几天前,我遇到了EF中一个最着名的问题,即批量插入.经过一些谷歌搜索我发现：
http://efbulkinsert.codeplex.com/
在使用复杂的数据模型失败后,我回到了一个简单的测试人员.
我正在尝试插入的实体如下所示：
Id – Int
名称 – 字符串
使用VS生成实体,然后使用VS内置功能跟踪数据库.
我尝试了两个EF,4和5.没有工作.例外是：
空间’Csspace’没有相关的集合.
两种数据模型的例外情况相同.
据我所知,我使用了所有依赖项.
代码：
using (Model1Container ctx = new Model1Container())
{
List<TestEntity> list = new List<TestEntity>();
for (int i = 0; i < 10; i++)
{
TestEntity enti = ctx.TestEntitySet.Create();
enti.Name = "stav" + i;
list.Add(enti);
ctx.TestEntitySet.Add(enti);
}
ctx.BulkInsert<TestEntity>(list);
}
stacktrace是这样的：

有任何想法吗？
