如何将数据库中的数据导入excel表单？

我想从数据库生成一个Excel表（SQL 2008）。 我写下面提到的代码，但它不工作。 请帮我改进我的代码。 在我的示例代码下面

protected void generate_Click(object sender, EventArgs e) { DataTable dt = new DataTable(); //My Function which generates DataTable DataSet ds = new DataSet(); using (ExcelPackage p = new ExcelPackage()) { //Here setting some document properties p.Workbook.Properties.Author = "Zeeshan Umar"; p.Workbook.Properties.Title = "Office Open XML Sample"; //Create a sheet p.Workbook.Worksheets.Add("Sample WorkSheet"); ExcelWorksheet ws = p.Workbook.Worksheets[1]; ws.Name = "Sample Worksheet"; //Setting Sheet's name ws.Cells.Style.Font.Size = 11; //Default font size for whole sheet ws.Cells.Style.Font.Name = "Calibri"; //Default Font name for whole sheet //Merging cells and create a center heading for out table ws.Cells[1, 1].Value = "msd"; ws.Cells[1, 1, 1, ws.Dimension.End.Column].Merge = true; // ws.Cells[1, 1, 1, dt.Columns.Count].Merge = true; ws.Cells[1, 1, 1, ws.Dimension.End.Column].Style.Font.Bold = true; ws.Cells[1, 1, 1, ws.Dimension.End.Column].Style.HorizontalAlignment = ExcelHorizontalAlignment.Center; int colIndex = 1; int rowIndex = 2; SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["ApplicationServices"].ConnectionString); SqlCommand cmd = new SqlCommand("SELECT Fname,Mname FROM EmpMaster where EmpCode='" + ddcode.SelectedItem.Text + "'", conn); // dr = conn.query(str); SqlDataAdapter adr = new SqlDataAdapter(); adr.SelectCommand = cmd; adr.Fill(dt); //Add the table to the data set ds.Tables.Add(dt); //cell.Value = "Heading " + ds.ColumnName; var rows = ds.Tables[0].Rows; foreach (DataRow row in rows) { string name = Convert.ToString(row["Fname"]); string code = Convert.ToString(row["Mname"]); string lname = Convert.ToString(row["Lname"]); //ws.Cells[colIndex +1 , rowIndex +0].Value = name; //ws.Cells[colIndex +1, rowIndex +1].Value = code; //ws.Cells[colIndex +1, rowIndex +2].Value = lname; ws.Cells[rowIndex , colIndex ].Value = name; ws.Cells[rowIndex , colIndex +1 ].Value = code; ws.Cells[rowIndex , colIndex +2].Value = lname; // Move to the next row in the sheet. rowIndex++; colIndex++; } //Generate A File with Random name Byte[] bin = p.GetAsByteArray(); string file = "F:\\ excelsample.xlsx"; File.WriteAllBytes(file, bin); System.Diagnostics.Process.Start("F:\\ excelsample.xlsx"); } } 

这将生成Excel表，但它只显示一行（中间名）。 我有两个值名字和中间名。 我怎么能实现它？

 foreach (DataRow row in rows) { string name = Convert.ToString(row["Fname"]); string code = Convert.ToString(row["Middle Name"]); // Setting Value in cell ws.Cells[colIndex, rowIndex].Value = name; ws.Cells[colIndex + 1, rowIndex].Value = code; // Move to the next row in the sheet. rowIndex++; }
