将字符串数组转换为C＃中的字符串集合

Question

I'm facing a problem in my code, where I have properties of two different models whose type cannot be changed by me. One is a string array and one is a collection of string. Now I need to add all the elements in the string array to the collection. I'm providing a sample code below.

Collection<string> collection = new Collection<string>();
string[] arraystring = new string[]{"Now","Today","Tomorrow"};
collection.Add(/*Here I need to give the elements of the above array*/);

Note: I cannot change the Collection to ICollection. It has to be Collection only.

Answer 1

If the Collection is already created you can enumerate the items of the array and call Add

Collection<string> collection = new Collection<string>();
string[] arraystring = new string[]{"Now","Today","Tomorrow"};
foreach(var s in arrayString)
    collection.Add(s);

Otherwise you can initialize a Collection from an array of strings

string[] arraystring = new string[]{"Now","Today","Tomorrow"};
Collection<string> collection = new Collection<string>(arraystring);

Answer 2

使用正确的ctor，传入数组：

Collection<string> collection = new Collection<string>(arraystring);

Answer 3

You can give your string array by parameter to Collection<string> ctor, like here:

var collection = new Collection<string>(new[] { "Now", "Today", "Tomorrow" });

About Collection<T> you can read here: https://msdn.microsoft.com/ru-ru/library/ms132397(v=vs.110).aspx .

Answer 4

For a clean solution, you could use the ForEach static method of Array like so:

Collection<string> collection = new Collection<string>();
string[] arraystring = new string[] { "Now", "Today", "Tomorrow" };
Array.ForEach(arraystring, str => collection.Add(str));
