c# - How to make each method wait to complete another inside of parallel.Foreach? -

i have big problem "parallel for" using task parallel. want make methods , functions synchronous (wait on each other).

parallel.for(items, item=> {     var = myclass1.function(foo.x);     var b = myclass2.function(zoo.y, b.z);  ---> should wait "a" result...     var c = myclass2.method1(a.x,b.z); -----> should wait b result... });   

how can that?

parallel.for run in parallel across collection of items. each item processes, invoke given delegate synchronously. meaning, execute myclass1.function myclass2.function myclass2.method1. assuming methods synchronous, , you're not doing in background threads inside of them.

imagine this:

                items   |          |          |          |  item1:      item2:     item3:     item4: function1  function1  function1  function1 function2  function2  function2  function2 method1    method1    method1    method1
