我在asp.net MVC中有一个页面,它以波斯语获取日期时间并将其存储在圣诞节datetime的数据库中。我将我的文化改为波斯语以便用波斯语显示日期和时间,一切正常,我可以使用DateTime.Now在数据库中存储日期时间,但是当我想从文本框中的用户获取日期时间(用户输入带有波斯语日期时间)并存储它时,我得到一个超出范围的错误说
将datetime2数据类型转换为日期时间数据类型会导致超出范围的值
我试图从FormCollection对象获取datetime值并将其转换为datetime,但我没有运气,
这是我的观点:
<form action="/Accounting/TempDocument/Insert" method="post" id="insert-form">
<div class="modal-body">
<div class="row">
<div class="form-body">
@Html.AntiForgeryToken()
<div class="form-group form-md-line-input">
@Html.LabelFor(m => m.Description, new { @class = "col-md-2 control-label" })
<div class="col-md-10">
@Html.TextAreaFor(m => m.Description, new { @class = "form-control", @placeholder = "Description" })
<div class="form-control-focus"> </div>
@Html.ValidationMessageFor(m => m.Description, "", new { @class = "help-block" })
</div>
</div>
<div class="form-group form-md-line-input">
@Html.LabelFor(m => m.DocumentDate, new { @class = "col-md-2 control-label" })
<!-- this block is for document date-->
<div class="col-md-10">
@Html.TextBoxFor(m => m.DocumentDate, new { @class = "form-control date-mask", @placeholder = "Document Date" })
<div class="form-control-focus"> </div>
@Html.ValidationMessageFor(m => m.DocumentDate, "", new { @class = "help-block" })
</div>
</div>
</div>
<!-- my form continues -->
这是我的行动:
[Route("Insert")]
[HttpPost]
public async Task<ActionResult> InsertAsync(AccountingDocument model, FormCollection collection)
{
try
{
// much code here
await _service.EntInsertAsync(model);
if (await _service.CommitAsync())
await SetResultMessageAsync("");
}
catch
{
}
return RedirectToAction("RenderTop");
}
我的global.asax类:
protected void Application_BeginRequest()
{
var persianCulture = new PersianCulture();
Thread.CurrentThread.CurrentCulture = persianCulture;
Thread.CurrentThread.CurrentUICulture = persianCulture;
}
最后我的persianCulture课程:
public class PersianCulture : CultureInfo
{
private readonly Calendar cal;
private readonly Calendar[] optionals;
public PersianCulture()
: this("fa-IR", true)
{
}
public PersianCulture(string cultureName, bool useUserOverride)
: base(cultureName, useUserOverride)
{
//Temporary Value for cal.
cal = base.OptionalCalendars[0];
//populating new list of optional calendars.
var optionalCalendars = new List<Calendar>();
optionalCalendars.AddRange(base.OptionalCalendars);
optionalCalendars.Insert(0, new PersianCalendar());
Type formatType = typeof(DateTimeFormatInfo);
Type calendarType = typeof(Calendar);
PropertyInfo idProperty = calendarType.GetProperty("ID", BindingFlags.Instance | BindingFlags.NonPublic);
FieldInfo optionalCalendarfield = formatType.GetField("optionalCalendars",
BindingFlags.Instance | BindingFlags.NonPublic);
//populating new list of optional calendar ids
var newOptionalCalendarIDs = new Int32[optionalCalendars.Count];
for (int i = 0; i < newOptionalCalendarIDs.Length; i++)
newOptionalCalendarIDs[i] = (Int32)idProperty.GetValue(optionalCalendars[i], null);
optionalCalendarfield.SetValue(DateTimeFormat, newOptionalCalendarIDs);
optionals = optionalCalendars.ToArray();
cal = optionals[0];
DateTimeFormat.Calendar = optionals[0];
DateTimeFormat.MonthNames = new[] { "فروردین", "اردیبهشت", "خرداد", "تیر", "مرداد", "شهریور", "مهر", "آبان", "آذر", "دی", "بهمن", "اسفند", "" };
DateTimeFormat.MonthGenitiveNames = new[] { "فروردین", "اردیبهشت", "خرداد", "تیر", "مرداد", "شهریور", "مهر", "آبان", "آذر", "دی", "بهمن", "اسفند", "" };
DateTimeFormat.AbbreviatedMonthNames = new[] { "فروردین", "اردیبهشت", "خرداد", "تیر", "مرداد", "شهریور", "مهر", "آبان", "آذر", "دی", "بهمن", "اسفند", "" };
DateTimeFormat.AbbreviatedMonthGenitiveNames = new[] { "فروردین", "اردیبهشت", "خرداد", "تیر", "مرداد", "شهریور", "مهر", "آبان", "آذر", "دی", "بهمن", "اسفند", "" };
DateTimeFormat.AbbreviatedDayNames = new string[] { "ی", "د", "س", "چ", "پ", "ج", "ش" };
DateTimeFormat.ShortestDayNames = new string[] { "ی", "د", "س", "چ", "پ", "ج", "ش" };
DateTimeFormat.DayNames = new string[] { "یکشنبه", "دوشنبه", "ﺳﻪشنبه", "چهارشنبه", "پنجشنبه", "جمعه", "شنبه" };
DateTimeFormat.AMDesignator = "ق.ظ";
DateTimeFormat.PMDesignator = "ب.ظ";
}
public override Calendar Calendar
{
get { return cal; }
}
public override Calendar[] OptionalCalendars
{
get { return optionals; }
}
}

我假设用户进入伊斯兰时代的那一年(当年是1438 AH)。
然后在数据库上发生错误The conversion of a datetime2 data type to a datetime data type resulted in an out-of-range value
,因为您的日期时间列使用datetime
类型而不是datetime2
。
datetime
T-SQL数据类型仅支持1753-01-01到9999-12-31范围内的日期。
将数据库上的数据类型更改为datetime2
,其中包含日期0001-01-01 00:00:00.0000000至9999-12-31 23:59:59.9999999。
答案 1 :(得分:0)
由于用户可能在Hijri日历中输入日期,因此它可能具有小于SQL datetime
支持的年份值(1753-01-01)。请注意,默认情况下,格里高利系统用于datetime
和{ datetime2
数据类型,无论是否设置了文化。
有一些可能的解决方案:
将数据库中映射列DocumentDate
的数据类型更改为datetime2,它支持最小值DateTime.MinValue
。
如果您将SqlCommand
与参数化查询结合使用,则可以在SqlDbType.DateTime2
或Parameters.Add
中将Parameters.AddWithValue
定义为数据库数据类型。
如果您将EF与EDMX一起使用,则可以通过将相应的列映射更新为DocumentDate
来定义属性DateTime2
。
