How to initialize a string array in C#?

In C#, there are several ways to initialize a string array:

1. Initialize a string array with specified elements using curly braces {}.

string[] arr1 = {"apple", "banana", "orange"};

1. Initialize an empty string array with a specified size using the new keyword, and then assign values using indexes.

string[] arr2 = new string[3];
arr2[0] = "apple";
arr2[1] = "banana";
arr2[2] = "orange";

1. Initialize a string array with default values by using the new keyword and initializing the elements’ values.

string[] arr3 = new string[3] {"apple", "banana", "orange"};

1. Initialize a string array using the static methods of the Array class.

string[] arr4 = Array.Empty<string>();  // 初始化一个空的字符串数组
string[] arr5 = Array.CreateInstance(typeof(string), 3) as string[];  // 初始化指定大小的字符串数组

The above are several common ways to initialize string arrays. Choose the appropriate method based on your specific needs.
