What to do about spaces on my connection string?

问题

For example:

@"Provider=Microsoft.ACE.OLEDB.12.0;Data Source="\\na1b\uj\UP647529\Year 2\Managing Data and Security\Employee.accdb";

Visual studio won't let me run my program until I remove the spaces but thats where the database is..

How can I sort out that connection string to make Visual studio happy?

It looks more like the problem is with the quotation marks in the string literal.

Try replacing each quote with two sets:

@"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=""\\na1b\uj\UP647529\Year 2\Managing Data and Security\Employee.accdb""";

Alternatively, you can ditch the literal and use escape characters:

"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=\"\\\\na1b\\uj\\UP647529\\Year 2\\Managing Data and Security\\Employee.accdb\"";

With all those backslashes in the file path, though, it can be a little hard to read.
