删除 LINQ to SQL 记录而不先加载它

Delete a LINQ to SQL record without loading it first(删除 LINQ to SQL 记录而不先加载它)

问题描述

是否可以让 LINQ to SQL 使用 PK 删除记录，而无需先加载记录?类似于NHibernate的代理对象功能?

Is it possible to get LINQ to SQL to delete a record using the PK, without loading the record first? Similar to NHibernate's proxy object functionality?

推荐答案

你应该可以这样做:

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
}
