這期內(nèi)容當(dāng)中小編將會(huì)給大家?guī)?lái)有關(guān)C#如何將DataGridView中的數(shù)據(jù)導(dǎo)入到Csv文件及導(dǎo)出到Excel,文章內(nèi)容豐富且以專(zhuān)業(yè)的角度為大家分析和敘述,閱讀完這篇文章希望大家可以有所收獲。
10年的金門(mén)網(wǎng)站建設(shè)經(jīng)驗(yàn),針對(duì)設(shè)計(jì)、前端、開(kāi)發(fā)、售后、文案、推廣等六對(duì)一服務(wù),響應(yīng)快,48小時(shí)及時(shí)工作處理。營(yíng)銷(xiāo)型網(wǎng)站的優(yōu)勢(shì)是能夠根據(jù)用戶設(shè)備顯示端的尺寸不同,自動(dòng)調(diào)整金門(mén)建站的顯示方式,使網(wǎng)站能夠適用不同顯示終端,在瀏覽器中調(diào)整網(wǎng)站的寬度,無(wú)論在任何一種瀏覽器上瀏覽網(wǎng)站,都能展現(xiàn)優(yōu)雅布局與設(shè)計(jì),從而大程度地提升瀏覽體驗(yàn)。創(chuàng)新互聯(lián)建站從事“金門(mén)網(wǎng)站設(shè)計(jì)”,“金門(mén)網(wǎng)站推廣”以來(lái),每個(gè)客戶項(xiàng)目都認(rèn)真落實(shí)執(zhí)行。
1,將DataGridView中的數(shù)據(jù)導(dǎo)入到Csv文件中
public static bool dataGridViewToCSV(DataGridView dataGridView) { if (dataGridView.Rows.Count == 0) { MessageBox.Show("沒(méi)有數(shù)據(jù)可導(dǎo)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 { //表頭 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 = ""; //表的內(nèi)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號(hào) cell = cell.Replace("\"", "\"\""); cell = "\"" + cell + "\""; strLine += cell; } } sw.WriteLine(strLine); } sw.Close(); stream.Close(); MessageBox.Show("數(shù)據(jù)被導(dǎo)出到:" + saveFileDialog.FileName.ToString(), "導(dǎo)出完畢", MessageBoxButtons.OK, MessageBoxIcon.Information); } catch (Exception ex) { MessageBox.Show(ex.Message, "導(dǎo)出錯(cuò)誤", MessageBoxButtons.OK, MessageBoxIcon.Information); return false; } } return true; }
2,C#中將DataGridView中的數(shù)據(jù)導(dǎo)出到Excel中
public static bool dataGridViewToExcel(DataGridView dataGridView) { if (dataGridView.Rows.Count == 0) { MessageBox.Show("沒(méi)有數(shù)據(jù)可導(dǎo)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; //被點(diǎn)了取消 Microsoft.Office.Interop.Excel.Application xlApp = new Microsoft.Office.Interop.Excel.Application(); if (xlApp == null) { MessageBox.Show("無(wú)法創(chuàng)建Excel對(duì)象,您的電腦可能未安裝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 //寫(xiě)入標(biāo)題 for (int i = 0; i < dataGridView.ColumnCount; i++) { worksheet.Cells[1, i + 1] = dataGridView.Columns[i].HeaderText; } //寫(xiě)入數(shù)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();//列寬自適應(yīng) MessageBox.Show(fileName + "資料保存成功", "提示", MessageBoxButtons.OK); if (saveFileName != "") { try { workbook.Saved = true; workbook.SaveCopyAs(saveFileName); //fileSaved = true; } catch (Exception ex) {//fileSaved = false; MessageBox.Show("導(dǎo)出文件時(shí)出錯(cuò),文件可能正被打開(kāi)!\n" + ex.Message); } } xlApp.Quit(); Kill(xlApp); GC.Collect();//強(qiáng)行銷(xiāo)毀 return true; }
//*********************************************************************************************// //*功能:當(dāng)使用Excel.Application方法的時(shí)候,系統(tǒng)會(huì)自動(dòng)創(chuàng)建一個(gè)Excel進(jìn)程,即使當(dāng)你使用Excel.Quit()之后,也是不會(huì)關(guān)閉的。 //*參數(shù):通過(guò)進(jìn)程ID來(lái)唯一標(biāo)識(shí)我們自己創(chuàng)建的進(jìn)程,然后在關(guān)閉Excel.Application的時(shí)候一同將進(jìn)程Kill掉。 //*返回值:無(wú) //*時(shí)間:2018-04-25 //**********************************************************************************************// public static void Kill(Microsoft.Office.Interop.Excel.Application excel) { IntPtr t = new IntPtr(excel.Hwnd); int k = 0; GetWindowThreadProcessId(t, out k); System.Diagnostics.Process p = System.Diagnostics.Process.GetProcessById(k); p.Kill(); }
