C#中ExcelDataReader的具体使用

using System.Text;
using ExcelDataReader;

public class Program
{
    static void Main(string[] args)
    {
        Encoding.RegisterProvider(CodePagesEncodingProvider.Instance);

        string filePath = "Excel.xlsx";
        using (FileStream stream = File.OpenRead(filePath))
        {
            using (IExcelDataReader reader = ExcelReaderFactory.CreateReader(stream))
            {
                // 1. Use the reader methods
                do
                {
                    Console.WriteLine($"Sheet name:{reader.Name}");

                    while (reader.Read())
                    {
                        Console.WriteLine($"{reader.GetString(0)} \t\t{reader.GetString(1)}");
                    }

                    Console.WriteLine();
                } while (reader.NextResult());
            }
        }
    }
}

using System.Data;
using System.Text;
using ExcelDataReader;

public class Program

            {
                // 2. Use the AsDataSet extension method
                DataSet dataSet = reader.AsDataSet();

                DataTable dataTable = dataSet.Tables[0];
                Console.WriteLine(dataTable.TableName);

                    Console.WriteLine();
                }
