从EF中的EntityType获取EntitySet名称 [英] Get the EntitySet name from an EntityType in EF

问题描述

给定一个EntityType，例如Contact，如何从其中派生它将属于的EntitySet的名称，即诸如Contacts的复数形式？

解决方案

如果您已经拥有附属实体（显然您不需要第一行，只需使用现有实体）：

 联系c = context.Contacts.Where（x => x.blah）.FirstOrDefault（）; 
 string setName = c.EntityKey.EntitySetName; 
  

或者如果没有：

  string className = typeof（Contact）.Name 
 var container = 
 context.MetadataWorkspace.GetEntityContainer（context.DefaultContainerName，DataSpace.CSpace）; 
 string setName =（from container in container.BaseEntitySets 
 where meta.ElementType.Name == className 
 select meta.Name）.First（）; 
  

Given an EntityType, such as "Contact", how can I derive from it the name of the EntitySet it would belong to, i.e. the pluralization such as "Contacts"?

解决方案

If you already have an attached entity (obviously you don't need the first line, just use your existing entity):

  Contact c = context.Contacts.Where(x => x.blah).FirstOrDefault();
  string setName = c.EntityKey.EntitySetName;

Or if you don't:

 string className = typeof(Contact).Name
 var container =   
    context.MetadataWorkspace.GetEntityContainer(context.DefaultContainerName, DataSpace.CSpace);
    string setName = (from meta in container.BaseEntitySets
                                          where meta.ElementType.Name == className
                                          select meta.Name).First();
