1、复制粘贴EXCEL单元格，每粘贴一行，单元格内有几行（单元格内换行）会多出来几行空行是什么原因？如何修改代码？

工程项目下的清单表，在项目东南西北内，复制粘贴EXCEL表单元格到清单后，1、出现双引号；2、自动添加4行空白行。

2、复制粘贴EXCEL单元格，用代码解决EXCEL单元格内有换行问题，如何去掉双引号呢？

\'粘贴带有换行的EXCEL单元格

If e.control = True AndAlso e.keycode = keys.v Then

    \'执行代码

    Dim str As String = ClipBoard.GetText

    Dim nstr As String = ""

    Dim tempstr As String = ""

    Dim flag As Boolean = False

    For i As Integer = 0 To str.length - 1

        If str(i) = """" Then

            If i = 0 OrElse str(i-1) = chr(9) OrElse str(i-1) = chr(10) Then \'开始

                flag = True

            ElseIf i = str.length-1 OrElse str(i+1) = chr(9) OrElse str(i+1) = chr(13) Then \'结束

                tempstr = tempstr.Replace(chr(13), "")

                nstr &= tempstr

                tempstr = ""

                flag = False

            End If

        End If

        If flag = True Then

            tempstr &= str(i)

        Else

            nstr &= str(i)

        End If

    Next

    \'ClipBoard.SetText(nstr)

    ClipBoard.SetText(nstr.trim(""""))

End If

1、测试的excel文件发上来。

2、具体说明赋值哪些数据，粘贴到哪些列出问题。截图说明。
