一、保存到CSV
public static bool dataGridViewToCSV(DataGridView dataGridView) { if (dataGridView.Rows.Count == 0) { MessageBox.Show("没有数据可导出!", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information); return false; } SaveFileDialog saveFileDialog = new SaveFileDialog(); saveFileDialog.Filter = "CSV files (*.csv)|*.csv"; saveFileDialog.FilterIndex = 0; saveFileDialog.RestoreDirectory = true; saveFileDialog.CreatePrompt = true; saveFileDialog.FileName = null; saveFileDialog.Title = "保存"; if (saveFileDialog.ShowDialog() == DialogResult.OK) { Stream stream = saveFileDialog.OpenFile(); StreamWriter sw = new StreamWriter(stream, System.Text.Encoding.GetEncoding(-0)); string strLine = ""; try { //表头 for (int i = 0; i < dataGridView.ColumnCount; i++) { if (i > 0) strLine += ","; strLine += dataGridView.Columns[i].HeaderText; } strLine.Remove(strLine.Length - 1); sw.WriteLine(strLine); strLine = ""; //表的内容 for (int j = 0; j < dataGridView.Rows.Count; j++) { strLine = ""; int colCount = dataGridView.Columns.Count; for (int k = 0; k < colCount; k++) { if (k > 0 && k < colCount) strLine += ","; if (dataGridView.Rows[j].Cells[k].Value == null) strLine += ""; else { string cell = dataGridView.Rows[j].Cells[k].Value.ToString().Trim(); //防止里面含有特殊符号 cell = cell.Replace("\"", "\"\""); //cell = "\"" + cell + "\""; //每个元素值用引号包括 strLine += cell; } } sw.WriteLine(strLine); } sw.Close(); stream.Close(); MessageBox.Show("数据被导出到：" + saveFileDialog.FileName.ToString(), "导出完毕", MessageBoxButtons.OK, MessageBoxIcon.Information); } catch (Exception ex) { MessageBox.Show(ex.Message, "导出错误", MessageBoxButtons.OK, MessageBoxIcon.Information); return false; } } return true; }二、保存到Excel
public static bool dataGridViewToExcel(DataGridView dataGridView) { if (dataGridView.Rows.Count == 0) { MessageBox.Show("没有数据可导出!", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information); return false; } string fileName = ""; string saveFileName = ""; SaveFileDialog saveDialog = new SaveFileDialog(); saveDialog.DefaultExt = "xlsx"; saveDialog.Filter = "Excel文件|*.xlsx"; saveDialog.FileName = fileName; saveDialog.ShowDialog(); saveFileName = saveDialog.FileName; if (saveFileName.IndexOf(":") < 0) return false; //被点了取消 Microsoft.Office.Interop.Excel.Application xlApp = new Microsoft.Office.Interop.Excel.Application(); if (xlApp == null) { MessageBox.Show("无法创建Excel对象，您的电脑可能未安装Excel"); return false; } Microsoft.Office.Interop.Excel.Workbooks workbooks = xlApp.Workbooks; Microsoft.Office.Interop.Excel.Workbook workbook = workbooks.Add(Microsoft.Office.Interop.Excel.XlWBATemplate.xlWBATWorksheet); Microsoft.Office.Interop.Excel.Worksheet worksheet = (Microsoft.Office.Interop.Excel.Worksheet)workbook.Worksheets[1];//取得sheet1 //写入标题 for (int i = 0; i < dataGridView.ColumnCount; i++) { worksheet.Cells[1, i + 1] = dataGridView.Columns[i].HeaderText; } //写入数值 for (int r = 0; r < dataGridView.Rows.Count; r++) { for (int i = 0; i < dataGridView.ColumnCount; i++) { worksheet.Cells[r + 2, i + 1] = dataGridView.Rows[r].Cells[i].Value; } System.Windows.Forms.Application.DoEvents(); } worksheet.Columns.EntireColumn.AutoFit();//列宽自适应 MessageBox.Show(fileName + "资料保存成功", "提示", MessageBoxButtons.OK); if (saveFileName != "") { try { workbook.Saved = true; workbook.SaveCopyAs(saveFileName); //fileSaved = true; } catch (Exception ex) {//fileSaved = false; MessageBox.Show("导出文件时出错,文件可能正被打开！\n" + ex.Message); } } xlApp.Quit(); Kill(xlApp); GC.Collect();//强行销毁 return true; }到此，关于“C#怎么将DataGridView中的数据保存到CSV和Excel中”的学习就结束了，希望能够解决大家的疑惑。理论与实践的搭配能更好的帮助大家学习，快去试试吧！若想继续学习更多相关知识，请继续关注编程网网站，小编会继续努力为大家带来更多实用的文章！
