Dim caiyangs() As String = {"化学因素采样","化学因素现场检测采样","噪声强度采样","噪声脉冲采样","噪声个体采样","微波采样","振动采样","激光采样","电场磁场采样","紫外采样","超高频采样","高频采样","高温采样"}

Dim caiyy As New List(of String())

For Each caiyang As String In caiyangs

DataTables(caiyang).LoadFilter = "方案id = '" & fang("_id") & "'"

DataTables(caiyang).Load

Dim Arys As List(Of String())

Arys = DataTables(caiyang).GetValues("采样测量日期|采样员一确认","方案id = '" & fang("_id") & "' and 采样测量日期 is not null and 采样员一确认 is not null")

If Arys.Count > 0 Then

caiyy.AddRange(Arys) '出现错误

End If

错误提示：未能比较数组中的两个元素，如何修改正确的？

没看出来这个代码和【比较数组中的两个元素】有什么关系。截图并使用文字说明一下要做什么功能
