If you want to provide a timeout for a particular query, then CommandTimeout is the way forward.

Its usage is:

command.CommandTimeout = 60; //The time in seconds to wait for the command to execute. The default is 30 seconds.

You could always add it to your Connection String   connect timeout 180

I found an excellent blogpost on this subject  https   improve dk controlling-sqlconnection-timeouts  Basically  you either set Connect Timeout in the connection string  or you set ConnectionTimeout on the command object  Be aware that the timeout time is in seconds

Old post but as it comes up for what I was searching for I thought I d add some information to this topic  I was going to add a comment but I don t have enough rep   As others have said   connection ConnectionTimeout is used for the initial connection   command CommandTimeout is used for individual searches  updates  etc   But   connection ConnectionTimeout is also used for committing and rolling back transactions   Yes  this is an absolutely insane design decision   So  if you are running into a timeout on commit or rollback you ll need to increase this value through the connection string

A cleaner way is to set connectionString in xml file  for example Web Confing WepApplication  or App Config StandAloneApplication      lt connectionStrings gt       lt remove name  myConn   gt       lt add name  myConn  connectionString  User ID sa Password XXXXX Initial Catalog qualitaBorri Data Source PC NAME SQLEXPRESS Connection Timeout 60   gt     lt  connectionStrings gt    By code you can get connection in this way   public static SqlConnection getConnection             string conn   string Empty          conn   System Configuration ConfigurationManager ConnectionStrings  myConn   ConnectionString          SqlConnection aConnection   new SqlConnection conn           return aConnection      You can set ConnectionTimeout only you create a instance  When instance is create you don t change this value

You can set the timeout value in the connection string  but after you ve connected it s read-only  You can read more at http   msdn microsoft com en-us library system data sqlclient sqlconnection connectiontimeout aspx  As Anil implies  ConnectionTimeout may not be what you need  it controls how long the ADO driver will wait when establishing a new connection  Your usage seems to indicate a need to wait longer than normal for a particular SQL query to execute  and in that case Anil is exactly right  use CommandTimeout  which is R W  to change the expected completion time for an individual SqlCommand

You can set the connection timeout to the connection level and command level      Add  Connection Timeout 10  to the connection string  Now connection timeout is 10 seconds    var connectionString    Server myServerAddress Database myDataBase User Id myUsername Password myPassword Connection Timeout 10   using  var con   new SqlConnection connectionString             Set the of CommandTimeout property to SqlCommand   var connectionString    Server myServerAddress Database myDataBase User Id myUsername Password myPassword   using  var con   new SqlConnection connectionString          using  var cmd  new SqlCommand                  cmd CommandTimeout   10
