Trying to pass C# DateTime to Crystal Reports where DateTime is used in rpt query

Hello,

I am trying to pass a C# DateTime object programatically to a report where that datetime is used in a Crystal Reports selection clause. A snippet of the code is as follows:

I can't get cut and paste to work in this window so bear with me.

report.SetParameterValue(0, assetID);

report.SetParameterValue(1, mPassTerminationNotification.PassStartTime.ToString());

report.SetParameterValue(2, mPassTerminationNotificaiton.PassEndTime.ToString());

report.SetParameterValue(3, passID);

report.ExportToDisk(ExportFormatType.Excel, filename);

Crystal Reports get these parameters and does a where clause and the DateTime seem to be the issues.

{Asset.Asset_Name} = {?@assetID} and

{Pass.Pass_ID} = {?@passID} and

{Alert.Alert_DateTime} >= {?startTime} and   //This line is the issue

{Alert.Alert_DateTime} <= {?endTime} and  //This line is the issue

isnull({Alert.Measurand_Index})

When run it throws an exception Unable to connect:  Incorrect log on parameters

Note rpt file goes to a Table query thorugh an ODBC connection.

Report runs fine when running through Crystal Reports 2011 directly.

PS.  I tried removing the two lines above and it ran.     I also tried sending the C# DateTimes without the ToString() and it resulted in the same error.

Any assistenace would be greatly appreciated. Also if you know a way to cut and paste into this forum that would be helpful as well.
