如何使用 OLEDB 按原始顺序检索 Excel 工作表名称？

private String[] GetExcelSheetNames(string excelFile)
{
    // Establish connection parameters
    string connString = "Provider=Microsoft.Jet.OLEDB.4.0;" +
        "Data Source=" + excelFile + ";Extended Properties=Excel 8.0;";

    // Create connection and database linkage
    using (OleDbConnection objConn = new OleDbConnection(connString))
    {
        objConn.Open();

        // Retrieve schema table
        DataTable dt = objConn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);

        // Initialize array for sheet names
        String[] excelSheets = new String[dt.Rows.Count];

        // Populate array with sequential sheet names
        int index = 0;
        foreach (DataRow row in dt.Rows)
        {
            excelSheets[index++] = row["TABLE_NAME"].ToString();
        }

        return excelSheets;
    }
}
