示例1: CanRemoveTypeFromParameter
private static bool CanRemoveTypeFromParameter(
SyntaxNode node,
SemanticModel semanticModel,
CancellationToken cancellationToken)
{
// We reduce any the parameters that are contained inside ParameterList
if (node != null && node.IsParentKind(SyntaxKind.ParameterList) && node.Parent.IsParentKind(SyntaxKind.ParenthesizedLambdaExpression))
{
var parameterSyntax = (ParameterSyntax)node;
if (parameterSyntax.Type != null)
{
var annotation = new SyntaxAnnotation();
var newParameterSyntax = parameterSyntax.WithType(null).WithAdditionalAnnotations(annotation);
var oldLambda = node.FirstAncestorOrSelf<ParenthesizedLambdaExpressionSyntax>();
var newLambda = oldLambda.ReplaceNode(parameterSyntax, newParameterSyntax);
var speculationAnalyzer = new SpeculationAnalyzer(oldLambda, newLambda, semanticModel, cancellationToken);
newParameterSyntax = (ParameterSyntax)speculationAnalyzer.ReplacedExpression.GetAnnotatedNodesAndTokens(annotation).First();
var oldSymbol = semanticModel.GetDeclaredSymbol(parameterSyntax, cancellationToken);
var newSymbol = speculationAnalyzer.SpeculativeSemanticModel.GetDeclaredSymbol(newParameterSyntax, cancellationToken);
if (oldSymbol != null &&
newSymbol != null &&
oldSymbol.Type == newSymbol.Type)
{
