C# 实体框架,提供程序无法打开
我得到了这个错误:C# 实体框架,提供程序无法打开,c#,entity-framework,connection-string,C#,Entity Framework,Connection String,我得到了这个错误: -InnerException {"Connection Timeout Expired.

-InnerException {"Connection Timeout Expired. The timeout period elapsed during the post-login phase. The connection could have timed out while waiting for server to complete the login process and respond; Or it could have timed out while attempting to create multiple active connections. The duration spent while attempting to connect to this server was - [Pre-Login] initialization=86; handshake=2368; [Login] initialization=0; authentication=0; [Post-Login] complete=12018; "} System.Exception {System.Data.SqlClient.SqlException}
由此:
DataSourceContext Context = new DataSourceContext();
var Booklist = Context.Booklists.ToList();
Context.Dispose();
Parallel.ForEach(Booklist, currentBook =>
{
switch (currentBook.FKcatalogNum)
{
case 0:
{
...
finally
{
currentBook.BookDetails = Models.DBBookSourceInitializer.GetBookReaderNet(currentBook.Link);
try
{
context.Booklists.AddOrUpdate(currentBook);
context.SaveChanges();
}
catch (Exception e)
{
...
context.Booklists.AddOrUpdate(currentBook);
context.SaveChanges();
}
context.Dispose();
}
break;
我试图从数据库中获取所有书名,并添加有关其摘要、章节、页数等的详细信息。但我不断收到连接错误。有数千本书,在处理了一定数量的内容后,它给了我这个错误。从最后一本书的主键判断,它是1180,这意味着1180本书很好,然后突然发生了这种情况。
有人能告诉我我做错了什么,或者我应该改变什么吗。
谢谢你的帮助 你为什么要在使用前处理上下文?我没有?“…”表示我使用的一些代码,在我处理它之前,我正在try-catch块中使用它们?用一段短得多的代码复制这个错误,然后发布那个错误,而不是长版本。
