How do I make a System.Collection.BitArray readonly? I looked for the follwing but without any success yet...

• myBitArray.IsReadOnly = true; does not work as the property has only a getter.

• myBitArray.SetReadOnly() does not work as there is no such method.

• new BitArray(myBitArray, readonly: true) does not work as there is no such constructor overload.

• myBitArray.Clone(readonly: true) does not work as there is no such method overload.

• myBitArray.AsReadOnly() does not work as there is no such extension method.

• And neither is there a BitArrayBuilder...

What am I missing?

(Am using .NET 4.8 to 6.0, multi-targeting)

From the documentation of BitArray.IsReadOnly

This property is always false.

BitArray implements the IsReadOnly property because it is required by the System.Collections.IList interface.

That explanation seem a bit odd to me, since BitArray does not seem to implement IList, only ICollection. But that is the explanation given.

If you are in some particular need for a read only bitArray an option might be to create your own class or a wrapper.
