删除LINQ to SQL记录而不先加载它

Question

是否有可能让LINQ to SQL使用PK删除记录,而不首先加载记录？类似于NHibernate的代理对象功能？

Answer 1

你应该能够这样做:

var person = new Person();
person.ID = someID;

using (var context = new DataContext(connString))
{
    context.Persons.Attach(person, false); //attach is as unmodified
    context.Persons.DeleteOnSubmit(person); //remove it
    context.SubmitChanges(); //submit changes to db
}
