Given an implicit conversion C1
that converts from a type S
to a type T1
, and an implicit conversion C2
that converts from a type S
to a type T2
, the better conversion of the two conversions is determined as follows:
T1
and T2
are the same type, neither conversion is better.S
is T1
, C1
is the better conversion.S
is T2
, C2
is the better conversion.T1
to T2
exists, and no implicit conversion from T2
to T1
exists, C1
is the better conversion.T2
to T1
exists, and no implicit conversion from T1
to T2
exists, C2
is the better conversion.T1
is sbyte
and T2
is byte
, ushort
, uint
, or ulong
, C1
is the better conversion.T2
is sbyte
and T1
is byte
, ushort
, uint
, or ulong
, C2
is the better conversion.T1
is short
and T2
is ushort
, uint
, or ulong
, C1
is the better conversion.T2
is short
and T1
is ushort
, uint
, or ulong
, C2
is the better conversion.T1
is int
and T2
is uint
, or ulong
, C1
is the better conversion.T2
is int
and T1
is uint
, or ulong
, C2
is the better conversion.T1
is long
and T2
is ulong
, C1
is the better conversion.T2
is long
and T1
is ulong
, C2
is the better conversion.If an implicit conversion C1
is defined by these rules to be a better conversion than an implicit conversion C2
, then it is also the case that C2
is a worse conversion than C1
.
