Methods

Evaluates a CIL instruction in the provided execution context, without increasing the program counter.

protected override CilDispatchResult DispatchInternal(CilExecutionContext context, CilInstruction instruction)

CilDispatchResult: A value indicating whether the dispatch was successful or caused an error.

Handles the case when the pushed value is incompatible with the type specified in the instruction.

protected virtual CilDispatchResult HandleFailedCast(CilExecutionContext context, TypeSignature originalType, TypeSignature targetType)

context CilExecutionContext: The context to evaluate the instruction in.
originalType TypeSignature: The type of the pushed object.
targetType TypeSignature: The type that the object was attempted to be converted to.

Handles the case when the pushed value is null.

protected virtual CilDispatchResult HandleNull(CilExecutionContext context, TypeSignature targetType)

Handles the case when the pushed value is compatible with the type specified in the instruction.

protected abstract CilDispatchResult HandleSuccessfulCast(CilExecutionContext context, ObjectHandle handle, TypeSignature targetType)
