我试图根据情况重述背景的变化。 重新计算法 似乎Refresh不是背景的成员。
I m 采用Microsoft ADO。 NET 实体框架4.1 驻地协调员版本。
任何想法?

/a>,其中没有Refresh
方法。 您可使用IObjectContextAdapter接口,以获取以下编码:ObjectContext,并打电话Refresh。
var objectContext = ((IObjectContextAdapter)context).ObjectContext;
您也可使用代氧物体上的重载功能...... 此处为重载所有改装物体的样本:
var modifiedEntries = context.ChangeTracker.Entries()
.Where(e => e.State == EntityState.Modified);
foreach (var modifiedEntry in modifiedEntries) {
modifiedEntry.Reload();
}
www.un.org/Depts/DGACM/index_spanish.htm 在座标上张贴的答案也可能是:。 Refresh entities instance with DbContext
简言之,您可尝试提出如下内容:
dbContext.Entry(someEntityObjectInstance).Reload();
然而,其他人指出,这确实是新的导航性能,因此,如果你不得不担心更新导航性能,你要么需要重载所有导航特性,要么需要抛弃()或重新添加(......),然后再投向国际宇宙航行局,或者可能只是重修你的DbContext。
就我而言,我坦率地决定,最好重新审视一下情况,重新确定实体:
dbContext = new Model.Entities();
someEntityObjectInstance = dbContext.SomeEntityType.Find(someEntityObjectInstanceKey);
这里也许没有简单/最简单的答案。
