C# code looks like

}
[A (D = new object[] { 1 })]
class C {}
Cecil crashes with
InvalidCastException {"Unable to cast object of type 'Mono.Cecil.TypeReference'
to type 'Mono.Cecil.ArrayType'. }
Relevant Cecil code
static CustomAttrib.FixedArg CreateFixedArg (TypeReference type, object
value)
{
CustomAttrib.FixedArg fa = new CustomAttrib.FixedArg ();
if (value is object []) {
fa.SzArray = true;
object [] values = value as object [];
TypeReference obj = ((ArrayType)
type).ElementType;<---------------------
fa.NumElem = (uint) values.Length;
fa.Elems = new CustomAttrib.Elem [values.Length];
for (int i = 0; i < values.Length; i++)
fa.Elems [i] = CreateElem (obj, values [i]);
} else {
fa.Elems = new CustomAttrib.Elem [1];
fa.Elems [0] = CreateElem (type, value);
}
return fa;
}
