vb convert c#, passing parameter crystal rpts [*Resolved*]

Hello,

I have a vb code which l am trying to convert to c# and having many problems with it. PFD = rpt.DataDefinition.ParameterFields.Item("@dt"). In c# there is not a parameterFields method called Item. So i am not sure how do l get the name of my parameter that is in the crystal report viewer.

Can anyone help me convert this code to c#.

Code:

---

Imports CrystalDecisions.Shared
                Imports CrystalDecisions.CrystalReports.Engine
               
                Dim mDate As DataTime = #01/01/2005#
                Dim rpt As New CrystalReport1
                Dim PFD As ParameterFieldDefinition
                Dim PValues As ParameterValues
                Dim Parm As ParameterDiscreteValue

                PValues = New ParameterValues

                PFD = rpt.DataDefinition.ParameterFields.Item("@dt")
                Parm = New ParameterDiscreteValue
                Parm.Value = mDate
                PValues.Add(Parm)
                PFD.ApplyCurrentValues(PValues)

                CrystalReportViewer1.ReportSource = rpt

---

Thanks in advance,

Steve





Edit: Added [code][/code] tags for clarity. - Hack

Instead of .Item("@dt"), you could try just ["@dt"];

(without the .Item, and square brackets)

In VB.NET the Item property is often the default property, which means you can omit the property name, i.e.

VB Code:

PFD = rpt.DataDefinition.ParameterFields.Item("@dt")

could be written

VB Code:

PFD = rpt.DataDefinition.ParameterFields("@dt")

In C# the equivalent of a default property is an indexer. When using an indexer I believe that you MUST omit the property name, so the C# code becomes

Code:

---

PFD = rpt.DataDefinition.ParameterFields["@dt"];

---

Instant C# produces:

using CrystalDecisions.Shared;
using CrystalDecisions.CrystalReports.Engine;

public void test()
{
DataTime mDate = DateTime.Parse("01/01/2005");
CrystalReport1 rpt = new CrystalReport1();
ParameterFieldDefinition PFD = null;
ParameterValues PValues = null;
ParameterDiscreteValue Parm = null;

PValues = new ParameterValues();

PFD = rpt.DataDefinition.ParameterFields["@dt"];
Parm = new ParameterDiscreteValue();
Parm.Value = mDate;
PValues.Add(Parm);
PFD.ApplyCurrentValues(PValues);

CrystalReportViewer1.ReportSource = rpt;
}

Thanks for all your help.

PFD = rpt.DataDefinition.ParameterFields["dt"];

Have to take out the @ sign of an error message says field name does not exist.

Thanks,

Steve
