SqlConnectionStringBuilder.IntegratedSecurity Property

Note: This property is new in the .NET Framework version 2.0.

Gets or sets a Boolean value that indicates whether User ID and Password are specified in the connection (when false) or whether the current Windows account credentials are used for authentication (when true).

Namespace: System.Data.SqlClient
Assembly: System.Data (in system.data.dll)

public bool IntegratedSecurity { get; set; 
/** @property */
public boolean get_IntegratedSecurity ()

/** @property */
public void set_IntegratedSecurity (boolean value)

public function get IntegratedSecurity () : boolean

public function set IntegratedSecurity (value : boolean)

Property Value

The value of the IntegratedSecurity property, or false if none has been supplied.

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

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.

NoteNote

This example includes a password to demonstrate how SqlConnectionStringBuilder works with connection strings. In your applications, we recommend that you use Windows Authentication. If you must use a password, do not include a hard-coded password in your application.

using System.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();
