Define Array and Keys in a literal way - C#

Trying to consolidate this...

string[] array = new string[];

开发者_开发技巧array[0] = "Index 0";
array[3] = "Index 3";
array[4] = "index 4";

Into one line...

Example in PHP

$array = array( 0 => "Index 0", 3 => "Index 3", 4 => "Index 4" );

I know I can do this

string[] array = { "string1", "string2", "string3" }

But how would i get the proper indexes in there?

It sounds like you're really after a Dictionary<int, string> rather than a traditional C# array:

var dictionary = new Dictionary<int, string>
{
    { 0, "Index 0" },
    { 3, "Index 3" },
    { 4, "Index 4" }
};

In C# you can't. If you wanted specific indexes you'd have to pass in null values to hold the place of the empty object.

It sounds like you're really after a Dictionary<TKey, TValue> instead.

As far I know, you can't skip index numbers in regular array (e.g. 0,1,2 and then 4 without 3). You need to use different data structure like Dictionary or Hashtable.

Hashtable ht = new Hashtable()
{
    {"key1", "value1"},
    {"key2", "value2"}
};

From my understanding you cannot define arrays in the way you want. Other posters have indicated you can use associative arrays (Dictionaries)

At best you can create a workaround:

string[] array = {"array0", "", "array2", "array3"};

or

string[] array = new string[4]; array[0] = "array0"; array[2] = "array2";
