Question

It is possible to create an array at compile time like;

int[] myValues = new int[] { 1, 2, 3 } ; 

But I would like to do something like this;

List<int> myValues = new List<int>() { 1, 2, 3 }; 

The compiler says No. Is there a way to do this (C# 2.0) without using LINQ (C# 3.0)?

Answer 1

List<int> myValues = new List<int>(new int[] { 1, 2, 3 } ); 

This will create an intermediate array however so there may be a more efficient way of doing the same thing.

EDIT:

John Feminella suggested creating a factory method to accept a list of parameters and return a List which you could implement as follows:

List<T> CreateList<T>(params T[] values) {     return new List<T>(values); } 

which you can use as follows:

List<int> myValues = CreateList(1, 2, 3);
