Hvordan kan jeg indstille en SQL Server-forbindelsesstreng?

.NET DataProvider -- Standardforbindelse med brugernavn og adgangskode

using System.Data.SqlClient;

SqlConnection conn = new SqlConnection();
conn.ConnectionString =
  "Data Source=ServerName;" +
  "Initial Catalog=DataBaseName;" +
  "User id=UserName;" +
  "Password=Secret;";
conn.Open();

.NET DataProvider -- Trusted Connection

SqlConnection conn = new SqlConnection();
conn.ConnectionString =
  "Data Source=ServerName;" +
  "Initial Catalog=DataBaseName;" +
  "Integrated Security=SSPI;";
conn.Open();
