尝试为文件D:\test.mdf附加自动命名的数据库失败 [英] An attempt to attach an auto-named database for file D:\test.mdf failed
问题描述
我在连接数据库时遇到问题。我收到此错误
尝试为文件D附加自动命名的数据库:\abc\abc\bin\Debug\test.mdf失败。存在一个具有相同名称的数据库,或者无法打开指定的文件,或者它位于UNC共享上。
我的连接字符串:
< connectionstrings>
< add name =abc.Properties.Settings.abcConnectionString
connectionString =Data Source =。 \ SQLEXPRESS; AttachDbFilename = | DataDirectory | \test.mdf; Integrated Security = true/>
我尝试过:
尝试为文件D附加自动命名的数据库:\ abc.mdf失败
AttachDBFileName 是邪恶的,请看这个问题:

my connection string :
<connectionstrings>
<add name="abc.Properties.Settings.abcConnectionString"
connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\test.mdf;Integrated Security=true" />
What I have tried:
