用C读取Excel文件-选择工作表

有关如何按顺序获取工作表名称列表,请参见此答案: Using Excel OleDb to get sheet names IN SHEET ORDER

这是我的版本,稍微短一点:

public static IEnumerable<string> GetExcelSheetNames(string excelFile)
{
    var connectionString = "Provider=Microsoft.Jet.OLEDB.4.0;" +
          "Data Source=" + excelFile + ";Extended Properties=Excel 8.0;";
    using (var connection = new OleDbConnection(connectionString))
    {
        connection.Open();
        using (var dt = connection.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null))
        {
            return (dt ?? new DataTable())
                .Rows
                .Cast<DataRow>()
                .Select(row => row["TABLE_NAME"].ToString());
        }
    }
}
