Problems with the consolekeys string C# -

i have question code, supposed write i'm typing.

consolekeyinfo = console.readkey(); if (a.key == consolekey.spacebar) {      console.write(" "); } else if (a.key == consolekey.enter)  {      console.writeline(""); } else {      string b = a.key.tostring();      console.write(b); } 

if i'm clicking on d example prints: dd

but if check b.length equals 1. , if try print b[0] still printing dd. how possible? , how can fix it?

the readkey method both reads key , displays user. hence when hit "d" displays "d", returns consolekeyinfo value , code displays "d". results in "dd" display.

to stop pass true readkey prevent display

consoleinfo = console.readkey(true);
