Three steps of C # programming

Programming third step to increase response to user event code
The final step is to add a method to capture the button click
Event. Here is the button click Code from Celsius to Fahrenheit:
private void Bnctof_click (Object sender,
EventArgs e) {
Double dtempcel = 0;
Double Dtempfah = 0;
try {dtempcel = TTempCel.Text.ToDouble ();}
catch (Exception) {
Ttempcel.clear ();
Ttempfah.clear ();
Return
}
Dtempfah = 1.8*dtempcel+32;
Ttempfah.text = Dtempfah.tostring ();
Ttempfah.focus ();
Ttempfah.selectionstart = 0;
ttempfah.selectionlength = 0;
Ttempcel.focus ();
Ttempcel.selectionstart = 0;
ttempcel.selectionlength = 0;
}

The following is the code for the Fahrenheit button, which will accomplish the same task, but is just the opposite
The processing:
private void Bnftoc_click (Object sender,
EventArgs e) {
Double dtempcel = 0;
Double Dtempfah = 0;
try {Dtempfah = TTempFah.Text.ToDouble ();}
catch (Exception) {
Ttempcel.clear ();
Ttempfah.clear ();
Return
}
Dtempcel = (dTempFah-32)/1.8;
Ttempcel.text = Dtempcel.tostring ();
Ttempcel.focus ();
Ttempcel.selectionstart = 0;
ttempcel.selectionlength = 0;
Ttempfah.focus ();
Ttempfah.selectionstart = 0;
ttempfah.selectionlength = 0;
}
Next, we need to link the appropriate Click event Capture method with the Click event of the button
Get up. To complete this step, we place the following two lines in the constructor of the class:
Bnctof.click + = new EventHandler
(This.bnctof_click);
Bnftoc.click + = new EventHandler
(This.bnftoc_click);
