In.ReadLine() sometimes skips chars in the beginning string and doesn’t work as would be expected Could this be caused because i have Win7 Pro x64 NET Framework 4.5.2

I use my program through the pipeline in cmd, and i just use ping as an example and test

Screenshot:

1. skipped the first character

2. skipped the first character and second

It happens with async. The method RunScript is async

while(true)
{ 
               try
                {
                    string _str = null;
                    if ((_str = Console.In.ReadLine()) != null) { if (_str != "") {  RunScript(_str, pathScript); } } else { break; }
                    
                }
}

This works without the async method:

while(true)
{ 
                try
                {
                    string _str = null;
                    if ((_str = Console.In.ReadLine()) != null) { if (_str != "") {  Console.WriteLine(_str); } } else { break; }
                    
                }
}
