i am getting this error " System.Data.C开发者_开发技巧ommon.DataAdapter.DataAdapter()' is inaccessible due to its protection level"

You can't. The constructor is protected because this class is not intended to be instantiated by user code. You could use the specific adapter for your database. For example for SQL Server that would be: SqlDataAdapter.
