在CRM 2013插件获取日期与错误的时间，但UI没有时间字段.如何从日期中删除时间

本文关键字：时间 字段 没有时间 UI 删除 日期 插件 2013 CRM 获取 取日期 | 更新日期: 2023-09-27 18:11:23

我目前正在通过以下方式从CRM检索日期字符串

Entity dateDeliveryRequiredImage = (Entity)context.PostEntityImages["DeliveryRequired"];

这确实工作，但由于某种原因，它似乎是检索的时间，当我创建一个CSV文件通过以下行

dateDeliveryRequiredImage["requestdeliverby"].ToString()

有没有人知道它是从哪里得到时间的，因为没有地方输入时间(它说现在是晚上11点??)

更重要的是如何摆脱它

谢谢,肖恩

输入所需代码后出现以下错误

 if (!timeZoneCode.HasValue)
            return;

类型可转换为system的对象。需要Timeanddate 

var response = (LocalTimeFromUtcTimeResponse)_serviceProxy.Execute(request);

_serviceProxy在当前上下文中不存在

我的服务代码如下;

IPluginExecutionContext context = (IPluginExecutionContext)
            serviceProvider.GetService(typeof(IPluginExecutionContext));

        IOrganizationServiceFactory serviceFactory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
        IOrganizationService service = serviceFactory.CreateOrganizationService(context.UserId);

然而，输入服务或上下文没有任何作用

最后新QueryExpression (UserSettings.EntityLogicalName)

当前上下文中不存在用户设置

代码更新正常

private DateTime RetrieveLocalTimeFromUTCTime(DateTime utcTime, IOrganizationService service)
    {
        int? timeZoneCode = RetrieveCurrentUsersSettings(service);

        if (!timeZoneCode.HasValue)
            throw new Exception("Can't find time zone code");

        var request = new LocalTimeFromUtcTimeRequest
        {
            TimeZoneCode = timeZoneCode.Value,
            UtcTime = utcTime.ToUniversalTime()
        };
        var response = (LocalTimeFromUtcTimeResponse)service.Execute(request);
        return response.LocalTime;
        //var utcTime = utcTime.ToString("MM/dd/yyyy HH:mm:ss");
        //var localDateOnly = response.LocalTime.ToString("dd-MM-yyyy");
    }
    private int? RetrieveCurrentUsersSettings(IOrganizationService service)
    {
        var currentUserSettings = service.RetrieveMultiple(
        new QueryExpression("usersettings")
        {
            ColumnSet = new ColumnSet("localeid", "timezonecode"),
            Criteria = new FilterExpression
            {
                Conditions =
        {
            new ConditionExpression("systemuserid", ConditionOperator.EqualUserId)
        }
            }
        }).Entities[0].ToEntity<Entity>();
        return (int?)currentUserSettings.Attributes["timezonecode"];
    }

请注意与下面代码的不同之处在于:

}).Entities[0].ToEntity<Entity>();
return (int?)currentUserSettings.Attributes["timezonecode"];

在CRM 2013插件获取日期与错误的时间，但UI没有时间字段.如何从日期中删除时间

CRM将写入CSV之前可以删除的默认时间，如下所示:

DateTime dateAndTime = (DateTime)dateDeliveryRequiredImage["requestdeliverby"];
var date = dateAndTime.ToString("dd-MM-yyyy");

如果您想将默认时间写入CSV。你可以这样使用:

var date = dateAndTime.Date;

Dynamics CRM 2011以UTC时间存储所有DateTime字段，因此通过使用' DateTime。我们的日期将在到达数据库之前被转换成UTC时间。例如，默认时间是12:00:00，在数据库中它将被存储为11:00:00。这就是为什么你在你的插件中得到11PM。当我们的用户通过CRM读取日期时，它将被转换回当地时区，用户将读取正确的时间。

IPluginExecutionContext context = (IPluginExecutionContext)
        serviceProvider.GetService(typeof(IPluginExecutionContext));

IOrganizationServiceFactory serviceFactory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
IOrganizationService service = serviceFactory.CreateOrganizationService(context.UserId);
// This retrieves the UTC time
DateTime dateAndTime = (DateTime)dateDeliveryRequiredImage["requestdeliverby"];
// This converts the UTC time to your local time
var localDate = RetrieveLocalTimeFromUTCTime(dateAndTime, service);
// It will give you the correct date
var date = dateAndTime.ToString("dd-MM-yyyy");

将UTC转换为本地时间。请检查下面的代码:

    /// <summary>
    /// Retrive the local time from the UTC time.
    /// </summary>
    /// <param name="utcTime"></param>
    /// <param name="service"></param>
    private DateTime RetrieveLocalTimeFromUTCTime(DateTime utcTime, IOrganizationService service)
    {
        int? timeZoneCode = RetrieveCurrentUsersSettings(service);
        if (!timeZoneCode.HasValue)
            throw new Exception("Can't find time zone code");
        var request = new LocalTimeFromUtcTimeRequest
        {
            TimeZoneCode = timeZoneCode.Value,
            UtcTime = utcTime.ToUniversalTime()
        };
        var response = (LocalTimeFromUtcTimeResponse)service.Execute(request);
        return response.LocalTime;
        //var utcTime = utcTime.ToString("MM/dd/yyyy HH:mm:ss");
        //var localDateOnly = response.LocalTime.ToString("dd-MM-yyyy");
    }
    /// <summary>
    /// Retrieves the current users timezone code and locale id
    /// </summary>
    private int? RetrieveCurrentUsersSettings(IOrganizationService service)
    {
        var currentUserSettings = service.RetrieveMultiple(
        new QueryExpression("usersettings")
        {
            ColumnSet = new ColumnSet("localeid", "timezonecode"),
            Criteria = new FilterExpression
            {
                Conditions =
        {
            new ConditionExpression("systemuserid", ConditionOperator.EqualUserId)
        }
            }
        }).Entities[0].ToEntity<UserSettings>();
        return currentUserSettings.TimeZoneCode;
    }
