Invalid Parameter Value while programmatically rendering report

[Thomas]

I'm using Q1 2012 for an MVC 3 Application where a report is generated, attached to an email and sent.  The parameters are applied from an object model containing all report parameters and strings representing each value.  When applying the value in plain text, the report runs and attaches to the email as it should
EX.
Report.ReportParameter.Value[0] = "Value"

But when doing the same from the model, I receive an inner exception for an invalid parameter

Working Code:
rpt.ReportParameters[4].Value = Reporting.GetParametersObject("VAL1; VAL2");

But when the code is changed to this:
rpt.ReportParameters[4].Value = Reporting.GetParametersObject(email.EmailReportParameters.ToString());

I receive and inner exception error and the parameter value returns to null.

The GetParametersObject converts a string to an Object[].

The debugger shows the same values in both cases as type {string[]}

Model: (I've also tried an Object[] for EmailReportParameters with the same result)

public class EmailReport
    {
        public string EmailAddress { get; set; }
        public string EmailAttachmentExtension { get; set; }
        public string EmailAttachName { get; set; }
        public string EmailSubject { get; set; }
        public string EmailBody { get; set; }
        public String[] EmailReportParameters { get; set; }
    }

Single value parameters are working properly:
rpt.ReportParameters[0].Value = email.EmailReportParameters[0];

Error Detail:

InnerException   {"Invalid value of report parameter 'LineOfBusiness1'."}

Hello Thomas,

It will be best to send us a running sample that exhibits your issue. We were unable to reproduce such a problem at our end and your code seems to be ok. However we cannot be sure as we do not know your full source code.

Having in mind the error, you may be trying to export a report with empty parameters for example (if the string has no values in it - please check if there are values in the array at all times and also at the right time).

Regards,
IvanY

Thanks for looking into this.  I found my issue.

When the parameters were collected from the Parameters table, it contained invisible characters.  I used a regex to cleanup the strings before applying them to the procedure.
