c# - Task.Start fails when continuation actions are not inline -

-

what wrong following code? task.start fails index out of range exception. more clear.. failing because value coming 3 in loop !!!

actionprovider m1 = new actionprovider(); actionprovider m2 = new actionprovider(); actionprovider m3 = new actionprovider();  list<action> actions = new list<action>()  {     ()=> { m2.doit(); },      ()=> { m3.doit(); },  };  task t = new task(() => { m1.doit(); });  (int = 0; < actions.count; i++) {     t.continuewith(t1 => actions[i]()); }  t.start();

it because reuse same variable, i, several times. when execute task has been incremented.

try change for-loop follows:

    (int = 0; < actions.count; i++)     {         var action = actions[i];         t.continuewith(t1 => action());     }

the difference here create copy of variable pass continuewith.
