如何操作#REF！值

Question

我需要从Excel收集数据并将GridView填充为作业。我被困在一个值#REF!的列上，它返回一个负值-237823429。

我试图用此循环替换value.ToString

Dim SpecialChars As String = "~!@#$%^&*()|?{}[]<>"
Dim tempString As String = xlWorkSheet.Cells(i, 22).Value.ToString
For c As Integer = 0 To SpecialChars.Length - 1
    tempString.Replace(SpecialChars.Chars(c), "")
Next

仍然不知道该怎么办
