Description
You currently cannot use an index initializer to populate a fixed-sized buffer. For example:
struct Body
{
public fixed double V[3];
}
new Body
{
V =
{
[0] = 1,
[1] = 2,
[2] = 3
}
};
emits on V = an error:
error CS1666: You cannot use fixed size buffers contained in unfixed expressions. Try using the fixed statement.
Firstly, if this is intended behavior, I would at least improve the error message, especially since trying to pin Body.V emits
error CS0213: You cannot use the fixed statement to take the address of an already fixed expression
so you cannot even resolve this issue in the way the error message suggests. However, I think that it should work as expected (and I believe that it can be supported within the current parameters of the language).
