c# - Async Await top level handling -

i have 10 sql tables need extract data, process, , insert data table. don't want them in parallel, make use of io time.

i have function:

    public async task promoteasync()     {         try         {             using (httransdb transactions = new httransdb())             using (zimportmaster importmaster = new zimportmaster())             using (zmasteraddress masteraddress = new zmasteraddress())             {                 // select out non error rows                 datatable dt = await httransdb.getvalidrowsasync(this.tableconfig.batchid, this.tableconfig.sourcetablename);                   // stuff                  // insert data                 using (httransdb transactionsdb = new httransdb())                 {                     int result = await transactiondb.bulkcopyasync(dt);                 }             }         }         catch (exception e)         {             // log exception , re-throw         }     } 

i run function in foreach loop each table:

    public async task promoteload()     {         // load each batch         foreach (var table in this.tables)         {             await table.promoteasync();         }     } 

my question is, how call function non async method? task.run? don't want start new threads, want process keep running while waiting io.

you can start asynchronous work invoking method:

var promotetask = promoteasync(); 

note returned task represents execution of method.
