Initializing a C# array with multiple copies of the same element

Question

In the C++ Standard Template Library (STL), it is possible for example to create a vector consisting of multiple copies of the same element, using this constructor:

Answer 1

What about this?

double[] v = Enumerable.Repeat(x, n).ToArray();

EDIT: I just did a small benchmark; to create 1000 arrays of 100000 elements each, using a loop is about 3 times faster that Enumerable.Repeat.

Repeat 
00:00:18.6875488 

Loop 
00:00:06.1628806 

So if performance is critical, you should prefer the loop.
