Convert list of float[] to list of double[]

I want to convert a List<float[]> to List<double[]>

List<float[]> f=new List<float[]>();
List<double[]> d=new List<double[]>();

// ...add float arrays to f...

d.AddRange((doulbe[])f); // Cannot convert type float[] to double[]

is there a way to cast this? so that it won't require a for loop, because I have many lists to be converted.

Solution

  • You can use:

    d.AddRange(f.Select(flArray => Array.ConvertAll(flArray, f => (double)f)));

    or:

    f.ForEach(flArray => d.Add(Array.ConvertAll(flArray, f => (double)f)));
