using System;
using System.Data;
using System.Data.OleDb;
string ConnectionString = @"Provider=Microsoft.Jet.OleDB.4.0;Data Source=C:\Program Files\Microsoft Office\Office\1033\FPNWIND.mdb";
OleDbConnection conn = new OleDbConnection(ConnectionString);
conn.Open();

   DataTable schemaTable = conn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables,
                                                   new object[] {null, null, null, "TABLE"});
   foreach (DataRow dr in  schemaTable.Rows)
   {
//表名
Console.WriteLine(dr["TABLE_NAME"]);                  //字段名
DataTable columnTable = conn.GetOleDbSchemaTable(OleDbSchemaGuid.Columns,
                new object[] {null, null, dr["TABLE_NAME"].ToString(),null});
             foreach(DataRow dr2 in columnTable.Rows)
             {
                Console.WriteLine("    {0}", dr2["COLUMN_NAME"]);
             } }
conn.Close();
