示例1: WhichConversionIsBetter
public BetterType WhichConversionIsBetter(CType argType,
CType p1, CType p2)
{
// 7.4.2.4 Better conversion from type
//
// Given a conversion C1 that converts from a type S to a type T1 and a conversion C2
// that converts from a type S to a type T2, the better conversion of the two conversions
// is determined as follows:
//* If T1 and T2 are the same type, neither conversion is better
//* If S is T1, C1 is the better conversion.
//* If S is T2, C2 is the better conversion.
//* If an implicit conversion from T1 to T2 exists and no implicit conversion from T2 to
// T1 exists, C1 is the better conversion.
//* If an implicit conversion from T2 to T1 exists and no implicit conversion from T1 to
// T2 exists, C2 is the better conversion.
//
// [Otherwise, see table above for better integral type conversions.]
