How to Print an Array's Contents in C#?

Several methods of printing array contents in C#

Unlike Java, C# has no direct equivalent to Java's System.out.print(Arrays.toString(alg.id)) method for printing array contents. You can use the following methods:

1. foreach loop:

Use foreach to loop through the array elements and print them one by one:

<code class="language-csharp">foreach (var item in yourArray)
{
    Console.WriteLine(item.ToString());
}</code>

2. Lambda expression combined with ToList:

Alternatively, you can use a Lambda expression to iterate over the array elements and add them to a list, then print the list:

<code class="language-csharp">yourArray.ToList().ForEach(i => Console.WriteLine(i.ToString()));</code>

3. Array.ForEach method:

In C#, the preferred way to print array elements is to use the Array.ForEach<T> method:

<code class="language-csharp">Array.ForEach(yourArray, Console.WriteLine);</code>

This method takes a Lambda expression as a parameter and executes the expression for each element in the array.

4. Single line printing:

If you want to print the array contents in one line, you can use the following format string:

<code class="language-csharp">Console.WriteLine("[{0}]", string.Join(", ", yourArray));</code>

This will generate output in the format [<item1>, <item2>, ..., <itemn>].
