Initialize a Jagged Array the LINQ Way

Question

I have a 2-dimensional jagged array (though it\'s always rectangular), which I initialize using the traditional loop:

var myArr = new double[rowCount][];
for         


        

Answer 1

The behavior is correct - Repeat() returns a sequence that contains the supplied object multiple times. You can do the following trick.

double[][] myArr = Enumerable
    .Repeat(0, rowCount)
    .Select(i => new double[colCount])
    .ToArray();
