1到Excel

首先将Microsoft.Office.Interop.Excel组件引用添加到项目中.这应该在Project中的.NET选项卡下 – >添加参考.
将using语句添加到表单中：

using Excel = Microsoft.Office.Interop.Excel;

添加一个按钮控件,并将此代码添加到它的正文中：

private void btnExport_Click(object sender,EventArgs e)
    {

        Excel.Application app = new Excel.Application();
        app.Visible = true;
        Excel.Workbook wb = app.Workbooks.Add(1);
        Excel.Worksheet ws = (Excel.Worksheet)wb.Worksheets[1];
        // changing the name of active sheet
        ws.Name = "Exported from gridview";

        ws.Rows.HorizontalAlignment = HorizontalAlignment.Center;
        // storing header part in Excel
        for (int i = 1; i < dataGridView1.Columns.Count + 1; i++)
        {
            ws.Cells[1,i] = dataGridView1.Columns[i - 1].HeaderText;
        }


        // storing Each row and column value to excel sheet
        for (int i = 0; i < dataGridView1.Rows.Count - 1; i++)
        {
            for (int j = 0; j < dataGridView1.Columns.Count; j++)
            {
                ws.Cells[i + 2,j + 1] = dataGridView1.Rows[i].Cells[j].Value.ToString();
            }
        }

        // sizing the columns
        ws.Cells.EntireColumn.AutoFit();

        // save the application
        wb.SaveAs("c:\\output.xls",Type.Missing,Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlExclusive,Type.Missing);

        // Exit from the application
       app.Quit();
    }
}

2 – 到sql Server

这不需要互操作.为了便于使用,将List对象传递给执行插入的事件.如果您将表设置为与网格视图列对应,则很容易.在这里,我使用了一个sproc.

private void btnTosql_Click(object sender,EventArgs e)
    {
        string connStr = @"Data Source=(local)\sqlexpress;Initial Catalog=rTALIS;Integrated Security=True";
        var cn = new sqlConnection(connStr);
        var cm = new sqlCommand("exec usp_InsertRecord",cn);
        cm.CommandType = System.Data.CommandType.StoredProcedure;
        try
        {
            cn.Open();
            foreach (Row r in rows)
            {
                cm.Parameters.Clear();
                cm.Parameters.AddWithValue("@Number1",r.Number1);
                cm.Parameters.AddWithValue("@Number2",r.Number2);
                cm.Parameters.AddWithValue("@Number3",r.Number3);
                cm.Parameters.AddWithValue("@Number4",r.Number4);
                cm.Parameters.AddWithValue("@Number5",r.Number5);
                cm.Parameters.AddWithValue("@Number6",r.Number6);
                cm.Parameters.AddWithValue("@Number7",r.Number7);
                cm.Parameters.AddWithValue("@Date1",r.Date1);
                cm.ExecuteNonQuery();
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
        }
        finally
        {
            cn.Close();
        }
    }

如果我需要为您调整此信息,请告诉我.在原始示例中,我有List rows = new List();在form_Load方法中声明.这适用于该解决方案,但它的范围现在太有限了.我已将它向上/向上移动到类中,以便可以在窗体上的任何位置调用(特别是btnTosql_Click).我在下面评论过：

List<Row> rows = new List<Row>();

    private void Form1_Load(object sender,EventArgs e)
    {
        //var rows = new List<Row>();  //limited scope
        var sr = new StreamReader(@"C:\so_test.txt");
        while (!sr.EndOfStream)
        {
            string s = sr.ReadLine();
            if (!String.IsNullOrEmpty(s.Trim()))
            {
                rows.Add(new Row(s));
            }
        }
        sr.Close();
        dataGridView1.DataSource = rows;
    }
