DataFlowAnalysis Class

Definition

Namespace:

Microsoft.CodeAnalysis

Assembly:

Microsoft.CodeAnalysis.dll

Package:

Microsoft.CodeAnalysis.Common v4.9.2

Source:

DataFlowAnalysis.cs

Provides information about how data flows into and out of a region. This information is returned from a call to Microsoft.CodeAnalysis.SemanticModel.AnalyzeDataFlow(Microsoft.CodeAnalysis.SyntaxNode,Microsoft.CodeAnalysis.SyntaxNode), or one of its language-specific overloads, where you pass the first and last statements of the region as parameters. "Inside" means those statements or ones between them. "Outside" are any other statements of the same method.

Properties

AlwaysAssigned	The set of local variables for which a value is always assigned inside a region.
Captured	The set of the local variables that have been referenced in anonymous functions and therefore must be moved to a field of a frame class.
CapturedInside	The set of variables that are captured inside a region.
CapturedOutside	The set of variables that are captured outside a region.
DataFlowsIn	The set of local variables which are assigned a value outside a region that may be used inside the region.
DataFlowsOut	The set of local variables which are assigned a value inside a region that may be used outside the region.
DefinitelyAssignedOnEntry	The set of local variables which are definitely assigned a value when a region is entered.
DefinitelyAssignedOnExit	The set of local variables which are definitely assigned a value when a region is exited.
ReadInside	The set of local variables that are read inside a region.
ReadOutside	The set of the local variables that are read outside a region.
Succeeded	Returns true if and only if analysis was successful. Analysis can fail if the region does not properly span a single expression, a single statement, or a contiguous series of statements within the enclosing block.
UnsafeAddressTaken	The set of non-constant local variables and parameters that have had their address (or the address of one of their fields) taken.
UsedLocalFunctions	The set of local functions that are used.
VariablesDeclared	The set of local variables that are declared within a region. Note that the region must be bounded by a method's body or a field's initializer, so parameter symbols are never included in the result.
WrittenInside	The set of local variables that are written inside a region.
WrittenOutside	The set of local variables that are written outside a region.
