Question

As I am working on one Windows service project, I am finding trouble to integrate below functionality.

1. I need to call 5 different web services on 5 different thread in one call (in single method).

2. I must have to wait for all 5 service's response and then I have to perform next task.

Question: How would I wait for all service's response which is called by each different thread? and then I perform my next task moving further.

Thanks in advance.

If you are using .NET 4.0, you can use the Task Parallel Library.

Start each web service call with a new Task and then call Task.WaitAll passing arraying of tasks created.

Task[] taskList = new Task[5];
taskList[0] = System.Threading.Tasks.Task.Factory.StartNew(()=> ServiceCall1());
taskList[1] = System.Threading.Tasks.Task.Factory.StartNew(()=> ServiceCall2());
taskList[2] = System.Threading.Tasks.Task.Factory.StartNew(()=> ServiceCall3());
taskList[3] = System.Threading.Tasks.Task.Factory.StartNew(()=> ServiceCall4());
taskList[4] = System.Threading.Tasks.Task.Factory.StartNew(()=> ServiceCall5());
System.Thread.Tasks.Task.WaitAll(taskList);
