How Can I Print the Contents of an Array in C#?

Efficiently Displaying C# Array Contents

This guide demonstrates several methods for printing the contents of a C# array, offering alternatives to Java's Arrays.toString() method.

Method 1: foreach Loop

The simplest approach involves a foreach loop:

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

This iterates through each element and prints its string representation.

Method 2: Anonymous Function with ForEach

Using LINQ's ForEach with an anonymous function provides a concise solution:

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

Note that this method first converts the array to a list, which might be less efficient for very large arrays.

Method 3: Single-Line Output with string.Join

For a compact, single-line output:

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

This joins array elements with commas and encloses them in square brackets.

Method 4: Array.ForEach (Most Efficient)

The most efficient method leverages the Array.ForEach<T> method:

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

This directly applies the Console.WriteLine method to each array element, avoiding the overhead of list conversion. This is generally the preferred approach for performance reasons.
