如何使用ews将任务的截止日期更新为none [英] How to update a task's due date to none using ews

问题描述

我尝试将任务的DueDate更新为none。但我得到以下错误。任何人都知道如何使用ews将DueDate设置为无。

谢谢，

错误信息：

我的代码：

//属性：截止日期更新

TaskType newDueDate = new TaskType （）;

if （task.DueDateUtc！= null ）

{

newDueDate.DueDate =（ DateTime ）task.DueDateUtc;

newDueDate.DueDateSpecified = true ;

}

else

{

newDueDate.DueDateSpecified = false ;

}

pathEndDate.FieldURI = UnindexedFieldURIType .taskDueDate;

updateDueDate.Item = pathEndDate;
