DacpObjectData Structure

Defines a transport buffer for runtime object information.

Note

This API was originally designed for internal use in the runtime. Although it is now supported for 3rd party use, we recommend working with ICorDebug and ICorProfiler APIs when possible.

Syntax

struct DacpObjectData : ZeroInit<DacpObjectData>
{
    CLRDATA_ADDRESS MethodTable;
    DacpObjectType ObjectType;
    ULONG64 Size;
    CLRDATA_ADDRESS ElementTypeHandle;
    CorElementType ElementType;
    DWORD dwRank;
    ULONG64 dwNumComponents;
    ULONG64 dwComponentSize;
    CLRDATA_ADDRESS ArrayDataPtr;
    CLRDATA_ADDRESS ArrayBoundsPtr;
    CLRDATA_ADDRESS ArrayLowerBoundsPtr;

    CLRDATA_ADDRESS RCW;
    CLRDATA_ADDRESS CCW;
    
    HRESULT Request(ISOSDacInterface *sos, CLRDATA_ADDRESS addr)
    {
        return sos->GetObjectData(addr, this);
    }
};

Members

Member Description
MethodTable The address of the object's method table.
ObjectType A DacpObjectType enumeration value that identifies the object type.
Size The size of the object, in bytes.
ElementTypeHandle For arrays, the address of the element type handle.
ElementType For arrays, the CorElementType value for the element type.
dwRank For arrays, the number of dimensions.
dwNumComponents For arrays, the number of elements.
dwComponentSize For arrays, the size of each component, in bytes.
ArrayDataPtr For arrays, the address of the array data.
ArrayBoundsPtr For arrays, the address of the array bounds.
ArrayLowerBoundsPtr For arrays, the address of the array lower bounds.
RCW The address of the runtime callable wrapper associated with the object.
CCW The address of the COM callable wrapper associated with the object.
Request Populates the structure by calling ISOSDacInterface::GetObjectData.
