nested sell linq sql

i need assistance realizing definitely challenging business explanation operates tables executes definitely few sql commands. however i wish certain information left incosistent state impulse i don't fortitude need nested transactions. i wrote rudimentary pseudo-code illustrates unfolding identical i wish accomplish:

dictionary<int, bool> opsucceeded = new dictionary<int, bool> ();

for (int i = 0; i < 10; i++)
{
    try
    {   
        // operation contingency atomic
        operation(dbcontext, i);

        // dedicate (?)

        opsucceeded[i] = true;
    }
    catch
    {
        // ignore
    }
}

try
{
    // operation contingency know operation(i) succeeded;
    // also contingency atomic
    finaloperation(dbcontext, opsucceeded);

    // dedicate all
}
catch
{
    // rollback finaloperation operation(i) where opsucceeded[i] == true
}

the biggest problem me is: pledge finaloperation fails, operations operation(i) succeeded rolled back? note i also means replace failures unparalleled operation(i).

is illusory grasp controlling nested transactionscope objects - proceed such problem?
