What are the Different Array Initialization Syntaxes in C#?

C#array initialization method Detailed explanation

C# offers a variety of array initialization syntax:

Create a new array with the default value:

• <code class="language-csharp">int[] numbers = new int[5]; </code>

  Use the initial value to create a new array:

• The direct use of value initialization of the array:

  <code class="language-csharp">string[] names = new string[] { "John", "Mary", "Bob" };</code>

• Create a new array with initialized expressions:

  <code class="language-csharp">int[] numbers = { 1, 2, 3, 4, 5 };</code>

• Collection expression (new features of C# 12):

  <code class="language-csharp">int[] numbers = new[] { 1, 2, 3, 4, 5 };</code>

• Supplementary description:

  <code class="language-csharp">int[] numbers = [1, 2, 3, 4, 5];</code>

  The first two grammar can use
keywords (c# 3 introduced) for type inference.

The third grammar needs to be explicitly declared in front of the bracket. The fourth grammar uses

expression, which also supports type inference.

• Collection expression grammar (fifth) is very useful when it cannot infer the target type from the initialization device. It is also suitable for span and list. var
