我正嘗試將水晶報表導出爲PDF。下面的代碼（顯然密碼和服務器名稱之類的東西已被更改，以保護無辜）...無法獲取水晶報表導出
public void RunReport(string outputFile, int cc, int yr, int wk)
{
ReportDocument rd = new ReportDocument();
rd.Load(FullFilePath("myreport.rpt"));
rd.Refresh();
rd.SetDatabaseLogon("userid", "password");
foreach (Table tbl in rd.Database.Tables)
{
tbl.LogOnInfo.ConnectionInfo.ServerName = "dbname";
tbl.LogOnInfo.ConnectionInfo.DatabaseName = "";
tbl.LogOnInfo.ConnectionInfo.UserID = "userid";
tbl.LogOnInfo.ConnectionInfo.Password = "password";
}
foreach (IConnectionInfo ci in rd.DataSourceConnections)
{
ci.SetLogon("userid", "password");
}
DiskFileDestinationOptions diskFileDestinationOptions = new DiskFileDestinationOptions();
ExportOptions exportOptions;
PdfRtfWordFormatOptions pdfFormatOptions = new PdfRtfWordFormatOptions();
diskFileDestinationOptions.DiskFileName = outputFile;
crExportOptions = rd.ExportOptions;
{
crExportOptions.ExportDestinationType = ExportDestinationType.DiskFile;
crExportOptions.ExportFormatType = ExportFormatType.PortableDocFormat;
crExportOptions.DestinationOptions = diskFileDestinationOptions;
crExportOptions.FormatOptions = pdfFormatOptions;
}
SetCurrentValuesForParameterField(rd, "IP_COMP_CODE", cc);
SetCurrentValuesForParameterField(rd, "IP_YEAR", yr);
SetCurrentValuesForParameterField(rd, "IP_WEEK", wk);
rd.Export();
}
private void SetCurrentValuesForParameterField(ReportDocument reportDocument, string paramFieldName, int value)
{
ParameterDiscreteValue parameterDiscreteValue = new ParameterDiscreteValue();
parameterDiscreteValue.Value = value.ToString();
ParameterValues currentParameterValues = new ParameterValues();
currentParameterValues.Add(parameterDiscreteValue);
reportDocument.DataDefinition.ParameterFields[paramFieldName].ApplyCurrentValues(currentParameterValues);
}
現在怪異的一部分，當我第一次寫這個代碼（以及它在SVN），它會給我一個COM異常，說它第一次執行導出（這是在ASP.NET MVC應用程序中）時內存不足，但所有後續導出（直到我重新啓動Web應用程序）才能正常工作。
錯誤產生的是：
First-chance exception at 0x75a2c41f in w3wp.exe: Microsoft C++ exception: _com_error at memory location 0x20dee4b0.
A first chance exception of type 'System.Runtime.InteropServices.COMException' occurred in CrystalDecisions.CrystalReports.Engine.dll
An exception of type 'System.Runtime.InteropServices.COMException' occurred in CrystalDecisions.CrystalReports.Engine.dll but was not handled in user code
Additional information: Memory full.
Failed to export the report.
我張貼在SAP的網站和他們的支持的人提供的，我包括了一些更改代碼，然後將其完全停止，錯誤如下工作：
An exception of type 'CrystalDecisions.CrystalReports.Engine.DataSourceException' occurred in CrystalDecisions.ReportAppServer.DataSetConversion.dll but was not handled in user code
Additional information: Failed to load database information.
Error in File myreport {6DC42165-A38A-4CB2-85FD-A77389827FA9}.rpt:
Failed to load database information.
當我恢復代碼更改時，它繼續給我這個錯誤（並且從此）。現在我根本無法導出報告。
的變化他建議導致了這樣的代碼：
ReportDocument rd = new ReportDocument();
rd.Load(FullFilePath("myreport.rpt"));
ConnectionInfo connectInfo = new ConnectionInfo()
{
ServerName = "dbname",
DatabaseName = "",
UserID = "userid",
Password = "password"
};
rd.SetDatabaseLogon("userid", "password");
foreach (Table tbl in rd.Database.Tables)
{
tbl.LogOnInfo.ConnectionInfo = connectInfo;
tbl.ApplyLogOnInfo(tbl.LogOnInfo);
}
現在SAP是說他們不會支持我，因爲我用VS.NET 2012年，即使我沒有使用任何VS. NET集成，簡單的SDK。他們已經非常無益。
我在Windows 7 64位上運行。我已經安裝的Crystal Reports SDK是：CRforVS_redist_install_64bit_13_0_4.zip，可從他們的網站獲得。
後端數據庫是Oracle，客戶端是11g。
我卸載並重新安裝了Oracle客戶端和Crystal Reports，但都沒有成功。我根本無法再導出報告。
