IArgumentOperation Interface

Definition

Represents an argument to a method invocation.

Current usage: (1) C# argument to an invocation expression, object creation expression, etc. (2) VB argument to an invocation expression, object creation expression, etc.

public interface class IArgumentOperation : Microsoft::CodeAnalysis::IOperation
public interface IArgumentOperation : Microsoft.CodeAnalysis.IOperation
type IArgumentOperation = interface
    interface IOperation
Public Interface IArgumentOperation
Implements IOperation

Remarks

This node is associated with the following operation kinds:

This interface is reserved for implementation by its associated APIs. We reserve the right to change it in the future.

Properties

ArgumentKind

Kind of argument.

ChildOperations

An enumerable of child operations for this operation.

(Inherited from IOperation)
Children
Obsolete.

An array of child operations for this operation. Deprecated: please use ChildOperations.

(Inherited from IOperation)
ConstantValue

If the operation is an expression that evaluates to a constant value, HasValue is true and Value is the value of the expression. Otherwise, HasValue is false.

(Inherited from IOperation)
InConversion

Information of the conversion applied to the argument value passing it into the target method. Applicable only to VB Reference arguments.

IsImplicit

Set to True if compiler generated /implicitly computed by compiler code

(Inherited from IOperation)
Kind

Identifies the kind of the operation.

(Inherited from IOperation)
Language

The source language of the IOperation. Possible values are CSharp and VisualBasic.

(Inherited from IOperation)
OutConversion

Information of the conversion applied to the argument value after the invocation. Applicable only to VB Reference arguments.

Parameter

Parameter the argument matches. This can be null for __arglist parameters.

Parent

IOperation that has this operation as a child. Null for the root.

(Inherited from IOperation)
SemanticModel

Optional semantic model that was used to generate this operation. Non-null for operations generated from source with GetOperation(SyntaxNode, CancellationToken) API and operation callbacks made to analyzers. Null for operations inside a ControlFlowGraph.

(Inherited from IOperation)
Syntax

Syntax that was analyzed to produce the operation.

(Inherited from IOperation)
Type

Result type of the operation, or null if the operation does not produce a result.

(Inherited from IOperation)
Value

Value supplied for the argument.

Methods

Accept(OperationVisitor) (Inherited from IOperation)
Accept<TArgument,TResult>(OperationVisitor<TArgument,TResult>, TArgument) (Inherited from IOperation)

Extension Methods

Descendants(IOperation)

Returns all the descendant operations of the given operation in evaluation order.

DescendantsAndSelf(IOperation)

Returns all the descendant operations of the given operation including the given operation in evaluation order.

GetInConversion(IArgumentOperation)

Gets the underlying Conversion information for InConversion of IArgumentOperation that was created from Visual Basic code.

GetOutConversion(IArgumentOperation)

Gets the underlying Conversion information for OutConversion of IArgumentOperation that was created from Visual Basic code.
