Options for initializing a string array

Question

What options do I have when initializing string[] object?

Solution 1

You have several options:

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"; // ...

Solution 2

Basic:

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

or

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

Advanced: From a List

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

From StringCollection

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

Solution 3

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

Don't forget the string[] items = { "Item1", "Item2", "Item3", "Item4" }; shortcut.

Can someone add an example of "From a List" above but for the case of loading the contents of 2 lists into a 2 dimensional array (not jagged ie double[,])?
