epplus复制工作表报错

[talklion]

尝试用epplus把工作表添加到另外一个工作簿.如果工作表中没有包含图片可以成功复制。但是如果包含图片就提示参数不能为null，有见过类似的吗？

Imports Spire.Xls

Namespace CopyWorksheet_XLS
    Class Program
        Private Shared Sub Main(ByVal args As String())

            Dim workbook1 As Workbook = New Workbook()
            workbook1.LoadFromFile("sample1.xlsx")
            Dim sheet1 As Worksheet = workbook1.Worksheets(0)
            Dim workbook2 As Workbook = New Workbook()
            workbook2.LoadFromFile("sample2.xlsx")

            Dim sheet2 As Worksheet = workbook2.Worksheets.AddCopy(sheet1)
            sheet2.Name = "copiedsheet"
            workbook2.SaveToFile("newsample2.xlsx")
        End Sub
    End Class
End Namespace

用的Spire.xls.dll来复制，带图片的工作表复制后没问题。参考：原文。
