How do you randomize an item in a list C#?

How do you randomize an item in a list C#?

List OriginalList = new List(); List TempList = new List(); Random random = new Random(); int length = OriginalList. Count; int TempIndex = 0; while (length > 0) { TempIndex = random. Next(0, length); // get random value between 0 and original length TempList.

How do you randomize an array in C#?

Shuffle an Array With the Random Class in C The Random. Next() method generates a random integer value. We can use the Random. Next() method with LINQ to shuffle an array in C#.

How do I shuffle a string in C#?

Check this example:

  1. List list = new List { “a”, “b”, “c”, “d”, “e” };
  2. Random rnd = new Random();
  3. List shuffled_list = list. OrderBy( i => rnd. Next() ). ToList();
  4. textBox1. Text = string. Join( ” “, shuffled_list );

How do I copy a list in C#?

Now declare a string array and use the CopyTo() method to copy. string[] arr = new string[20]; list1. CopyTo(arr); Let us see the complete code to copy a list into a one-dimensional array.

How do you shuffle an array algorithm?

The shuffle is random as the algorithm by selecting uniformly an element which has not been selected. For example if the element at position 2 is selected it can be exchanged with all elements at position 2 until position n-1 (as the list /array has 0 – n-1 positions).

How do you shuffle an array of numbers?

Shuffle Array using Random Class We can iterate through the array elements in a for loop. Then, we use the Random class to generate a random index number. Then swap the current index element with the randomly generated index element. At the end of the for loop, we will have a randomly shuffled array.

How do you randomize a string in Python?

To shuffle strings or tuples, use random. sample() which creates a new object. random. sample() returns a list even when a string or tuple is specified to the first argument, so it is necessary to covert it to a string or tuple.
