不从dataGridView导出列名正确的excel
我试图从dataGridView导出数据到Excel。 它工作正常，但我无法正确导出列名称。 问题是列名应该是： id ，它是idDataGridViewTextBoxColumn 。 而另一个问题是从数据库的第一个条目不导出。 我的意思是，而不是我在数据库中的第一个条目它把列名，然后，它只放第二条目，然后第三，依此类推。 谢谢 ！
private void button3_Click_1(object sender, EventArgs e) { var connString = (@"Data Source=" + Directory.GetParent(Directory.GetCurrentDirectory()).Parent.FullName + @"\Angajati.sdf"); using (var conn = new SqlCeConnection(connString)) { try { conn.Open(); var query = "SELECT * FROM info "; var command = new SqlCeCommand(query, conn); var dataAdapter = new SqlCeDataAdapter(command); var dataTable = new DataTable(); dataAdapter.Fill(dataTable); } catch (Exception ex) { MessageBox.Show(ex.ToString()); } } Excel.Application xlApp; Excel.Workbook xlWorkBook; Excel.Worksheet xlWorkSheet; object misValue = System.Reflection.Missing.Value; Int16 i, j; xlApp = new Excel.Application(); xlWorkBook = xlApp.Workbooks.Add(misValue); xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1); for (i = 0; i <= dataGridView1.RowCount - 2; i++) { for (j = 0; j <= dataGridView1.ColumnCount - 1; j++) { xlWorkSheet.Cells[i + 1, j + 1] = dataGridView1[j, i].Value.ToString(); } } //adds column names to excel string[] colNames = new string[dataGridView1.Columns.Count]; int col = 0; foreach (DataGridViewColumn dc in dataGridView1.Columns) colNames[col++] = dc.Name; char lastColumn = (char)(65 + dataGridView1.Columns.Count - 1); xlWorkSheet.get_Range("A1", lastColumn + "1").Value2 = colNames; xlWorkSheet.get_Range("A1", lastColumn + "1").Font.Bold = true; xlWorkSheet.get_Range("A1", lastColumn + "1").VerticalAlignment = Excel.XlVAlign.xlVAlignCenter; xlWorkBook.SaveAs(@"C:\Users\Andrei\Documents\Visual Studio 2010\Projects\Stellwag\Stellwag\db.xls", Excel.XlFileFormat.xlWorkbookNormal, misValue, misValue, misValue, misValue, Excel.XlSaveAsAccessMode.xlExclusive, misValue, misValue, misValue, misValue, misValue); xlWorkBook.Close(true, misValue, misValue); xlApp.Quit(); releaseObject(xlWorkSheet); releaseObject(xlWorkBook); releaseObject(xlApp); MessageBox.Show("Salvat cu succes"); } private void releaseObject(object obj) { try { System.Runtime.InteropServices.Marshal.ReleaseComObject(obj); obj = null; } catch (Exception ex) { obj = null; MessageBox.Show("Exception Occured while releasing object " + ex.ToString()); } finally { GC.Collect(); } }
对于列名问题，
取代这个：
foreach (DataGridViewColumn dc in dataGridView1.Columns) colNames[col++] = dc.Name;
有了这个：
foreach (DataGridViewColumn dc in dataGridView1.Columns) colNames[col++] = dc.HeaderText;
更新 ：对于第一个缺less的行，进行此更改：
for (i = 0; i <= dataGridView1.RowCount - 2; i++) { for (j = 0; j <= dataGridView1.ColumnCount - 1; j++) { //xlWorkSheet.Cells[i + 1, j + 1] = dataGridView1[j, i].Value.ToString(); xlWorkSheet.Cells[i + 2, j + 1] = dataGridView1[j, i].Value.ToString(); } }
首先，你必须找出问题发生的地方：
- 从GridView获取数据
- 发送数据到excel
使用debuger，设置断点并检查像dataTable和colNames这样的中间值
