C#对DBF文件的操作

 protected void Page_Load(object sender, EventArgs e)
     {
         System.Data.Odbc.OdbcConnection conn = new System.Data.Odbc.OdbcConnection();
         string table = @"D:\aaa\code.dbf";
         string connStr=@"Driver={Microsoft Visual FoxPro Driver};SourceType=DBF;SourceDB=" + table + ";Exclusive=No;NULL=NO;Collate=Machine;BACKGROUNDFETCH=NO;DELETED=NO";  

         conn.ConnectionString = connStr;
         conn.Open();  

         OdbcCommand cmd = new OdbcCommand();
         cmd.Connection = conn;
         string sql = "update " + table + " set other='2',rate=1.014 ";
         cmd.CommandText = sql;
         cmd.CommandType = CommandType.Text;
         cmd.ExecuteNonQuery();  

          sql = @"select * from " + table;
         OdbcDataAdapter da = new OdbcDataAdapter(sql,conn);
         DataTable dt = new DataTable();
         da.Fill(dt);
         this.GridView1.DataSource = dt.DefaultView;
         this.GridView1.DataBind();
     }  

 注意点： 连接串的格式。 所对应的表名必须要有路径
