在vb.net中搜索方括号字符串

Question

iam making a dictionary in mediawiki and for this purpose i designed a bot in vb.net when i search in a string which contains [[ code dosne detect the [[ in a string a seems it bypass the [[ code is below

 dbCommand.CommandText = "SELECT * FROM data"
            dbCommand.Connection = dbConn
            dbConn.Open()
            Dim dbDR As OleDb.OleDbDataReader = dbCommand.ExecuteReader

            While dbDR.Read
                Dim mydata As String = CStr(dbDR("mean".ToString))
                If InStr(mydata, vbNewLine & "[[اسم نکرہ]]") Then
                    Dim myid As String = dbDR("ID".ToString)
                    ListBox1.Items.Add(mydid)
                End If
            End While

this code search for vbNewLine & "[[اسم نکرہ]]" in the string and then add myid to listbox but it search "اسم نکرہ" also (without [[) so it mix up. where iam making mistake?

Answer 1

Use : dbCommand.CommandText = "SELECT * FROM data WHERE mean like '%[[اسم نکرہ]]%'" Note some old ms access version dont support % in like query so use *

so you are filtering data from it source, no need to filter it in VB.net
