获取Access用户定义的表名和各表的字段名

 public   static  DataTable GetSchemaTable(string connectionString)  //获取Access所有的表名；
        {
            using (OleDbConnection connection = new
                       OleDbConnection(connectionString))
            {
                connection.Open();
                DataTable schemaTable = connection.GetOleDbSchemaTable(
                    OleDbSchemaGuid.Tables,
                    new object[] { null, null, null, "TABLE" });
                return schemaTable;
            }
        }
 private string[] GetTabelName(string conn)  //获取Access文件中所有表名，放在数组里面
        {
            DataTable dt = GetSchemaTable(conn);
            int n = dt.Rows.Count;
            string[] strTable = new string[n];
            int m = dt.Columns.IndexOf("TABLE_NAME");
            for (int i = 0; i < n; i++)
