try this:-
OleDbConnection myConnection = new OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source= D:\\MyDatabase.accdb;Persist Security Info=False;");
myConnection.Open();
OleDbCommand myCommand = new OleDbCommand();
myCommand.Connection = myConnection;
myCommand.CommandText = "CREATE TABLE tblIdentityTesting([MyIdentityColumn] long, [Name] text)";
myCommand.ExecuteNonQuery();
MessageBox.Show("Table Created Successfully");
if you using ms-access 2003 then change
OleDbConnection myConnection = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source= D:\\MyDatabase1.mdb; OLE DB Services=-1");
