将字符串(yyyymmm)格式解析为DateTime? [英] Parse String (yyyymmm) Format to DateTime?

问题描述

我有一个称为会计期间"的字段，为char，[AccountingPeriod] [char](6)，如何使用DatePicker将其解析为DateTime格式?

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

我将此KendoGrid用于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%" })
)

我有日期:199805

推荐答案

好的，从注释中我了解到，您有一个日期为"yyyyMM"格式的日期，并且您希望通过神奇的代码行生成一个类型为DateTime的对象.您可以使用以下代码行做到这一点:

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);

可以根据您的需要随意进行修改.

Feel free to modify it according to your needs.

更新:

关于将日期分配给Kendo日期选择器的问题，建议您创建一个方法并将其在Value()方法内部调用.与此类似:

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;
    }
}

然后您可以在Value()方法内部调用它，如下所示:

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%" })
)
