// The reason this class exists is that for code like this:
|
||||
// int i = ...;
|
||||
// long n = 0;
|
||||
// n = n + (long)i;
|
||||
// The resolver will produce (and process) an CastResolveResult for the cast,
|
||||
// (with Conversion = implicit numeric conversion)
|
||||
// and then pass it into CSharpResolver.ResolveBinaryOperator().
|
||||
// That method normally wraps input arguments into another conversion
|
||||
// (the implicit conversion applied by the operator).
|
||||
// However, identity conversions do not cause the creation of ConversionResolveResult instances,
|
||||
// so the OperatorResolveResult's argument will be the CastResolveResult
|
||||
// of the cast.
|
||||
// Without this class (and instead using ConversionResolveResult for both purposes),
|
||||
// it would be hard for the conversion-processing code
|
||||
// in the ResolveVisitor to distinguish the existing conversion from the CastExpression
|
||||
// from an implicit conversion introduced by the binary operator.
|
||||
// This would cause the conversion to be processed yet again.
|
||||
// The following unit tests would fail without this class:
|
||||
// * CastTests.ExplicitConversion_In_Assignment
|
||||
// * FindReferencesTest.FindReferencesForOpImplicitInAssignment_ExplicitCast
|

// * CS0029InvalidConversionIssueTests.ExplicitConversionFromUnknownType
