问题描述
我使用实体框架4.1 code第一种方法。我能够得到的存储模型类型和列名我的实体:
I'm using the Entity Framework 4.1 with Code First approach. I'm able to get the storage model types and column names of my entities:
var items = context.ObjectContext.MetadataWorkspace.GetItems<EntityType>(DataSpace.SSpace);
foreach (var i in items)
{
Console.WriteLine("Table Name: {0}", i.Name);
Console.WriteLine("Keys:");
foreach (var key in i.KeyMembers)
Console.WriteLine("\t{0} ({1})", key.Name, key.TypeUsage.EdmType.FullName);
Console.WriteLine("Members:");
foreach (var member in i.Members)
Console.WriteLine("\t{0} ({1})", member.Name, member.TypeUsage.EdmType.FullName);
}
我需要的是让实体映射到真正的表名。有不同的方式来指定(通过使用流利的-API .ToTable(),DataAnnotation [TableAttribute])。
What I need is to get the real table name the entity is mapped to. There are different ways to specify that (by using Fluent-API .ToTable(), DataAnnotation [TableAttribute]).
有没有达到这一信息的常用方式?
Is there any common way to achieve this information?
推荐答案
我已经找到了获得表名的最简单方法如下:
The Easiest way I have found to get table names is the following:
var tables = Context.MetadataWorkspace.GetItems(System.Data.Metadata.Edm.DataSpace.CSpace)
.Where(x => (x.MetadataProperties.Contains("NamespaceName") ? String.Compare(x.MetadataProperties["NamespaceName"].Value.ToString(), "Model", true) == 0 : false)
&& !x.MetadataProperties.Contains("IsForeignKey")
&& x.MetadataProperties.Contains("KeyMembers"));
这将让你的表实体。
然后,你可以做以下提取名称:
Then you can do the following to extract the name:
foreach (var item in tables)
{
EntityType itemType = (EntityType)item;
String TableName = itemType.Name;
}
请注意,如果你的复数,你需要撤消的上下文。
Note if your pluralizing the context you will need to undo that.
