SqlConnectionStringBuilder.ConnectTimeout Property

Gets or sets the length of time (in seconds) to wait for a connection to the server before terminating the attempt and generating an error.

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

public int ConnectTimeout { get; set; }

Property Value

Type: System.Int32
The value of the ConnectTimeout property, or 15 seconds if no value has been supplied.

This property corresponds to the "Connect Timeout", "connection timeout", and "timeout" keys within the connection string.

The following example first displays the contents of a connection string that does not specify the "Connect Timeout" value, sets the ConnectTimeout property, and then displays the new connection string.


using System.Data.SqlClient;

class Program
{
    static void Main()
    {
        try
        {
            string connectString =
                "Server=(local);Initial Catalog=AdventureWorks;" +
                "Integrated Security=true";
            SqlConnectionStringBuilder builder =
                new SqlConnectionStringBuilder(connectString);
            Console.WriteLine("Original: " + builder.ConnectionString);
            Console.WriteLine("ConnectTimeout={0}",
                builder.ConnectTimeout);
            builder.ConnectTimeout = 100;
            Console.WriteLine("Modified: " + builder.ConnectionString);

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

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