1、将文本中的数据导入到SQL数据库中。
2、把文本当数据库的使用，调用它里面的内容，实现功能
哪位大虾有这方面的事例，拿来看看。我叫要事例，麻烦不要给我说做的过程方法，因为急用。
希望能理解，再次十分感谢。

private void button3_Click_1(object sender, EventArgs e)
        {
            OpenFileDialog diag = new OpenFileDialog();
            diag.Filter = "*.txt|*.txt";
            diag.Title = "请选择你的txt文件";

            if (diag.ShowDialog() == DialogResult.OK)
            {

                    (
                    diag.FileName,
                    Encoding.Default   //txt用什么编码,ascii,gb2312,unicode

                }
