您好我在向部署在 ASP.NET 页面中的服务器上的 SSRS 报告提供参数时遇到错误。
请参考下面的代码，让我知道问题出在哪里？
ReportExecutionService rs = new ReportExecutionService();
string rptURL = System.Configuration.ConfigurationManager.AppSettings["rptURL"].ToString();
string rptPath = System.Configuration.ConfigurationManager.AppSettings["Page1SLScorecardReortForDownload"].ToString();
//Microsoft.Reporting.WebForms.ReportParameter[] paramlist = new Microsoft.Reporting.WebForms.ReportParameter[3];
//paramlist[0] = new Microsoft.Reporting.WebForms.ReportParameter("Week", "2013-05-03");
//paramlist[1] = new Microsoft.Reporting.WebForms.ReportParameter("year", "Fiscal Calendar 2013");
//paramlist[2] = new Microsoft.Reporting.WebForms.ReportParameter("Month", "Fiscal May, 2013");
ParameterValue[] paramlist = new ParameterValue[3];
//Microsoft.Reporting.WebForms.ReportParameter[] paramlist = new Microsoft.Reporting.WebForms.ReportParameter[3];
paramlist[0] = new ParameterValue();
paramlist[0].Name = "Week";
paramlist[0].Value = "2013-05-03";
paramlist[1] = new ParameterValue();
paramlist[1].Name = "year";
paramlist[1].Value = "Fiscal Calendar 2013";
paramlist[2] = new ParameterValue();
paramlist[2].Name = "Month";
paramlist[2].Value = "Fiscal May, 2013";
//ReportViewer1.ServerReport.SetParameters(paramlist);

rs.Url = rptURL;

rs.SetExecutionParameters(paramlist, "en-us");
String SessionId = rs.ExecutionHeaderValue.ExecutionID;
try

execInfo = rs.GetExecutionInfo();
}
