Is it necessary to destroy the class instances in my loop?

Suppose I have a loop which creates a new instance of a EF Class to add to databasde table in each loop iteration:

foreach (var record in records)
{
    InvestmentTransactionStaging newRecord = new()
    {
        UserId = UserId,
        InvestmentTransactionTypeId = interestRepaymentTransactionTypeId,
        InvestmentEntityId = InvestmentEntityId,
        Description = record.LoanReference,
        Date = DateTime.Parse(record.Date),
    };
    _context.InvestmentTransactionsStaging.Add(newRecord);
}

Now normally, in the languages I am used to such as php it is not important destroy the instance after the call to _context..Add(), the garbage Collector takes care of it. If I omit this as I have above, would this then potentially cause any issues with memory in C#? Do I need to destroy the instance on each itertation that it is instamtiated and if so how? (I could not use the Disapose method as it complains the method is unavailable.

>Solution :

Created objects are automatically destructed when no longer reachable

Meaning, any object created, lives only as long as the running code is still between curly braces, where it was instantiated
