SQL SERVER2005連接字串中的@3/29

下載了祭司的Client-CallBack參考程式碼,在連接SQL SERVER2005時,將其中的

SqlConnection conn = new SqlConnection("data source=.;initial catalog=Northwind;user id=sa;password=test");

改為

SqlConnection conn = new SqlConnection("Data Source=DAISYLH/SQLEXPRESS;Initial Catalog=Northwind;Integrated Security=True;Pooling=False");

時在DAISYLH/S處出現:無法辨認的溢出序列

若將DAISYLH/去掉,則出現:

An error has occurred while establishing a connection to the server.
When connecting to SQL Server 2005, this failure may be caused by the
fact that under the default settings SQL Server does not allow remote
connections. (provider: Named Pipes Provider, error: 40 - Could not
open a connection to SQL Server)

真是奇怪了,後來在這裏找到了解決方法,原來加一個@就正常了^__^

SqlConnection conn = new SqlConnection(@"Data Source=DAISYLH/SQLEXPRESS;Initial Catalog=Northwind;Integrated Security=True;Pooling=False");

注:以上是C#的寫法,VB.NET則不需要@
