初始化字符串数组的选项

Question

初始化string[]对象时，我有哪些选项？

Answer 1

您有几种选择：

string[] items = { "Item1", "Item2", "Item3", "Item4" };

string[] items = new string[]
{
  "Item1", "Item2", "Item3", "Item4"
};

string[] items = new string[10];
items[0] = "Item1";
items[1] = "Item2"; // ...

Answer 2

基本：

string[] myString = new string[]{"string1", "string2"};

或

string[] myString = new string[4];
myString[0] = "string1"; // etc.

高级： 从列表中

list<string> = new list<string>(); 
//... read this in from somewhere
string[] myString = list.ToArray();

来自StringCollection

StringCollection sc = new StringCollection();
/// read in from file or something
string[] myString = sc.ToArray();

Answer 3

string[] str = new string[]{"1","2"};
string[] str = new string[4];

Answer 4

MSDN has the skinny on this.
