What is NameValueCollection?
NameValueCollection is used to store a collection of associated String keys and String values that can be accessed either with the key or with the index. It is very similar to C# HashTable, HashTable also stores data in Key , value format . NameValueCollection can hold multiple string values under a single key.
How do I get value from NameValueCollection?
NameValueCollection collection = GetCollection(); string[] values = collection. GetValues(“partiban”);…Advantage:
- We can store duplicate keys either with different values or the same value.
- Using a key we can get all the values for the single key.
- Single Key, but multiple values.
How do you serialize NameValueCollection?
NameValueCollection Data = new NameValueCollection(); Data. Add(“foo”,”baa”); string json = new JavaScriptSerializer(). Serialize(Data);
Is NameValueCollection case sensitive?
The default comparer is a CaseInsensitiveComparer that uses the conventions of the invariant culture; that is, key comparisons are case-insensitive by default. To perform case-sensitive key comparisons, call the NameValueCollection.
Does C# have hash map?
HashMap is in Java, not C#.
What is hash list in C#?
The Hashtable class represents a collection of key-and-value pairs that are organized based on the hash code of the key. It uses the key to access the elements in the collection. A hash table is used when you need to access elements by using key, and you can identify a useful key value.
What is hashing a string?
Hashing is the process of transforming any given key or a string of characters into another value. This is usually represented by a shorter, fixed-length value or key that represents and makes it easier to find or employ the original string. The most popular use for hashing is the implementation of hash tables.
What is the hash code of a string?
Java String hashCode() A hashcode is a number (object’s memory address) generated from any object, not just strings. This number is used to store/retrieve objects quickly in a hashtable. Here, string is an object of the String class.
What is the hash code?
A hash code is an integer value that is associated with each object in Java. Its main purpose is to facilitate hashing in hash tables, which are used by data structures like HashMap.
