這個專案在XX上面執行會出現System.NullReferenceE

這個專案在XX上面執行會出現System.NullReferenceException的錯誤，因為int length = await args.Data.ReadAsync(buffer, 0, buffer.Length);這字傳返回null，我該如何解決呢?

結果 (英文) 1:

The implementation of this project System.NullReferenceException error occurs in the XX above, because int length = await args.Data.ReadAsync (buffer, 0, buffer.Length); this word is transferred returns null, how can I solve it?

結果 (英文) 2:

The execution of this project on XX will result in a System.NullReferenceException error, because the int length is the await args. Data.ReadAsync (buffer, 0, buffer.) Length); This word is returned to null, how can I solve it?

結果 (英文) 3:

System.nullreferenceexception will occur when this project runs on XX, because int length = await args.data.readasync (buffer, 0, buffer. Length); how can I solve this problem when null is returned?
