SmtpClient.Timeout Property


Gets or sets a value that specifies the amount of time after which a synchronous Send call times out.

Namespace:   System.Net.Mail
Assembly:  System (in System.dll)

member Timeout : int with get, set

Property Value

Type: System.Int32

An Int32 that specifies the time-out value in milliseconds. The default value is 100,000 (100 seconds).

Exception Condition

The value specified for a set operation was less than zero.


You cannot change the value of this property when an email is being sent.

By default, calls to the Send method block until the operation completes. If you set the Timeout property to a positive value, and a Send operation cannot complete in the allotted time, the SmtpClient class throws an SmtpException exception.

To send a message and continue executing in the application thread, use the SendAsync method.

The following code example demonstrates getting and setting the time-out value.
