主题：'#' 附近有语法错误。

Dim y As Integer = Date.Today.Year
Dim m As Integer = Date.Today.Month
Dim dt1 As New Date(y, m, 1)
Dim dt2 As New Date(y, m, Date.DaysInMonth(y, m)) '获取本月的最后一天
Dim Filter As String
Filter = "开piao日期 >= #" & dt1 & "# And 开piao日期 <= #" & dt2 & "#"
DataTables("统计_Table1").LoadFilter = Filter '设置加载条件
DataTables("统计_Table1").Load() '

窗口按钮提示“'#' 附近有语法错误。”什么问题，谢谢
