如何解决Sequence在CLOSEDXML中包含多个匹配元素的问题？

编程问答 2022-06-11

问题描述

我正在做的只是保存一个excel模板而不插入任何数据...
这是我的下面的代码。

Dim wb As XLWorkbook
wb = New XLWorkbook(rawfilelocation)
wb.SaveAs(filelocation,True) '---- I even tried false

我每次都会遇到此错误。

system.invalidOperationException: Sequence contains more than one matching element
   at System.Linq.Enumerable.SingleOrDefault[TSource](IEnumerable`1 source,Func`2 predicate)
   at ClosedXML.Excel.XLDataValidations.ProcessRangeRemoved(IXLRange range)
   at ClosedXML.Excel.XLDataValidations.Delete(IXLDataValidation dataValidation)
   at System.Collections.Generic.List`1.ForEach(Action`1 action)
