ConnectionTimeout Property

SqlConnection.ConnectionTimeout Property


Gets the time to wait while trying to establish a connection before terminating the attempt and generating an error.

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

public override int ConnectionTimeout { get; }

Property Value

Type: System.Int32

The time (in seconds) to wait for a connection to open. The default value is 15 seconds.

Exception Condition

The value set is less than 0.

You can set the amount of time a connection waits to time out by using the ConnectTimeout or Connection Timeout keywords in the connection string. A value of 0 indicates no limit, and should be avoided in a ConnectionString because an attempt to connect waits indefinitely.

The following example creates a SqlConnection and sets the Connection Timeout to 30 seconds in the connection string. The code opens the connection and displays the ConnectionTimeout property in the console window.
