I have a dictionary which uses ulong as key and a structure as values, i.e.
public Dictionary<UInt64, OptimalOutputs> What_to_do>
Where optimaloutput structure is
public struct OptimalOutputs { public short gotoschool; public short goForDining; public short GoToAcademy; } How can I iterate in dictionary to print, every key along with values? I tried keyvalue pair but in vain
foreach(KeyValuePair<UInt64, OptimalOutputs> pair in dict) { Console.WriteLine("Key: {0} Values: {1},{2},{3}", pair.Key, pair.Value.gotoschool, pair.Value.goForDining, pair.Value.GoToAcademy); } You could also override ToString in your struct which helps f.e. debugging:
public struct OptimalOutputs { public short GotoSchool; public short GoForDining; public short GoToAcademy; public override string ToString() { return string.Format("{0}, {1}, {2}", GoForDining, GotoSchool, GoToAcademy); } } Now you can use this shorter version (ToString is called implicitly):
foreach (KeyValuePair<UInt64, OptimalOutputs> pair in dict) { Console.WriteLine("Key: {0} Values: {1}", pair.Key, pair.Value); } 
You can simply use foreach iteration:
foreach (KeyValuePair<UInt64, OptimalOutputs> pair in dictionary) { Console.WriteLine(string.Format("Key: {0} ", pair.Key); Console.WriteLine(string.Format("Values: {0}, {1}, {2}", pair.Value.goForDining, pair.Value.gotoschool, pair.Value.GoToAcademy); } Additional:
By the way you can override ToString() for OptimalOutputs model.
public class OptimalOutputs { ... public override string ToString() { return string.Format("Values: {0}, {1}, {2}", goForDining, gotoschool, GoToAcademy); } ... } And then:
foreach (KeyValuePair<UInt64, OptimalOutputs> pair in dictionary) { Console.WriteLine(string.Format("Key: {0} Values: {1}", pair.Key, pair.Value); }
