C# Create and initialize (with non-default value) a readonly flaot array?

I need to create a readonly float array and initialize all of its elements with the value 1.0f. I am trying to use the following syntax but it is showing an error, "The modifier readonly is not valid for this item".

int nRows = SomeData.Rows;
int nCols = SomeData.Cols;
readonly float[] myFloatArray = Enumerable.Repeat(1.0f, nRows * nCols).ToArray();

If you want the content of the array to be readonly, which wouldn't be the case even if you could use the readonly modifier, the closest thing to a readonly array you'll find is a ReadOnlyCollection.

int nRows = SomeData.Rows;
int nCols = SomeData.Cols;
var myFloatArray = Array.AsReadOnly(Enumerable.Repeat(1.0f, nRows * nCols).ToArray());
// var is System.Collections.ObjectModel.ReadOnlyCollection<float>
