c# - Display 'Control Characters' on Button controls as its text -

-

i making virtual keyboard application in win forms, in have 150+ buttons. on these buttons, setting characters [like 'a','d','0','5','#','<' etc.] 'text' of buttons. here have done.

if(keylbl.startswith("0x")) {     // convert number expressed in base-16 integer.      int value = convert.toint32(keylbl, 16);     // char value corrospnding value, , set key label     string btntext = char.convertfromutf32(value);  } else...

here keylbl getting string in hexadecimal representation [e.g 0x41, 0x42, 0x80, 0x81,... 0xff]

now issue is, getting correct value in btntext values 0x7e not able text next strings 0x80. how can symbols corresponding these display buttons' text.
