Wait for Async method calls in c#

Question

I have a WCF service as below

public bool RefreshDB()
{
   if (twcPMRefresh())
            status = true;
   if (twcCommonRefresh())
            status = true;
}

The logic inside the methods twcPMRefresh() and twcCommonRefresh() is asynchronous and hence I want to wait till 'twcPMRefresh' exceution is finished execution and then invoke twcCommonRefresh. Both the methods are more are less like below.

public bool twcPMRefresh()
{
     tweets=await
         (from tweet in GetTwitterContext(localProxyIP,fCode).Status
         where tweet.Type == StatusType.User &&
         select tweet)
     .ToListAsync();
     --use 'tweets' list to insert in database
 }

Can please assist on this. Thanks!!

You can use the await async method:

Assuming your twcPMRefresh() and twcCommonRefresh() methods are both ASYNC you can write it like this:

public async bool RefreshDB()
{
   if (await twcPMRefresh())
       status = true;
   if (await twcCommonRefresh())
       status = true;
}

your method RefreshDB() can now be called either way:

bool result = RefreshDB().Result()
bool result = await RefreshDB(); //Needs an async Method or a task to be used.
