我正在学习在visual basic 2008中使用sqlite数据库,我得到了以下教程代码.代码工作正常,我的问题是：这是什么意思！在代码中标记.请指出我在哪里可以获得更多信息,因为我希望了解更多信息.我安装了Windows Sdk v6.1.

Private Sub Button8_Click(ByVal sender As System.Object,ByVal e As System.EventArgs) Handles Button8.Click
    Dim DatabaseFilepath As String = "e:\sqlite.db3"

    Dim sqlconnect As New System.Data.sqlite.sqliteConnection()
    Dim sqlcommand As System.Data.sqlite.sqliteCommand

    sqlconnect.ConnectionString = "Data Source=" & DatabaseFilepath & ";"
    sqlconnect.Open()

    sqlcommand = sqlconnect.CreateCommand

    Dim SchemaTable = sqlconnect.GetSchema(System.Data.sqlite.sqliteMetaDataCollectionNames.Tables)

    For int As Integer = 0 To SchemaTable.Rows.Count - 1
        If SchemaTable.Rows(int)!TABLE_TYPE.ToString = "table" Then
            MessageBox.Show(SchemaTable.Rows(int)!TABLE_NAME.ToString())
        End If
    Next

    sqlcommand.Dispose()
    sqlconnect.Close()
End Sub

更新：

谁能告诉我代码中那个爆炸操作符的替代方法是什么？那个爆炸运算符看起来不寻常.
