Question

我尝试使用REST API从其Office 365帐户检索用户的事件，但是按字段＆＃34; LastModifiedTime＆＃34;进行过滤。例如，检索在日期之后将发生的所有事件：＆＃39; 2014-09-19T03：45：30.4020439Z＆＃39;或者＆＃39; 2014-09-18T04：05：00Z＆＃39;但我总是检索此错误消息：

{
 "error": { 
   "code":"ErrorInternalServerError", 
   "message":"The binary operator GreaterThanOrEqual is not defined for the types
    ' Microsoft.Exchange.ExchangeSystem.ExDateTime' and 'System.DateTimeOffset'.",
   "innererror":{ 
     "message":"The binary operator GreaterThanOrEqual is not defined for the types 
          'Microsoft.Exchange.ExchangeSystem.ExDateTime' and 'System.DateTimeOffset'.",
     "type":"System.InvalidOperationException", 
     "stacktrace":" at 
          System.Linq.Expressions.Expression.GetComparisonOperator(ExpressionType 
          binaryType, String opName, Expression left, Expression right, Boolean 
          liftToNull)\r\n at 
          System.Linq.Expressions.Expression.GreaterThanOrEqual(Expression left, 
          Expression right, Boolean liftToNull, MethodInfo method)\r\n at 
          Microsoft.Exchange.Services.OData.Model.DataEntityFilterConverter.ConvertFilterNode(QueryNode queryNode)\r\n at Microsoft.Exchange.Services.OData.Model.DataEntityFilterConverter.

          Microsoft.Exchange.Services.OData.ODataCommand`2.Execute()\r\n at 
          Microsoft.Exchange.Services.OData.ODataTask.Execute(TimeSpan 
          queueAndDelayTime, TimeSpan totalTime)" 
    }
  }
}

以下是网址：

/Me/Events?$select=Subject,Start,End,LastModifiedTime&$filter=LastModifiedTime ge 2014-09-19T03:45:30.4020439Z

/Me/Events?$select=Subject,Start,End,LastModifiedTime&$filter=LastModifiedTime ge 2014-09-18T04:05:00Z

我认为我的错误是由日期格式引起的，但我不知道如何解决它。

请有人帮助我！

谢谢！

您可以尝试将日期值转换为类似于以下的datetimeoffset。

/Me/Events?$select=Subject,Start,End,LastModifiedTime&$filter=LastModifiedTime ge datetimeoffset'2014-09-19T03:45:30.4020439Z'

/Me/Events?$select=Subject,Start,End,LastModifiedTime&$filter=LastModifiedTime ge datetimeoffset'2014-09-18T04:05:00Z'

或者您可以使用演员操作

/Me/Events?$select=Subject,Start,End,LastModifiedTime&$filter=LastModifiedTime ge cast(2014-09-19T03:45:30.4020439Z, Edm.DateTimeOffset)

/Me/Events?$select=Subject,Start,End,LastModifiedTime&$filter=LastModifiedTime ge cast(2014-09-18T04:05:00Z, Edm.DateTimeOffset)

没有为类型＆＃39; Microsoft.Exchange.ExchangeSystem.ExDateTime定义二进制运算符GreaterThanOrEqual
