here is the code I have in vb

  Public Overrides Sub Retrieve(Optional ByVal dr As DataRow = Nothing)
        Try
            If dr Is Nothing Then
                With MyBase.DataSet.Tables(MyBase.TableName)
                    dr = .Rows(MyBase.RowNumber)
                End With
            End If

            Select Case _intSelectFilter
                Case SelectFilters.All
                    _intVisitID = FieldToString(dr("iVisitID"))
                    _strClientID = FieldToString(dr("sClientID"))
                    _strVisitDate = FieldToDate(dr("dtVisitDate"))
                    '_intVisitTypeID = FieldToString(dr("iVisitTypeID"))
                    _strVisitType = FieldToString(dr("sVisitType"))
                    _intScoreMMSE = FieldToNumber(dr("iMMSE"))
                    _intScoreCornell = FieldToNumber(dr("iCornell"))
                    _intScoreGDS = FieldToNumber(dr("iGDS"))
                    _intScorePHQ9 = FieldToNumber(dr("iPHQ9"))
                    _decScoreGait = FieldToDecimal(dr("dGait"))
                    _intWeight = FieldToNumber(dr("iWeight"))
                    _intTimesHospitalized = FieldToNumber(dr("iTimesHospitalized"))

            End Select

        Catch exp As Exception
            Throw exp

I'm assuming FieldToXXXXX() are custom functions you wrote. Also, C# (as of current) does not have a concept of optional parameters. I overloaded the Retrieve function to simulate optional parameters.
public override void Retrieve(DataRow dr)

{

    try

    {

        if (dr == null)

        {

            dr = base.DataSet.Tables(base.TableName).Rows[base.RowNumber];

        }
 

        switch (_intSelectFilter)

        {

            case SelectFilters.All:

                _intVisitID = FieldToString(dr["iVisitID"]);

                _strClientID = FieldToString(dr["sClientID"]);

                _strVisitDate = FieldToDate(dr["dtVisitDate"]);

                //_intVisitTypeID = FieldToString(dr["iVisitTypeID"]);

                _strVisitType = FieldToString(dr["sVisitType"]);

                _intScoreMMSE = FieldToNumber(dr["iMMSE"]);

                _intScoreCornell = FieldToNumber(dr["iCornell"]);

                _intScoreGDS = FieldToNumber(dr["iGDS"]);

                _intScorePHQ9 = FieldToNumber(dr["iPHQ9"]);

                _decScoreGait = FieldToDecimal(dr["dGait"]);

                _intWeight = FieldToNumber(dr["iWeight"]);

                _intTimesHospitalized = FieldToNumber(dr["iTimesHospitalized"]);

                break;

        }

    }

    catch (Exception exp)

    {

        throw exp;

        //throw;   <<-- You may want to consider using "throw" by itself as it preserves the stack trace

    }

}
 

public override void Retrieve()  // Simulate optional parameter

{

    Retrieve(null);

}

try this:

It translates to 2 functions due to the optional parameter.

        public void Retrieve(){

            return Retrieve(null);

        }
 

        public void Retrieve( DataRow dr){

            try{

                if(dr == null){

                    dr = <NameOfMyParentClass>.DataSet.Tables(<NameOfMyParentClass>.TableName).Rows(<NameOfMyParentClass>.RowNumber);

                }

                switch (_intSelectFilter){

                    case SelectFilters.All:

                        _intVisitID = FieldToString(dr["iVisitID"]);

                        //Other rows in here translater similarly
 

                }

            }catch(Exception Exp){

                throw Exp;

            }

        }
