Question

Something like

char[] a = new char[] { 'a', 'b', 'c', 'd' };<br>
Console.WriteLine(a);

works nicely with C#.
If the type of the array is integer this does not work any longer.
It has to be coded as

for (int k = 0; k < a.Length; k++) Console.Write(a[k]); Console.WriteLine();

This looks rather lame to me. Is there a more succinct way to do so?
For example some way which expands WriteLine(a) in a loop-free way to

WriteLine("{0},{1},{2},...,{a.Length-1}", a[0],a[1],a[2],...,a[a.Length-1]);

Perhaps there is some neat Linq trick?

Answer 1

How about String.Join ?
Beginning with .Net Framework 4, the second argument is an object[]:

String.Join Method (String, Object[])

Concatenates the elements of an object array, using the specified separator between each element.

Trying a snippet in Visual Studio 2010, targeting framework 4:

    int[] a = new int[] {1,2,3,4,5,6,7 };
    Console.WriteLine(String.Join(",", a));

Produces:

1,2,3,4,5,6,7
