Examples

The following example converts an existing connection string from using SQL Server Authentication to using integrated security. The example does its work by removing the user name and password from the connection string and then setting the IntegratedSecurity property of the SqlConnectionStringBuilder object.

using Microsoft.Data.SqlClient;

class Program
{
    static void Main()
    {
        try
        {
            string connectString =
                "Data Source=(local);User ID=ab;Password=MyPassword;" +
                "Initial Catalog=AdventureWorks";

            SqlConnectionStringBuilder builder =
                new SqlConnectionStringBuilder(connectString);
            Console.WriteLine("Original: " + builder.ConnectionString);

            // Use the Remove method
            // in order to reset the user ID and password back to their
            // default (empty string) values. Simply setting the 
            // associated property values to an empty string won't
            // remove them from the connection string; you must
            // call the Remove method.
            builder.Remove("User ID");
            builder.Remove("Password");

            // Turn on integrated security:
            builder.IntegratedSecurity = true;

            Console.WriteLine("Modified: " + builder.ConnectionString);

            using (SqlConnection connection =
                       new SqlConnection(builder.ConnectionString))
            {
                connection.Open();
                // Now use the open connection.
                Console.WriteLine("Database = " + connection.Database);
            }

        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
        }

        Console.WriteLine("Press any key to finish.");
        Console.ReadLine();
    }
}

Remarks

This property corresponds to the "Integrated Security" and "trusted_connection" keys within the connection string.

If User ID and Password are specified and Integrated Security is set to true, the User ID and Password will be ignored and Integrated Security will be used.

SqlCredential is a more secure way to specify credentials for a connection that uses SQL Server Authentication (Integrated Security=false).
