Constructors

SignatureComparer()

The default SignatureComparer constructor.

public SignatureComparer()

SignatureComparer(RuntimeContext?)

A SignatureComparer constructor with a parameter for specifying the Flags used in comparisons.

public SignatureComparer(RuntimeContext? context)

Parameters

context RuntimeContext

The runtime context that is assumed when comparing types.

SignatureComparer(RuntimeContext?, SignatureComparisonFlags)

A SignatureComparer constructor with a parameter for specifying the Flags used in comparisons.

public SignatureComparer(RuntimeContext? context, SignatureComparisonFlags flags)

Parameters

context RuntimeContext

The runtime context that is assumed when comparing types.

flags SignatureComparisonFlags

The Flags used in comparisons.

SignatureComparer(SignatureComparisonFlags)

A SignatureComparer constructor with a parameter for specifying the Flags used in comparisons.

public SignatureComparer(SignatureComparisonFlags flags)

Parameters

flags SignatureComparisonFlags

The Flags used in comparisons.

Properties

Default

An immutable default instance of SignatureComparer.

public static SignatureComparer Default { get; }

Property Value

SignatureComparer

Flags

Flags for controlling comparison behavior.

public SignatureComparisonFlags Flags { get; }

Property Value

SignatureComparisonFlags

RuntimeContext

When available, gets the runtime context that is assumed when comparing types.

public RuntimeContext? RuntimeContext { get; }

Property Value

RuntimeContext

Remarks

When null, types are always compared as-is. When non-null, any exported type is resolved first before doing the comparison.

SimpleTypeEquals(ITypeDescriptor, ITypeDescriptor)

Compares two ITypeDescriptors without specializing for unusual kinds of descriptors.

protected virtual bool SimpleTypeEquals(ITypeDescriptor x, ITypeDescriptor y)

Parameters

x ITypeDescriptor

The first ITypeDescriptor to compare

y ITypeDescriptor

The second ITypeDescriptor to compare

Returns

bool

true if x and y are equal; false otherwise

Remarks

This is called by Equals(ITypeDefOrRef?, ITypeDefOrRef?) for non-TypeSignatures. Overrides of this method should, as much as possible, compare x and y directly.

SimpleTypeHashCode(ITypeDescriptor)

Gets the hashcode of a ITypeDescriptor without specializing for unusual kinds of descriptors.

protected virtual int SimpleTypeHashCode(ITypeDescriptor obj)

Parameters

obj ITypeDescriptor

The ITypeDescriptor to get the hashcode of

Returns

int

The computed hashcode

Remarks

This is called by GetHashCode(ITypeDefOrRef) for non-TypeSignatures. Overrides of this method should, as much as possible, compare obj directly.
