c# - Merging the values of two dictionaries -

this question has reply here:

merging dictionary containing list in c# 4 answers c# merging 2 dictionaries 4 answers

was hoping inquire advice.

i have 2 dictionaries

dictionary<string, list<string>> dict = new dictionary<string, list<string>>(); dictionary<string, list<string>> dictfinal = new dictionary<string, list<string>>();

in both cases key values same both represent different lists of string values.

what want have 1 dictionary same key values , lists of string values merged in 1 dictionary

i did start serious of loops realised perhaps not best solution

foreach (var fin in dictfinal) { foreach (var valfin in fin.value) { foreach (var kvp in dict) { foreach (var v in kvp.value) { } } } }

is there improve way bringing these 2 dictionaries 'together'?

dictionary<string, list<string>> d1 = new dictionary<string, list<string>>(); dictionary<string, list<string>> d2 = new dictionary<string, list<string>>(); d2.tolist().foreach(x => { if (d1.containskey(x.key)) d1[x.key].addrange(x.value); else d1.add(x.key, x.value); });

that merge both dictionaries d1.

without tolist()

foreach(var x in d1) { if (d1.containskey(x.key)) d1[x.key].addrange(x.value); else d1.add(x.key, x.value); }
