Dim tb As Table =Tables("资产负债表")

Dim tb2 As Table = Tables("总分类账")

Dim qj As String = Vars("会计期间")

Dim strs1() As String = {"货币资金"}

Dim strs2() As String = {"strs2(1)"}

Dim x() As String = {"0"}

Dim y() As String = {"6"}

'会计科目中提取'货币资金'的科目代码

For i As Integer = 0 To strs1.Length-1

Dim lst As List(of String) = DataTables("会计科目").GetValues("科目代码","资产负债表 like '" & strs1(i) & "%' or 资产负债表 like '%" & strs1(i) & " '")

Dim str As String

For Each ids As String In lst

str & = ids & ","

'msgbox(1)

str = str.Trim(",")

'msgbox(2)

Dim n As Double = tb2.DataTable.sqlCompute("sum(余额)","科目代码 in (" & str & ") And 摘要 = ' 本年累计' and 会计期间 = '" & Vars("会计期间") & "' ")

'msgbox(3)

tb(CInt(x(i)),CInt(y(i)))=n

'msgbox(4)

'output.show(strs2(i))

问题：当 strs1() 数组有多少值时，得到的最后：双精度小数，n，（例：第一个N为N1，第二N为N2，）

如何，进行最想N1 的值 -减去 N2的值；等运算操作？
