主题：多值字段自动更新的请教

 你是想问如何替换多值字段某个员工的值为空值是么？

 参考

Dim name As String = "张三"

For Each dr As DataRow In DataTables("表C").DataRows
Dim nstr As String = ""
    For Each s As String In dr("第一列").Split(",")
        If s = name Then
            'nstr &= "" & ","
        Else
            nstr &= s & ","
        End If
    Next
   
    dr("第一列") = nstr.Trim(",")
Next
