推荐答案

通常您不能这样做-您必须循环执行。但是，在某些情况下，可以避免添加每个对象-特别是如果您有实体图并添加父节点。例如。如果您有一个 Company 对象，该对象具有 Employees 的集合：

Generally you can't do that - you have to do it in a loop. In some cases, however, you can avoid adding every object - specifically, if you have an entity graph and you add the parent node. E.g. if you have a Company object that has a collection of Employees:

context.AddToCompanies(company);

/* The following loop is not necessary */
/* The employees will be saved together with the company */
/*
foreach (var employee in company.Employees)
{
    context.AddToEmployees(employee);
}*/

context.SaveChanges();
