Class LambdaResolveResult

Namespace

ICSharpCode.Decompiler.CSharp.Resolver

Assembly

ICSharpCode.Decompiler.dll

Represents an anonymous method or lambda expression. Note: the lambda has no type. To retrieve the delegate type, look at the anonymous function conversion.

Constructors

LambdaResolveResult()

protected LambdaResolveResult()

Properties

Body

Gets the resolve result for the lambda body. Returns a resolve result for 'void' for statement lambdas.

public abstract ResolveResult Body { get; }

Property Value

ResolveResult

HasParameterList

Gets whether there is a parameter list. This property always returns true for C# 3.0-lambdas, but may return false for C# 2.0 anonymous methods.

public abstract bool HasParameterList { get; }

Property Value

bool

IsAnonymousMethod

Gets whether this lambda is using the C# 2.0 anonymous method syntax.

public abstract bool IsAnonymousMethod { get; }

Property Value

bool

IsAsync

Gets whether the lambda is async.

public abstract bool IsAsync { get; }

Property Value

bool

IsImplicitlyTyped

Gets whether the lambda parameters are implicitly typed.

public abstract bool IsImplicitlyTyped { get; }

Property Value

bool

Remarks

This property returns false for anonymous methods without parameter list.

Parameters

Gets the list of parameters.

public abstract IReadOnlyList<IParameter> Parameters { get; }

Property Value

IReadOnlyList<IParameter>

ReturnType

Gets the return type of the lambda.

If the lambda is async, the return type includes

Task<T>

public abstract IType ReturnType { get; }

Property Value

IType

Methods

GetChildResults()

public override IEnumerable<ResolveResult> GetChildResults()

Returns

IEnumerable<ResolveResult>

GetInferredReturnType(IType[])

Gets the return type inferred when the parameter types are inferred to be parameterTypes

public abstract IType GetInferredReturnType(IType[] parameterTypes)

Parameters

parameterTypes IType[]

Returns

IType

Remarks

This method determines the return type inferred from the lambda body, which is used as part of C# type inference. Use the ReturnType property to retrieve the actual return type as determined by the target delegate type.

IsValid(IType[], IType, CSharpConversions)

Gets whether the lambda body is valid for the given parameter types and return type.

public abstract Conversion IsValid(IType[] parameterTypes, IType returnType, CSharpConversions conversions)

Parameters

parameterTypes IType[]

returnType IType

conversions CSharpConversions

Returns

Conversion

Produces a conversion with IsAnonymousFunctionConversion=true if the lambda is valid; otherwise returns None.
