Parse String (yyyymmm) Format to DateTime?

问题

I have a field called Accounting Period as char, [AccountingPeriod] [char](6), how can I parse it to DateTime Format using DatePicker?

I used this KendoGrid for DatePicker

@(
    Html.Kendo().DatePicker()
        .Name(nameof(InvoiceDTO.AccountingPeriod))
        .Format("{0:yyyyMM}")
        .HtmlAttributes(new { @class = "form-control", style = "width:50%" })
)

I have the date: 199805

Okay, as from the comments I have understood that you have a date in "yyyyMM" format and from that you want the magical line of code to produce you an Object of type DateTime. You can do it using this line of code:

DateTime.TryParseExact("199805", "yyyyMM", CultureInfo.InvariantCulture, DateTimeStyles.None, out var theDate);

Feel free to modify it according to your needs.

UPDATE:

Regarding your assignment of the date to the Kendo datepicker, I would suggest you to create a method and call it inside of the Value() method. Something similar to this:

@functions{ 
    public DateTime GetDate(string strDate)
    {
        if (DateTime.TryParseExact(strDate, "yyyyMM", CultureInfo.InvariantCulture, DateTimeStyles.None, out var theDate))
        {
            return theDate;
        }
        return DateTime.Now;
    }
}

And then you can just call it inside the Value() method something like below:

@(
    Html.Kendo().DatePicker()
    .Name(nameof(InvoiceDTO.AccountingPeriod))
    .Value(GetDate(InvoiceDTO.AccountingPeriod)) // I assume AccountPeriod is of type string.
    // .Format("{0:yyyyMM}") I do not think we are going to need this after the date is parsed into the required type.
    .HtmlAttributes(new { @class = "form-control", style = "width:50%" })
)

PS: I have not tested the code, just fire in the air after going through this article. So, It might need some Love.
