I have got an SQLite DB where I store a start and end value. These values are stored as a string (TEXT)

I have got an SQLite DB where I store a start and end value. These values are stored as a string (TEXT)

Return a valid DateTime string from a SQLite SELECT using DAPPER

I retrieve this data using the function below:

 public IEnumerable<CalendarEvent> GetEvents()
{
    return Get<IEnumerable<CalendarEvent>>(db =>
        db.Query<CalendarEvent>("SELECT Summary, strftime('%Y-%m-%d %H:%M:%S', Start) AS Start, " +
        "STRFTIME('%Y-%m-%d %H:%M:%S', End) AS End, " +
        "Description,GoogleEventId,Client_ID " +           
        "FROM CalendarEvent", CommandType.Text));
}

The result should be returned as a list of the model CalendarEvent. The models look like this;

public class CalendarEvent 
{
    public string Summary
    {
        get; set;
    } = string.Empty;

    public DateTime Start
    {
        get; set;
    } = DateTime.MinValue;

    public DateTime End
    {
        get; set;
    } = DateTime.MinValue;
    public string Description
    {
        get; set;
    } = string.Empty;
    public string GoogleEventID
    {
        get; set;
    } = string.Empty;

    public int Client_ID
    {
        get; set;
    } = int.MinValue;
}

The problem is the values for Start and End always have the value of DateTime.MinValue.

I somehow need a conversion, because if I don't use the strftime in the select and just use

SELECT Summary, Start, End, Description FROM CalendarEvent

A value of 14-11-2022 12:00 for example i开发者_开发知识库s throwing an invalid DateTime Exception because it tries to handle 14 as a month.

Does anybody have an idea what the best way to solve this is?
