C# 使用C从MS sql将数据导出到microsoft excel

如何使用C将数据从MS-SQL导出到Microsoft Excel

---

有人能给我一个编码或相关教程的示例来连接到数据库并单击按钮导出到Microsoft Excel吗？

你知道吗，你可以在SQL Server Management Studio中通过右键单击数据库并选择“任务”->“导出数据”来实现这一点吗？

我在google中键入了你的确切问题标题，并找到了很多问题例句：除非你确切地问自己需要什么，否则时间不会给你答案。

            sda.Fill(dt);

                int ColumnsCount;

                if (dtReport == null || (ColumnsCount = dtReport.Columns.Count) == 0)

                    throw new Exception("ExportToExcel: Null or empty input table!\n");


                Microsoft.Office.Interop.Excel.Application Excel = new Microsoft.Office.Interop.Excel.Application();
                Excel.Workbooks.Add();

                object[] Header = new object[ColumnsCount];

                    for (int i = 0; i < ColumnsCount; i++)
                    Header[i] = dtReport.Columns[i].ColumnName;

     Microsoft.Office.Interop.Excel.Range HeaderRange = Worksheet.get_Range((Microsoft.Office.Interop.Excel.Range)(Worksheet.Cells[1, 1]),
     (Microsoft.Office.Interop.Excel.Range)(Worksheet.Cells[1, ColumnsCount]));

                Worksheet.get_Range((Microsoft.Office.Interop.Excel.Range)(Worksheet.Cells[2, 1]), (Microsoft.Office.Interop.Excel.Range)(Worksheet.Cells[RowsCount + 1, ColumnsCount])).Value = Cells;
