好的，我正在尝试找出在代码中实现此目的的最佳方法。我有一个包含大量选项卡的电子表格，我想要做的是在C＃中读取每个工作表的名称，然后读取相应的数据行。目前，这就是我所拥有的：

            if (!DirectoryIsEmpty(DropZone.ToString())) 
        { 

            DirectoryInfo di = new DirectoryInfo(DropZone); 
            FileInfo[] fi = di.GetFiles(); 
            // step through each found file 
            foreach (FileInfo fiTemp in fi) 
            { 
                //    Connection String to Excel Workbook 
                string excelConnStr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source='" + DropZone + "\\" + fiTemp + "'; Extended Properties=\"Excel 8.0; HDR=YES; IMEX=1;\""; 
                string SheetName = string.Empty; 
                //    Create Connection to Excel Workbook 
                using (OleDbConnection connection = new OleDbConnection(excelConnStr)) 
                { 
                    try 
                    { 
                        string curaddy2 = string.Empty; 
                        string priaddy2 = string.Empty; 
                        connection.Open(); 
                        DataTable dt = connection.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null); 
                        if (dt != null) 
                        { 
                            string[] excelSheets = new String[dt.Rows.Count]; 
                            int i = 0; 
                            foreach (DataRow row in dt.Rows) 
                            { 
                                excelSheets[i] = row["TABLE_NAME"].ToString();                                     
                                #region ExcelReading 
                                SheetName = excelSheets[i].ToString(); 
                                OleDbCommand command = new OleDbCommand("SELECT [Name], [Address], [City], [State], [Zip] FROM '" + SheetName.ToString() + "'", connection); 
                                using (DbDataReader dr = command.ExecuteReader()) 
                                { 
                                    // SQL Server Connection String 

                                    string sqlConnectionString = DBUtils.DBString; 
                                    // Bulk Copy to SQL Server 
                                    using (SqlBulkCopy bulkCopy = new SqlBulkCopy(sqlConnectionString)) 
                                    { 
                    // Columns get copied from sheet and into bulk copy statement 
                                        logger.MyLogFile("" + DateTime.Now.ToString() + " Bulk Copy: ", "ID Number " + dr.GetValue(0).ToString() + ""); 
                                        // now that matrix is created, do the insert 
                                        bulkCopy.DestinationTableName = "Table"; 
                                        bulkCopy.WriteToServer(dr); 
                                        logger.MyLogFile("" + DateTime.Now.ToString() + " Bulk Copy: ", "All values inserted as burst"); 
                                    } 
                                } 
                                #endregion 
                                i++; 
                            } 
                        } 
                        dt.Dispose(); 
                    } 
                    catch (Exception ex) 
                    { 
                        logger.MyLogFile("" + DateTime.Now.ToString() + " Importer \n", "Import failed, error code: " + ex.ToString() + ""); 
                    }                         
                    finally 
                    {                             
                        connection.Close(); 
                    } 
                } 
            }

excelSheets的名称是$吗？如果没有尝试更改：OleDbCommand command = new OleDbCommand("SELECT [Name], [Address], [City], [State], [Zip] FROM '" + SheetName.ToString() + "'", connection); 到：

OleDbCommand command = new OleDbCommand("SELECT [Name], [Address], [City], [State], [Zip] FROM [" + SheetName.ToString() + "$]", connection);

由于某些原因，电子表格名称与$连接在一起。我不久前被困在了这个位置，它帮助了我。

获取电子表格名称，然后在Foreach中读取每个名称
