     You can fill the dictionary directly in your loop

     private Dictionary<string, Dictionary<string, Dictionary<string, string>>> zooDict = new Dictionary<string, Dictionary<string, Dictionary<string, string>>>();-while (reader.Read()){ var location = reader.GetString(0).Trim(); var animal= reader.GetString(1).Trim(); var Monday= reader.GetValue(1).ToString().Trim(); var Tuesday= reader.GetValue(3).ToString().Trim(); if(!zooDict.ContainsKey(location)) zooDict[location] = new Dictionary<string, Dictionary<string, string>>(); zooDict[location][animal] = new Dictionary<string, string>() { { "MN", Monday }, { "Tu", Tuesday } };}

     As a side note, you might want to consider creating classes to represent your objects, add them to a dictionary or list, and use Newtonsoft Json.net (http://www.newtonsoft.com/json) to serialize them instead of using dictionaries for everything. For example, you can create a class:

     public class Animal{ public string Name { get; set; } public int Monday { get; set; } public int Tuesday { get; set; }}var zooDict = new Dictionary<string, List<Animal>>();// then in your while loop you do this if(!zooDict.ContainsKey(location)) zooDict[location] = new List<Animal>();zooDict[location].Add(new Animal() { /* fill Monday and Tuesday properties */ });

     Of course, you can take this one step further and create a class with properties string Location and List<Animal> Animals, and eliminate dictionaries altogether. It depends on your use case(s) I guess

     you could just have a separate lookup for users:

     Dictionary<string, InfoObject> userLookup;-

     This only of course if you want to optimize for lookup speed, the downside is that addition and removal you have to do now on two separate data structures which have to keep in sync.

     You should overload operator outside class and declare it as friend of the class. For example:

     class Vector { // ... friend Vector operator*(float, Vector);};Vector operator*(float num1, Vector num2){ // ...}

   • C# - dictionary - How to get max of specific class value in dictionary?

     Top Answer

     To get LineInfo with maximum lineDistance you can use Values collection. Since there is no MaxBy in standard LINQ you can achieve similar effect with Aggregate

     :

     var max = lines.Values .Aggregate((acc, curr) => acc.lineDistance > curr.lineDistance ? acc: curr);-

   1. here is a quick implement, i used it to get a 'Matrix' (sruct) from a string. you can have a bigger array and change its values on the run also: typedef struct { int** lines; int isDefined; }mat; mat matA, matB, matC, matD, matE, matF; /* an auxilary struct to be used in a dictionary */.

   Code sample

   struct nlist {

     struct nlist *next;

     char *name;

     char *defn;

   };...

   Mar 27, 2023 · Last Updated : 27 Mar, 2023. C programming language does not provide any direct implementation of Map or Dictionary Data structure. However, it doesn’t mean we cannot implement one. In C, a simple way to implement a map is to use arrays and store the key-value pairs as elements of the array .

   dict.c is a simple implementation of a dictionary in C. It's basically just a linked list of key-value pairs. Here's a usage example: #include <stdio.h> #include <stdlib.h> #include "dict.h" int main ( int argc, char *argv []) {. int n = 12 ; dict *my_dict = dict_new (); dict_set ( my_dict, "hello", "world" ); dict_set ( my_dict, "foo", &n );
