SQL Database not conecting to login form in asp.net

Hi,

I am very new to programming and have created a login form in Microsoft Visual Studio using asp.net and C#.

In this form I have a "Login" button and the code behind login button is

SqlConnection con = new SqlConnection("Data Source=KYLELT\SQLEXPRESS;Initial Catalog=EmploymentEquity;Integrated Security=True");>

My connection string is "Data Source=KYLELT\SQLEXPRESS;Initial Catalog=EmploymentEquity;Integrated Security=True"

When I run the code i get a "Unrecognized escape sequence" on this line of code with a red underline below the "\" in the code.

I can't connect to my database with this connection string because of the "\", what am I doing wrong?

Regards,

Kyle
