如何把一个dataset中的多张table导入到excel里的不同sheets

[owl1986]

请问如何把一个dataset中的多张table导入到excel里的不同sheets呢.每张表对应一个相应的sheet

[ysudongxi]

dataset.Tables[i].Rows[][]不同table单元格的内容依次写到excel的不同sheet中。
你可以搜搜如何往excel中导入数据。再按这个试试。

excel中sheet的名字是固定的,要把对应的table导进去...

Microsoft.Office.Interop.Excel.Application app =
                    new Microsoft.Office.Interop.Excel.ApplicationClass();
                Object missing = System.Reflection.Missing.Value;
                Microsoft.Office.Interop.Excel.Workbooks m_objWorkBooks = app.Workbooks;
                Microsoft.Office.Interop.Excel.Workbook m_objWorkBook = m_objWorkBooks.Add(true);
                //Microsoft.Office.Interop.Excel.Sheets m_objWorkSheets = m_objWorkBook.Sheets;                
                m_objWorkBook = app.Workbooks.Open(sourcefilePath, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing);
                Microsoft.Office.Interop.Excel.Worksheet m_objWorkSheet = (Microsoft.Office.Interop.Excel.Worksheet)m_objWorkBook.Sheets[1];
                try
                {
                    app.Visible = false;                  
                    if (excelTable.Rows.Count > 0)
                    {
                        int row = 0;
                        row = excelTable.Rows.Count;
                        int col = excelTable.Columns.Count;
                        for (int i = 0; i < row; i++)
                        {
                            for (int j = 0; j < col; j++)
                            {
                                string str = excelTable.Rows[i][j].ToString();
                                m_objWorkSheet.Cells[i + 3, j + 1] = str;
                            }
                        }
                    }
// 设置禁止弹出保存和覆盖的询问提示框    
                    app.DisplayAlerts = false;
                    app.AlertBeforeOverwriting = false;
                    //保存excel文件    
                    m_objWorkSheet.SaveAs(sourcefilePath, missing, missing, missing, missing, missing, missing, missing, missing, missing);
                    //app.PrintPreview(); 
                    app.Quit();
                    app = null;

不同sheet设定活动状态Microsoft.Office.Interop.Excel.Worksheet m_objWorkSheet = (Microsoft.Office.Interop.Excel.Worksheet)m_objWorkBook.Sheets[1];
sheet[1],sheet[2]..
