A hashtable is a data structure that consists of a collection of key-value pairs. The hashtable collection uses a hash function to compute the hash code of the key. A hashtable can also be defined as a non-generic collection of key-value pairs. The hash code of each key is computed ... Read More

A Hashtable is a non-generic collection of key-value pairs that are arranged as per the hash code of the key. A Hashtable is used to create a collection that uses a hash table for storage. The hashtable optimizes the lookup by calculating the hash code of each key and stores ... Read More

The hashtable collection in C# is a non-generic collection of elements. Each element of the hashtable is represented as a key-value pair. The keys of the hashtable are non-null and unique. The values can be duplicated and/or null. The Hashtable class of C# Systems.The collections interface is the representation of ... Read More

The hashtable collection in C# is a non-generic collection of items represented as key-value pairs. Each key is a unique, non-null element. The value on the other hand can be duplicated and/or null. The Hashtable class in C# represents the hashtable collection. This class provides the relevant methods to create ... Read More

A hashtable is a collection of key−value pairs. We can access key−value pairs using an iterator. We can also access the keys of the hashtable in a collection. Similarly, we can access the values in a hashtable. Given a hashtable, it is also possible to access the value of a ... Read More

Hashtable collection in C# is a collection of elements wherein each element consist of key-value pair. The key of the element is unique and non-null while the value of the element can be duplicated or even null. The key-and-value pairs are organized based on the hash code of the key. ... Read More

The hashtable collection in C# stores key-value pairs. Each element or item in this collection is a key-value pair i.e. this collection is a double-element collection. The Key is unique, non-null, and used to access the elements in the hashtable. The hashtable collection is immutable and cannot have duplicate elements. ... Read More

A hash table is a collection in C# that holds items identified as key-value pairs. So unlike other data structures like the stack, queue, or ArrayList in C# that store a single value, hashtable in C# stores 2 values. These 2 values i.e. key-value pair form an element of the ... Read More

The hashtable is an organized collection of key-value pairs wherein the keys are arranged as per the hash code of the key calculated using the hash function. While the keys should be non-null and unique in a hashtable, the values can be null and duplicate. The elements in the ... Read More

The hashtable collection in C# is a non-generic collection of key-value pairs that are organized based on the key’s hash code. The key is used to access the elements in the hashtable collection. Hashing helps us to efficiently retrieve data and eliminates the need for costly techniques of searching data. ... Read More
