C# 未从dataGridView将列名正确导出到excel

我正在尝试将数据从dataGridView导出到excel。它工作正常，但我无法正确导出列名。问题是列名应该是：id，它是idDataGridViewTextBoxColumn。另一个问题是数据库中的第一个条目没有导出。我的意思是，它不放我在db中的第一个条目，而是放列名，然后，它只放第二个条目，然后是第三个条目，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();
            }
        }

首先，您必须找出问题发生的位置：

从GridView获取数据 将数据发送到excel

---

使用调试程序，设置断点并检查列名问题的中间值，如dataTable和colNames

替换此项：

foreach (DataGridViewColumn dc in dataGridView1.Columns)
    colNames[col++] = dc.Name;

为此：

foreach (DataGridViewColumn dc in dataGridView1.Columns)
    colNames[col++] = dc.HeaderText;

更新：对于缺少的第一行，进行以下更改：

        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();
            }
        }

这样很有魅力。剩下的唯一问题是它没有得到数据库中的第一个条目，只有第二个条目，因为第一个条目被替换为列名。为什么？
