Entity Framework - Correct way to check for single records before using them

Question

To get a LIST of records I normally do something along the lines of:

var efCompany = from a in _dbRiv.Company where a.CompanyId == companyFeedInfo.CompanyId sele         


        

Answer 1

var efCompany = _dbRiv.Company
                  .SingleOrDefault(a => a.CompanyId == companyFeedInfo.CompanyId);

if (efCompany != null)
{
    // Use it
}
else
{
    // Report to user, or whatever
}
