IInvocationOperation Interface

Definition

Represents an invocation of a method.

Current usage: (1) C# method invocation expression. (2) C# collection element initializer. For example, in the following collection initializer: new C() { 1, 2, 3 }, we will have 3 IInvocationOperation nodes, each of which will be a call to the corresponding Add method with either 1, 2, 3 as the argument. (3) VB method invocation expression. (4) VB collection element initializer. Similar to the C# example, New C() From {1, 2, 3} will have 3 IInvocationOperation nodes with 1, 2, and 3 as their arguments, respectively.

Properties

Arguments

Arguments of the invocation, excluding the instance argument. Arguments are in evaluation order.

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)
ConstrainedToType

Type parameter which runtime type will be used to resolve virtual invocation of the TargetMethod. Null if TargetMethod is resolved statically, or is an instance method.

Instance

'This' or 'Me' instance to be supplied to the method, or null if the method is static.

IsImplicit

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

(Inherited from IOperation)
IsVirtual

True if the invocation uses a virtual mechanism, and false otherwise.

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)
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)
TargetMethod

Method to be invoked.

Type

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

(Inherited from IOperation)

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.
