  • Reference

Definition

Namespace:
Microsoft.VisualStudio.Debugger.Native.Cpp
Assembly:
Microsoft.VisualStudio.Debugger.Engine.dll
Package:
Microsoft.VisualStudio.Debugger.Engine v17.8.1101801

Compiles a given expression into native IL.

Location constraint: API must be called from an IDE component (component level > 100,000).

This API was introduced in Visual Studio 14 Update 2 (DkmApiVersion.VS14Update2).

Parameters

EvaluationFlags
DkmEvaluationFlags

[In] Flags which effect how an input expression should be parsed, compiled or displayed.

RuntimeInstance
DkmRuntimeInstance

[In] The DkmRuntimeInstance class represents an execution environment which is loaded into a DkmProcess and which contains code to be debugged.

TypeContext
DkmNativeCppType

[In,Optional] Optional type specifying the context in which to evaluate the expression. If non-null, the expression text may use the 'this' pointer to bind to an instance of this type.

IsThisPointerAvailable
Boolean

[In] True if a 'this' pointer is available to evaluate the expression. The generated IL will expect the 'this' pointer to be passed in as the first IL parameter, which will come before any named parameters. The type of the 'this' pointer should be be a pointer to the type indicated in the 'TypeContext' parameter. If no 'this' pointer is available, 'IsThisPointerAvailable' should be set to false. In this case, the resultant IL will not expect a 'this' pointer, but expression will be restricted to global and static members only. 'IsThisPointerAvailable' should always be false whenever 'TypeContext' is NULL.

InstructionAddress
DkmInstructionAddress

[In] The instruction address at which the resultant query will execute. This may affect the content of the returned inspection query in optimized code debugging scenarios.

Text
String

[In] The expression to compile.

Parameters
ReadOnlyCollection<DkmNativeCppNamedExpressionParameter>

[In,Optional] Optional list of named parameters available for use in the expression.

Error
DkmNativeCppCompilationError

[Out,Optional] If the expression failed to compile, specifies the reason for the failure.

Returns

DkmCompiledNativeCppExpression

[Out,Optional] Result of compiling the expression.
