下面这段代码复制到命令窗口,如果:
1、Find("[第二列] Like \'%J%\'") ,则可以正确运行。
2、替换成随机变量,Find("[第二列] Like \'% & vs(Rand.Next(0,vs.Count-1)) & %\'") ,或Find("[第二列] Like \'% & v1 & %\'"),
则不出结果。如何解决?
我的目的是这样的:
1、随机从中声母中选取一个声母。
2、从第二列中找到这个声母的行,以便引用本行相关数据。

Dim value() As String = {"Q","K","D","T","J","G","Y","F","S","Sh","R","L","N","B","P","W","M","Z","Zh","H","C","Ch","X"}
Dim v1 As String
Dim idx As Integer
Dim nList As new List(of String)
Dim vs As new List(of String)
vs.AddRange(Value)
idx = Rand.Next(0,vs.Count-1)
v1 = vs(idx)
msgbox(v1)

Dim dr As DataRow
\'dr = DataTables("表A").Find("[第二列] Like \'%J%\'")  \'正确运行
\'dr = DataTables("表A").Find("[第二列] Like \'% & vs(Rand.Next(0,vs.Count-1)) & %\'") \'不报错,但也得不到正确结果.
dr = DataTables("表A").Find("[第二列] Like \'% & v1 & %\'") \'不报错,但也得不到正确结果.
If dr IsNot Nothing Then
    Dim wz As Integer = Tables("表A").FindRow(dr)
    If wz >= 0 Then
        Tables("表A").Position = wz
        dr("第四列") = 999
    End If
End If

修改成这样,可以了:
dr = DataTables("全脑汉码声韵数字映射规则表").Find("第二列 like  " & "\'%" & v1 & "%\' " & " Or 第三列 Like  " & "\'%" & v1 & "%\' ")
