Part 4: The program displays string arrays onto the console or as single strings using the string.Join static method. Static Join C# program that uses HashSet on duplicates using System; using System.Collections.Generic; using System.Linq; class Program { static void Main() { // Part 1: input array that contains three duplicate strings.

Static Join C# program that uses HashSet on duplicates using System; using System.Collections.Generic; using System.Linq; class Program { static void Main() { // Part 1: input array that contains three duplicate strings. HashSet<string> stringSet = new HashSet<string> { "a", "b", "c" }; // LINQ's ToList extension method List<string> stringList1 = stringSet.ToList(); // Or just a constructor List<string> stringList2 = new List<string>(stringSet); Personally I'd prefer calling ToList is it means you don't need to restate the type of the list. Dec 24, 2018 · The toString () method of Java HashSet is used to return a string representation of the elements of the Collection. The String representation comprises a set representation of the elements of the Collection in the order they are picked by the iterator closed in square brackets [].This method is used mainly to display collections other than String type (for instance: Object, Integer)in a String Representation. Items in an HashSet are actually objects. In the examples above, we created items (objects) of type "String". Remember that a String in Java is an object (not a primitive type). To use other types, such as int, you must specify an equivalent wrapper class: Integer. Sep 22, 2019 · In the code, given above, we are creating a simple HashSet of the string type and adding the strings to it. We can also add the string, using the Add method. We will see how we can use the Add method in the snippet, given below. Dec 24, 2018 · The toArray() method of Java HashSet is used to form an array of the same elements as that of the HashSet. Basically, it copies all the element from a HashSet to a new array. Syntax: Object[] arr = HashSet.toArray() Parameters: The method does not take any parameters. Return Value: The method returns an array containing the elements similar to ... HashSet<string> stringSet = new HashSet<string> { "a", "b", "c" }; // LINQ's ToList extension method List<string> stringList1 = stringSet.ToList(); // Or just a constructor List<string> stringList2 = new List<string>(stringSet); Personally I'd prefer calling ToList is it means you don't need to restate the type of the list.

We will see how we can use the Add method in the snippet, given below. var uniqueObjs = new HashSet<SomeType>(yourOriginalList); Otherwise you could implement you own IEqualityComnparer-class and pass it to distinct. Note that with the Distinct() approach, you can also look for distinct property values of the object in the list: var uniqueNames = yourlist.Select(obj => obj.Name).Distinct(); and some more... The HashSet<T> constructor has an overload that lets you pass in a custom IEqualityComparer<string>. There are a few of these defined for you already in the static StringComparer class, a few of which ignore case. For example: var set = new HashSet<string>(StringComparer.OrdinalIgnoreCase); set.Add("john"); Debug.Assert(set.Contains("JohN")); I have a HashSet<string> that is added to periodically. What I want to do is to cast the entire HashSet to a string without doing a foreach loop. Does anybody have an example? I have a HashSet<string> that is added to periodically.
