推荐答案

问题出在这一行:

The problem is in this line:

Dim conn As New SqlConnection("Data Source=.\\SQLEXPRESS;AttachDbFilename="|DataDirectory|Copy of Regstr.mdf";Integrated Security=True;User Instance=True")

将其更改为:

Change that into this:

Dim conn As New SqlConnection("Data Source=.\\SQLEXPRESS;AttachDbFilename=""|DataDirectory|Copy of Regstr.mdf"";Integrated Security=True;User Instance=True")

希望这会有所帮助.

Hope this helps.
