工作之余，把做工程过程中重要的代码段做个记录，如下的资料是关于C#使用Ado.net读取Excel表的代码，应该能对各位有所帮助。

using System;
using System.Data.OleDb;
namespace ConsoleApplication1
{
class Program
{
static void Main()
{
string connString = “Provider=Microsoft.Jet.OleDb.4.0; data source=c:\sample.xls; Extended Properties=Excel 8.0;”;

  OleDbConnection conn = new OleDbConnection(connString);
  OleDbCommand cmd = new OleDbCommand(selectqry,con);

  try
  {
    con.Open();
    OleDbDataReader theDatardr = cmd.ExecuteReader();
    while (theDatardr.Read())
    {
      Console.WriteLine("{0}: {1} ({2}) – {3} ({4})", theDatardr.GetString(0),theDatardr.GetString(1),theDatardr.GetString(2),theDatardr.GetString(3),theDatardr.GetString(4));
    }
  }
  catch (Exception ex)
  {
    Console.WriteLine(ex.Message);
  }
  finally
  {
    con.Dispose();
  }
}

}
}
