Class ParameterizedType

Namespace
ICSharpCode.Decompiler.TypeSystem
Assembly
ICSharpCode.Decompiler.dll

ParameterizedType represents an instance of a generic type. Example: List<string>

public sealed class ParameterizedType : IType, INamedElement, IEquatable<IType>
Inheritance
ParameterizedType
Implements
Inherited Members
Extension Methods

Remarks

When getting the members, this type modifies the lists so that type parameters in the signatures of the members are replaced with the type arguments.

Constructors

ParameterizedType(IType, IEnumerable<IType>) 

public ParameterizedType(IType genericType, IEnumerable<IType> typeArguments)

Parameters

genericType IType
typeArguments IEnumerable<IType>

Properties

DeclaringType

Gets the parent type, if this is a nested type. Returns null for top-level types.

public IType DeclaringType { get; }

Property Value

IType

DirectBaseTypes 

public IEnumerable<IType> DirectBaseTypes { get; }

Property Value

IEnumerable<IType>

FullName 

public string FullName { get; }

Property Value

string

GenericType 

public IType GenericType { get; }

Property Value

IType

IsByRefLike

Gets whether this type is "ref-like": a ByReferenceType or "ref struct".

public bool IsByRefLike { get; }

Property Value

bool

IsReferenceType 

public bool? IsReferenceType { get; }

Property Value

bool?

Kind

Gets the type kind.

public TypeKind Kind { get; }

Property Value

TypeKind

Name 

public string Name { get; }

Property Value

string

Namespace

Gets the full name of the namespace containing this entity.

public string Namespace { get; }

Property Value

string

Nullability

Gets the nullability annotation on this type.

public Nullability Nullability { get; }

Property Value

Nullability

ReflectionName 

public string ReflectionName { get; }

Property Value

string

TypeArguments

Gets the type arguments passed to this type. If this type is a generic type definition that is not parameterized, this property returns the type parameters, as if the type was parameterized with its own type arguments (class C<T> { C<T> field; }).

public IReadOnlyList<IType> TypeArguments { get; }

Property Value

IReadOnlyList<IType>

TypeParameterCount

Gets the number of type parameters.

public int TypeParameterCount { get; }

Property Value

int

TypeParameters

Gets the type parameters. Returns an empty list if this type is not generic.

public IReadOnlyList<ITypeParameter> TypeParameters { get; }

Property Value

IReadOnlyList<ITypeParameter>

Methods

AcceptVisitor(TypeVisitor) 

public IType AcceptVisitor(TypeVisitor visitor)

Parameters

ChangeNullability(Nullability)

Creates a new type that is a copy of this type, with the changed nullability annotation.

public IType ChangeNullability(Nullability nullability)

Parameters

nullability Nullability

Returns

IType

Equals(IType) 

public bool Equals(IType other)

Parameters
