Hash Table in C#

40k

A hash table is a data structure that is used to implement an associative array. It is a collection of key/value pairs, where the keys are unique identifiers and the values are arbitrary data. The hash function has two main purposes:

  •  It maps an input string to an index in the array.
  •  It determines whether the key exists in the hash table or not.

The following code shows how you can create a hash table using C#:

int[] myHashTable = new int[10];

myHashTable[0] = "A"; myHashTable[1] = "B"; myHashTable[2] = "C"; myHashTable[3] = "D"; myHashTable[4] =

The hash table in C sharp works by using the hash function to generate an index into the array at the time of insertion or retrieval. The index starts from 0 and goes up until it reaches the size of the array minus 1, which is referred to as bucket size.

In C sharp, using a hash table can give us the following benefits:

  • It helps us to find values in an efficient way.
  • It helps us to avoid duplicate entries in our collection.
  • It helps us to avoid collisions between keys and values (when we have more than one item with the same key).

Hashtable can be used to store objects that are not related to each other but have a value in common. These values can be integers, strings, or any other data type.

A hash table is a data structure that maps keys to values. It helps in finding the location of the value associated with a key without having to search through the entire list of entries.
