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(); } } }}
