使用c＃在单个xlsx中读取多个Excel工作表

我试图开发一段代码，将抓取单个xlsx中的3个工作表的数据，并将其上传到SQL Server上的3个不同的表。 每个工作表应该上传其内容到一个表（工作表1上传到表客户，工作表2上传到表销售，…）

我设法把它从工作表1的所有数据上传到一个表…这里是它的代码：

public partial class LoggedHome : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { if (IsPostBack && Upload.HasFile) { if (Path.GetExtension(Upload.FileName).Equals(".xlsx")) { var excel = new ExcelPackage(Upload.FileContent); var dt = excel.ToDataTable(); var table = "MenuPrice"; using (var conn = new SqlConnection("Removed for security purpouses")) { var bulkCopy = new SqlBulkCopy(conn); bulkCopy.DestinationTableName = table; conn.Open(); var schema = conn.GetSchema("Columns", new[] { null, null, table, null }); foreach (DataColumn sourceColumn in dt.Columns) { foreach (DataRow row in schema.Rows) { if (string.Equals(sourceColumn.ColumnName, (string)row["COLUMN_NAME"], StringComparison.OrdinalIgnoreCase)) { bulkCopy.ColumnMappings.Add(sourceColumn.ColumnName, (string)row["COLUMN_NAME"]); break; } } } bulkCopy.WriteToServer(dt); } } else { ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "alertMessage", "alert('This is not an Excel file. Please upload a proper file.')", true); } } } } public static class ExcelPackageExtensions { public static DataTable ToDataTable(this ExcelPackage package) { ExcelWorksheet workSheet = package.Workbook.Worksheets.First(); DataTable table = new DataTable(); foreach (var firstRowCell in workSheet.Cells[1, 1, 1, workSheet.Dimension.End.Column]) { table.Columns.Add(firstRowCell.Text); } for (var rowNumber = 2; rowNumber <= workSheet.Dimension.End.Row; rowNumber++) { var row = workSheet.Cells[rowNumber, 1, rowNumber, workSheet.Dimension.End.Column]; var newRow = table.NewRow(); foreach (var cell in row) { newRow[cell.Start.Column - 1] = cell.Text; } table.Rows.Add(newRow); } return table; } } 

任何帮助深表感谢！ 谢谢

这行只是检索第一个工作表

 ExcelWorksheet workSheet = package.Workbook.Worksheets.First(); 

将其更改为for循环，就像您对单元格和行所做的那样

 DataTable table = new DataTable(); foreach (var workSheet in package.Workbook.Worksheets) { // Existing code } return table;
