Capture Stored Procedure print output in .NET

You can do this by adding an event handler to the InfoMessage event on the connection.

 myConnection.InfoMessage += new SqlInfoMessageEventHandler(myConnection_InfoMessage);

    void myConnection_InfoMessage(object sender, SqlInfoMessageEventArgs e)
    {
       Console.WriteLine(e.Message);
    }

This is really handy if you want to capture Print output in LinqPad's output console:

SqlConnection conn = new SqlConnection(ConnectionString);
//anonymous function to dump print statements to output console
conn.InfoMessage += (object obj, SqlInfoMessageEventArgs e)=>{
                e.Message.Dump();
            };
