如何在以下情况下使用三元运算符？

问题描述

Hii，





objEmployeeAbsence.SunWorkingHour = dtProperRecord.Rows [i] [SunWorkingHour]。ToString（）== || dtProperRecord.Rows [i] [SunWorkingHour]。ToString（）==0？ null：上面代码中的Math.Round（float.Parse（dtProperRecord.Rows [i] [SunWorkingHour]。ToString（）），2）;



=> objEmployeeAbsence.SunWorkingHour中包含双数据类型。所以当我使用上面的类型条件时..如果它是真的，则不会设置null。如果我在那里使用0然后它取而不是空的





同时..如果我尝试使用if else块并尝试在objEmployeeAbsence.SunWorkingHour中指定null它被赋值..



这里是if else的代码

Hii ,


objEmployeeAbsence.SunWorkingHour = dtProperRecord.Rows[i]["SunWorkingHour"].ToString() == "" || dtProperRecord.Rows[i]["SunWorkingHour"].ToString() == "0" ? null : Math.Round(float.Parse(dtProperRecord.Rows[i]["SunWorkingHour"].ToString()), 2);

in the above code=> objEmployeeAbsence.SunWorkingHour has double datatype in it. so when i use above type condition .. null is not get set in it if its true. if i use 0 there then its taking but not the null


at the same time .. if i try to use if else block and try to assign null in objEmployeeAbsence.SunWorkingHour it gets assign ..

here is the code of if else

if (dtProperRecord.Rows[i]["SunWorkingHour"].ToString() == "" || dtProperRecord.Rows[i]["SunWorkingHour"].ToString() == "0")
                                        {
                                            objEmployeeAbsence.SunWorkingHour = null;
                                        }
                                        else
                                        {
                                            objEmployeeAbsence.SunWorkingHour = Math.Round(float.Parse(dtProperRecord.Rows[i]["SunWorkingHour"].ToString()), 2);
                                        }

我怎样才能做到这一点使用三元可能赋值null

how can i make this possible using ternary possible to assign null
