示例1: InferTypeInYieldStatement
private IEnumerable<ITypeSymbol> InferTypeInYieldStatement(YieldStatementSyntax yieldStatement, SyntaxToken? previousToken = null)
{
// If we are position based, then we have to be after the return keyword
if (previousToken.HasValue && (previousToken.Value != yieldStatement.ReturnOrBreakKeyword || yieldStatement.ReturnOrBreakKeyword.IsKind(SyntaxKind.BreakKeyword)))
{
return SpecializedCollections.EmptyEnumerable<ITypeSymbol>();
}
