示例1: IsLambdaExpression
private bool IsLambdaExpression(SemanticModel semanticModel, int position, SyntaxToken token, ITypeInferenceService typeInferrer, CancellationToken cancellationToken)
{
// Typing a generic type parameter, the tree might look like a binary expression around the < token.
// If we infer a delegate type here (because that's what on the other side of the binop),
// ignore it.
if (token.Kind() == SyntaxKind.LessThanToken && token.Parent is BinaryExpressionSyntax)
{
return false;
}
// We might be in the arguments to a parenthesized lambda
if (token.Kind() == SyntaxKind.OpenParenToken || token.Kind() == SyntaxKind.CommaToken)
{
if (token.Parent != null && token.Parent is ParameterListSyntax)
{
return token.Parent.Parent != null && token.Parent.Parent is ParenthesizedLambdaExpressionSyntax;
}
}
// A lambda that is being typed may be parsed as a tuple without names
// For example, "(a, b" could be the start of either a tuple or lambda
// But "(a: b, c" cannot be a lambda
if (token.IsPossibleTupleElementNameContext(position) && token.Parent.IsKind(SyntaxKind.TupleExpression) &&
!((TupleExpressionSyntax)token.Parent).HasNames())
{
position = token.Parent.SpanStart;
}
// Walk up a single level to allow for typing the beginning of a lambda:
// new AssemblyLoadEventHandler(($$
if (token.Kind() == SyntaxKind.OpenParenToken &&
token.Parent.Kind() == SyntaxKind.ParenthesizedExpression)
{
position = token.Parent.SpanStart;
}
// WorkItem 834609: Automatic brace completion inserts the closing paren, making it
// like a cast.
if (token.Kind() == SyntaxKind.OpenParenToken &&
token.Parent.Kind() == SyntaxKind.CastExpression)
{
position = token.Parent.SpanStart;
}
// If we're an argument to a function with multiple overloads,
// open the builder if any overload takes a delegate at our argument position
var inferredTypeInfo = typeInferrer.GetTypeInferenceInfo(semanticModel, position, cancellationToken: cancellationToken);
return inferredTypeInfo.Any(type => GetDelegateType(type, semanticModel.Compilation).IsDelegateType());
