        SqlConnectionStringBuilder builder = new SqlConnectionStringBuilder();

        builder["Password"] = null;

        aa = builder.Password;
        Console.WriteLine(aa.Length);

        try
        {
            builder.Password = null;
        }
        catch (ArgumentNullException e)
        {
            Console.WriteLine("{0}", e);
        }
    }
}

Remarks

This property corresponds to the "Password" and "pwd" keys within the connection string.

Setting this property is not recommended. To maintain a high level of security, we strongly recommend that you use the Integrated Security or Trusted_Connection keyword instead. SqlCredential is a more secure way to specify credentials for a connection that uses SQL Server Authentication.

If Password has not been set and you retrieve the value, the return value is Empty. To reset the password for the connection string, pass null to the Item property.

The password must be 128 characters or less.
