C#, how to return string as result from Async/Await Task

Question

I got Async private method that call 3rd party WCF service and in return it get string value. I have added await to the WCF call but getting error

error

'string' does not contain a definition for GetAwaiter and no accessible extension method accepting first argument of type string

code

 private async Task<string> InitializeCall()
    {
        string response = string.Empty;

        response = await eziClient.GetTransactionsAsync(username, "", BatchNumber.ToString(), "").GetAwaiter().GetResult();
        

        return response;
    }

not sure what I missing here?

Answer 1

Remove .GetAwaiter().GetResult():

 private async Task<string> InitializeCall()
    {
        string response = string.Empty;

        response = await eziClient.GetTransactionsAsync(username, "", BatchNumber.ToString(), "");
        

        return response;
    }

The result of .GetAwaiter().GetResult() was a string, and you can't await a string.
