visual studio 2010 - Distance Converter for inches, feet, and yards in C# -


i new programming, silly question simple answer. application allows users type number, select unit of measurement using, select unit of measurement convert , convert it.

i have 1 error in last line of code keeping working: 'cannot implicitly convert type 'int' 'string'. can please help?

here's code:

   private void convertbutton_click(object sender, eventargs e)     {         int fromdistance;         int todistance;          fromdistance = int.parse(distanceinput.text);         string measureinput = fromlist.items[fromlist.selectedindex].tostring();         string measureoutput = tolist.items[tolist.selectedindex].tostring();          switch (measureinput)         {             case "yards":                 switch (measureoutput)                 {                     case "yards":                         todistance = fromdistance;                         break;                     case "feet":                         todistance = fromdistance * 3;                         break;                     case "foot":                         todistance = fromdistance * 3 * 12;                         break;                 }                 break;             case "feet":                 switch (measureoutput)                 {                     case "feet":                         todistance = fromdistance;                         break;                     case "yards":                         todistance = fromdistance / 3;                         break;                     case "foot":                         todistance = fromdistance * 12;                         break;                 }                 break;             case "foot":                 switch (measureoutput)                 {                     case "foot":                         todistance = fromdistance;                         break;                     case "feet":                         todistance = fromdistance / 12;                         break;                     case "yards":                         todistance = fromdistance / (3 * 12);                         break;                 }                 break;         }         distanceoutput.text = todistance;     } 

distanceoutput.text = todistance.tostring();

looks might used dynamically typed languages? int stored in binary representation, , can represent many different values. .tostring() converts common representation.

btw should not use integer calculated value type, you'll throw away fractional numbers. use double or float, , use math.round(number, decimalpoints) .
