My code i have written:

 Dim paramFields As New ParameterFields
        Dim paramField As New ParameterField
        Dim discreteVal As New ParameterDiscreteValue

        paramField.ParameterFieldName = "Country"
        discreteVal.Value = "USA"
        paramField.CurrentValues.Add(discreteVal)

        paramField = New ParameterField
        discreteVal.Value = "Netherlands"

        paramFields.Add(paramField)
        Dim rpt As New MyReport

        CrystalReportViewer1.ParameterFieldInfo = paramFields
