樣的：

ReportParameter[] parameters = new ReportParameter[yournumberofparamaters]; 
parameters[0] = new ReportParameter("name", value); 
parameters[1] = new ReportParameter("name", value); 
parameters[2] = new ReportParameter("name", value); 
this.Log_ReportViewer.LocalReport.SetParameters(parameters);
