When I put the connection string, the following error appears:
Con = new SqlConnection("Data Source=(localdb)\MSSQLLocalDB;OutrosParametros");
Represents text as a series of Unicode characters
When I put two slashes ( \ ) the error some.
Can I use \\?
The message
Represents text as a series of Unicode characters
is not an error, it is the description of string .
The code actually has an error that is to use \ as literal, this character needs to be escaped.
There are two options for this:
Use \ to escape this character only.
Ex: "Teste\Teste "equals Teste\Teste .
new SqlConnection("Data Source=(localdb)\MSSQLLocalDB;OutrosParametros");
Use @ at the beginning of string . This will do what the text is represented that way. In other words, string turns a string literal (or verbatim string ).
Ex: @"Teste\nTeste" is equal to Teste\nTeste .
new SqlConnection(@"Data Source=(localdb)\MSSQLLocalDB;OutrosParametros");
Place @ before your quotation mark ("")
