Beware of recursion on getter/setter methods

Question Received:

      The Application is not responding apparently.

Solution:

     Check the code for any defects like recursion in the statement and methods.
     Defect I have found from the getter/setter methods.
     private string _mail;
     public string Mail

     {

          get

          {

               return _mail;

          }

          set

          {

              if(condition)

              {

                   Mail="mail@daemon.com";

              }

          }
     }
     public DataSource()

     {

          Mail="mail@daemon.com";

     }

[Note:]
The culprit is,
       In setter method, Mail="mail@daemon.com" makes it call the setter method recursively.
