求助 把下面一段—elphi）代码 编译成C#形式

Delphi(Pascal) code

Delphi, CB：procedure TFPProcess.SaveFPData(AQuery: TADOQuery; AFingerID: Integer; AFPData: OleVariant);var  pData: PChar;begin  with AQuery do begin    Close;    SQL.Clear;    SQL.Add('SELECT * FROM zkFingerPrint WHERE FingerID = ' + IntToStr(AFingerID));    Open;    if IsEmpty then      Append    else      Edit;    FieldByName('FingerID').Value := AFingerID;    //保存指纹模板    with TBlobStream(CreateBlobStream(FieldByName('Template'), bmWrite)) do begin      pData := VarArrayLock(AFPData);      try        Write(pData^, VarArrayHighBound(AFPData, 1) - VarArrayLowBound(AFPData, 1) + 1);      finally        VarArrayUnlock(AFPData);      end;      Free;    end;    Post;    Close;  end;end;procedure TFPProcess.GetFPData(AQuery: TADOQuery; AFingerID: Integer; var AFPData: OleVariant);var  pData: PChar;begin  with AQuery do begin    Close;    SQL.Clear;    SQL.Add('SELECT * FROM zkFingerPrint WHERE FingerID = ' + IntToStr(AFingerID));    Open;    //读取数据    if not IsEmpty then       with TBlobStream(CreateBlobStream(FieldByName('Template'), bmRead)) do begin         AFPData := VarArrayCreate([0, Size + 1], varByte);         pData := VarArrayLock(AFPData);         try           Read(pData^, Size);         finally           VarArrayUnlock(AFPData);         end;         Free;       end;    Close;  end;end;

最少能把主体部分翻译出来，分不够你说我可以加，但一定要翻译正确

不过记得，添加最好用SqlCommand来做
