我知道，这就是我最近在这里发布的内容（现已更正）。由于使用后未放置
ExcelPackage和和
FileStream（从
File.OpenRead），因此可以进行改进。
public static DataTable GetDataTableFromExcel(string path, bool hasHeader = true){ using (var pck = new OfficeOpenXml.ExcelPackage()) { using (var stream = File.OpenRead(path)) { pck.Load(stream); } var ws = pck.Workbook.Worksheets.First(); DataTable tbl = new DataTable(); foreach (var firstRowCell in ws.Cells[1, 1, 1, ws.Dimension.End.Column]) { tbl.Columns.Add(hasHeader ? firstRowCell.Text : string.Format("Column {0}", firstRowCell.Start.Column)); } var startRow = hasHeader ? 2 : 1; for (int rowNum = startRow; rowNum <= ws.Dimension.End.Row; rowNum++) { var wsRow = ws.Cells[rowNum, 1, rowNum, ws.Dimension.End.Column]; DataRow row = tbl.Rows.Add(); foreach (var cell in wsRow) { row[cell.Start.Column - 1] = cell.Text; } } return tbl; }}
