使用oledb网的多页导入”_xlnm#_过滤器数据库”；作为图纸名称

我有一个包含多个工作表的excel，我想导入它
代码相当简单和基本，应该可以工作
但我的表单在调试器中一直以"_xlnm#_FilterDatabase"的形式返回
是我问题的根源

这是代码的相关部分：

        string sheetName = "";
        file = HostingEnvironment.MapPath("~/files/master1.xlsx");
        xConnStr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + file + ";Extended Properties='"Excel 12.0 Xml;HDR=YES;IMEX=1'";";
        using (OleDbConnection connection = new OleDbConnection(xConnStr))
        {
            // get sheet names
            connection.Open();
            DataTable sheets = connection.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
            // eeo10 (2nd tab: first sheet to be imported)
            sheetName = sheets.Rows[1]["TABLE_NAME"].ToString();
            OleDbCommand command = new OleDbCommand("Select * FROM ["+sheetName+"]", connection);
            // Create DbDataReader to Data Worksheet                
            using (OleDbDataReader dr = command.ExecuteReader())
            {
                // Bulk Copy to SQL Server
                using (SqlBulkCopy bulkCopy = new SqlBulkCopy(sqlConnx))
                {
                    bulkCopy.ColumnMappings.Add("code", "id");
                    bulkCopy.ColumnMappings.Add("category10", "category");
                    bulkCopy.DestinationTableName = "eeo10";
                    bulkCopy.WriteToServer(dr);
                }
            }
            // eeo14 (3rd tab: second sheet to be imported)
            sheetName = sheets.Rows[2]["TABLE_NAME"].ToString();
            command = new OleDbCommand("Select * FROM [" + sheetName + "]", connection);
            DataTable cols = connection.GetOleDbSchemaTable(OleDbSchemaGuid.Columns, new object[] { null, null, sheetName, null });
            foreach (DataRow r in cols.Rows)
            {
                System.Diagnostics.Debug.WriteLine("{0} = {1}", r["COLUMN_NAME"], r["ORDINAL_POSITION"]);
            }
            // Create DbDataReader to Data Worksheet                
            using (OleDbDataReader dr = command.ExecuteReader())
            {
                // Bulk Copy to SQL Server
                using (SqlBulkCopy bulkCopy = new SqlBulkCopy(sqlConnx))
                {
                    bulkCopy.ColumnMappings.Add("code", "id");
                    bulkCopy.ColumnMappings.Add("category14", "category");
                    bulkCopy.DestinationTableName = "eeo14";
                    bulkCopy.WriteToServer(dr);
                }
            }
        }

如前所述
调试器返回sheetName="_xlnm#_FilterDatabase"
奇怪的是，eeo10的第一个工作原理
但eeo14没有，因为它仍在尝试使用eeo10表

以下可能是其他一些相关信息：
-我已关闭工作簿中的自动筛选
-我把列标题打印出来只是为了确认它在读

任何见解都很有价值
非常感谢！

class Retriever
{
    public List<SheetName> GetSheetNames(OleDbConnection conn)
    {
        List<SheetName> sheetNames = new List<SheetName>();
        if (conn.State != ConnectionState.Open)
        {
            conn.Open();
        }
        DataTable excelSchema = conn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
        foreach (DataRow row in excelSchema.Rows)
        {
            if (!row["TABLE_NAME"].ToString().Contains("FilterDatabase"))
            {
               sheetNames.Add(new SheetName() { sheetName = row["TABLE_NAME"].ToString(), sheetType = row["TABLE_TYPE"].ToString(), sheetCatalog = row["TABLE_CATALOG"].ToString(), sheetSchema = row["TABLE_SCHEMA"].ToString() });
            }
        }
        conn.Close();
        return sheetNames;
     }
