Error converting value \"02:30:40\" to type 'System.TimeOnly'-CodePudding

I am working a .net6.0 project (with postgreSql)

I want to save a start time and off time of the office into database.

I did this.

public class WorkingDay
{
    public int Id { get; set; }

    public DaysOfWeek Day { get; set; }  // enum

    public OpeningHours OpeningHours { get; set; }

    public bool IsworkingDay { get; set; }
}


public class OpeningHours
{
    public TimeOnly StartTime { get; set; }

    public TimeOnly OffTime { get; set; }

}

Now I send the data to create using POSTMAN.

{
    "Day" : 1,
    "OpeningHours" : {
        "StartTime":  "02:30:40", 
        "OffTime" :  "02:30:40"
    },
    "IsworkingDay" : false
}

I got below error. Error converting value \"02:30:40\" to type 'System.TimeOnly'. Path 'OpeningHours.OffTime',

How can I send the data for TimeOnly?

CodePudding user response：

DateOnly and TimeOnly are currently (.NET 6) not supported by System.Text.Json. However, they will be implemented in .NET 7, as by this github issue.

There are multiple workarounds for now.

convert them to DateTime or DateTimeOffset and back for serialization.
switch to .NET 7 preview for development
copy the .NET 7 implementation to your code (see the pull request)
write your own converter (an example of which can be found in this link)
