示例1: CompileRegistrationIntoExpression
protected virtual Expression CompileRegistrationIntoExpression(IRegistration registration)
{
if (registration == null)
throw new ArgumentNullException("registration");
// Check if it is an InstanceRegistration<>
if (ReflectionHelper.IsInstanceOfGenericType(typeof(InstanceRegistration<>), registration) && _targetRegistration.CompileMode == CompileMode.Delegate)
{
var instance = registration.GetInstance();
return ConstantExpression.Constant(instance);
}
// Check if it is an IExpressionRegistration
var expReg = registration as IExpressionRegistration;
if (expReg != null)
{
// Check if the lifetime can be compiled
if (expReg.Lifetime is TransientLifetime)
{
// Keep visiting and try to inline the expression of the Registration found
// Recursive call until deepest nested ExpressionRegistration with TransientLifetime is found
// About to visit a child to the current - current becomes parent and registration/child to visit becomes current
var parent = _currentVisitedRegistration;
_currentVisitedRegistration = expReg;
// Visit - visit the body and return it so it is inlined within the original Expression<Func<IResolver, object>>
var expression = Visit(expReg.Expression.Body);
// Returned from visiting child - change it back again
_currentVisitedRegistration = parent;
return expression;
}
if (expReg.Lifetime is ContainerLifetime && _targetRegistration.CompileMode == CompileMode.Delegate)
{
var instance = expReg.GetInstance();
return ConstantExpression.Constant(instance);
}
}
// Returning null will make it keep visiting
return null;
}
