这里我使用了Access数据库为例，导入EPPlus如果不会请看上一篇帖子

1.首先先设置EPPlus为非商业使用

  public Homes(){InitializeComponent();ExcelPackage.LicenseContext = OfficeOpenXml.LicenseContext.NonCommercial; // 设置EPPlus为非商业使用} 

2.Access数据库连接方法

 #region Access数据库连接public static DataSet Get(string sql){OleDbConnection oleDb = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + Application.StartupPath + @"\你的根目录下的库名;" + "Jet OLEDB:Database Password = 你的数据库密码");oleDb.Close();DataSet dataSet = new DataSet();DataTable datatable = new DataTable();oleDb.Open();OleDbDataAdapter dbDataAdapter = new OleDbDataAdapter(sql, oleDb);dbDataAdapter.Fill(datatable);dataSet.Tables.Add(datatable);oleDb.Close();return dataSet;}#endregion

3.导入方法

  public static DataTable ReadExcelFile(string filePath){using (var package = new ExcelPackage(new FileInfo(filePath))){ExcelWorksheet worksheet = package.Workbook.Worksheets[0];DataTable table = new DataTable();int columns = worksheet.Dimension.Columns;// 添加表格列for (int col = 1; col <= columns; col++){table.Columns.Add(worksheet.Cells[1, col].Value.ToString());}// 添加数据行for (int row = 2; row <= worksheet.Dimension.Rows; row++){DataRow dataRow = table.NewRow();for (int col = 1; col <= columns; col++){dataRow[col - 1] = worksheet.Cells[row, col].Value;}table.Rows.Add(dataRow);}return table;}}

4.使用导入方法到导入到数据库

  private void button3_Click(object sender, EventArgs e){try{OpenFileDialog openFileDialog = new OpenFileDialog();openFileDialog.Filter = "Excel 文件 (*.xlsx)|*.xlsx|所有文件 (*.*)|*.*";openFileDialog.Title = "选择 Excel 文件";if (openFileDialog.ShowDialog() == DialogResult.OK){string filePath = openFileDialog.FileName;// 构建 SQL 语句DataTable excelData = ReadExcelFile(filePath);foreach (DataRow row in excelData.Rows){//这里{row["姓名"]}是你单元格中对应的每一列的表头Employee.Get($"INSERT INTO workers (Name,Age,Sex,Address,Salary,status) VALUES ('{row["姓名"]}',{row["年龄"]},'{row["性别"]}','{row["住址"]}','{row["薪资"].ToString().Replace("￥", "")}',0);");}}Flushed();//刷新数据NMessage("导入数据成功", NotificationType.Info);}catch (Exception ex){NMessage("导入数据失败"+ex.Message, NotificationType.Error);}}
