c# - Unexpected text (System.Int32[]) -
i trying make code computes hold time , press/release times of keys entered through keyboard.
hold time = keyup(i) - keydown(i+1) release_press time = keydown(i+1) - keyup(i) press_press time = keydown(i+1) - keydown(i) release_release time = keyup(i+1) - keyup(i) and code neither error nor warnings ...but when run (system.int32[]) in text boxes hold , press/release times should exhibited. don't know why i'm getting error or error is.

the problem lines following:
textbox3.text = a.tostring();// key duration the tostring() method doesn't make string containing numbers. tells type is. default tostring behavior.
ints display number because have overridden tostring method.
you might want
a[i].tostring(); or might want make sort of aggregate string of array, in case can write function or that.
