示例1: TryGetPrimitiveSize
private static bool TryGetPrimitiveSize(ITypeSymbol type, out int size, ref int largestFieldSize)
{
if (type.IsReferenceType)
{
size = IntPtr.Size;
}
else if (type.IsEnum())
{
var enumType = type.GetEnumUnderlyingType();
if (enumType != null)
{
return TryGetPrimitiveSize(enumType, out size, ref largestFieldSize);
}
// Not sure what to do in this case!
size = sizeof(int);
}
else
{
type.TryGetPrimitiveSize(out size);
}
int largestSizeCandidate = size;
// Decimal is special beast:
// It is not a primitive type and actually has few fields of type int,
// that's why bucket size should be equal to sizeof(int).
// Unfortunately, there is no way to get those fields via type instance of Decimal type.
if (type?.SpecialType == SpecialType.System_Decimal)
{
largestSizeCandidate = sizeof(int);
}
// Bucket size should be changed only when current item's size is greater than
// current current bucket.
if (size > largestFieldSize || largestFieldSize == 0)
{
largestFieldSize = largestSizeCandidate;
}
return size != 0;
