c# - Call Interclass Asynch Task

I am kinda new to Xamarin.Android and still have a steep learning curve ;-). But i approached a problem which i don't find a solution even after a few days of googling and YouTube-ing.

Do somebody know how to call a async Task from another Class?

i want to call the public async Task ReadStringAsync() from the class MainActivity. How can i do that?

i want to call this:

class TextfileRead  {      string[] StrData;        String filename = "Arbeitszeiten.txt";      String filepath = "myFileDir";      String fileContent = "";        public async Task<string> ReadStringAsync()      {          var backingFile = Path.Combine(filepath, filename);            if (backingFile == null || !System.IO.File.Exists(backingFile))          {              return "oO, irgendwas ging schief";          }            string line;          using (var reader = new StreamReader(backingFile, true))          {              //string line;              while ((line = await reader.ReadLineAsync()) != null)              {                  //return line;              }          }          return line;      }
