C# SSRS日期时间参数默认值格式

我有一个asp.net应用程序，允许用户为SSRS报告创建订阅

我的所有报告都有@StartDate和@EndDate参数，其默认值为

=Today.AddDays(-14) 

及

分别

我的c代码在加载订阅表单时检查参数的默认值，以预填充AspxDateEdit控件。这一切都可以在我的开发环境（新西兰）上正常工作

最初的网站将驻留在澳大利亚的服务器上，随后将向世界各地的各个国家推出，因此我需要保持DateTimes的格式动态（特定于文化）

在实时系统上加载报表的订阅表单时，我收到错误“字符串未被识别为有效的日期时间”。转储参数值。DefaultValues[0]显示AU服务器上的默认值为US格式（MM/dd/yyyy），这导致了错误。日志代码：

SQLReportsLogic.Log(MyLog, "(Line 599 - LoadParams)Default Param Value:" + Rp.DefaultValues[0] + "/ ServerDateFormatToday:" + DateTime.Now);

结果输出：

(Line 599 - LoadParams)Default Param Value:3/24/2015 12:00:00 AM/ ServerDateFormatToday:24/03/2015 7:14:47 AM

格式应与服务器的区域性信息一致，即dd/MM/yyyy

-   The report language is set to User!Language
-   The Server System Locale is English(Australia)
-   The Server Location is Australia
-   The Server Datetime format is set to ShortDate=d/MM/yyyy LongDate=dddd, d MMMM yyyy
-   The Server Language is set to English (Australia)
-   The Reporting Services Service is running under Local System Account
-   WWW is running under Local System Account
-   SSRS is running in Native Mode

当确定=Today（）的格式时，SSR具体从何处获取日期时间格式？据我了解，到目前为止，这应该是以系统指定的dd/MM/yyyy格式生成的=Today（） 我还尝试将参数的DefaultValue格式化为

-   “yyyy/MM/dd hh:mm:ss” = The DefaultValue expression for the report parameter ‘StartDate’ contains an error: Input string was not in a correct format
-   “yyyy/MM/dd hh:mm” = The DefaultValue expression for the report parameter ‘StartDate’ contains an error: Input string was not in a correct format
-   “yyyy/MM/dd” = The DefaultValue expression for the report parameter ‘StartDate’ contains an error: Input string was not in a correct format
-   DateFormat.ShortDate = The property ‘DefaultValue’ of report parameter ‘StartDate’ doesn’t have the expected type.
-   DateFormat.LongDate = The property ‘DefaultValue’ of report parameter ‘StartDate’ doesn’t have the expected type.
-   DateFormat.GeneralDate = The property ‘DefaultValue’ of report parameter ‘StartDate’ doesn’t have the expected type.

除非我能解决SSRS呈现=Today（）的方式，否则我的手似乎被束缚住了。据我所知，我需要找出SSRS安装使用不正确区域性的问题？它在什么地方查过了吗

我正在使用VS2012（11.0.61030.00更新4）和SSDTBI插件（MSSQL Server Reporting Services Designers版本11.0.3436.0）

最终找到了要使用的正确搜索词，并在两天后找到了解决方案-如本文所述覆盖SSRS GetWebRequest。。

公共部分类ReportingService:DevReportService.ReportingService 2010
{
/// 
///获取或设置生成报表时使用的区域性。
/// 
///生成报告时使用的区域性。
公共文化信息文化{get；set；}
受保护的覆盖WebRequest GetWebRequest（Uri）
{
WebRequest=base.GetWebRequest（uri）；
CultureInfo culture=this.culture？？CultureInfo.CurrentCulture；
request.Headers.Add（HttpRequestHeader.AcceptLanguage，culture.Name）；
返回请求；
}
}

我们能看到抛出此

格式异常的代码吗？您的文化设置是什么？谢谢Soner，我已经在问题中添加了代码，我的文化在web中设置为中性。很好的答案！对此的一个增强是创建一个新类，该类将DevReportService.ReportingService2010作为父类，以防将来重新生成WSDL CS文件
