如何使用C＃将水晶报告中的日期时间格式转换为日期格式？

Question

我正在使用c＃windows窗体应用程序，也在水晶报表中。我正在从数据库中以datetime格式重新审核日期，但我只想在报告中显示日期，水晶报告中的任何公式字段都对我有帮助。这个问题谢谢。

Answer 1

If the datetime is in field (not a formula) then you can format it:

1. Right click on the field -> Format Editor
2. Date and Time tab
3. Select date/time formatting you desire (or click customize)

If the datetime is in a formula:

ToText({MyDate}, "dd-MMM-yyyy")
//Displays 31-Jan-2010

or

ToText({MyDate}, "dd-MM-yyyy")
//Displays 31-01-2010

or

ToText({MyDate}, "dd-MM-yy")
//Displays 31-01-10

etc...

Answer 2

In crystal report formulafield date function aavailable there pass your date-time format in that You Will get the Date only here

Example: Date({MyTable.dte_QDate})

Answer 3

In case the formatting needs to be done on Crystal Report side.

Simple way.

Crystal Report Design Window->Right click on the date field->format Field->Customize the date format per your need.

Works effectively.

Answer 4

This formula works for me:

// Converts CR TimeDate format to AssignDate for WeightedAverageDate calculation.

Date( Year({DWN00500.BUDDT}), Month({DWN00500.BUDDT}), Day({DWN00500.BUDDT}) ) - CDate(1899, 12, 30)

Answer 5

在选择公式中试试这个

Date(Year({datetimefield}), Month({datetimefield}), Day({datetimefield}))

Answer 6

有时字段不会被水晶报表识别为DATE，因此您可以添加一个带有函数的公式：Date（{YourField}），并将其添加到报表中，现在当您打开格式对象对话框时，您会发现日期格式选项。

Answer 7

如果它只是一个格式问题使用ToShortDateString()

Answer 8

There are many ways you can do this. You can just use what is described here or you can do myDate.ToString("dd-MMM-yyyy"); There are plenty of help for this topic in the MSDN documentation.

You could also write you own DateExtension class which will allow you to go something like myDate.ToMyDateFormat();

    public static class DateTimeExtensions
    {
        public static DateTime ToMyDateFormat(this DateTime d)
        {
            return d.ToString("dd-MMM-yyyy");
        }
    }
