示例1: BindSetIndex
public override DynamicMetaObject BindSetIndex(SetIndexBinder binder, DynamicMetaObject[] indexes, DynamicMetaObject value)
{
ComMethodDesc method;
var target = _callable.DispatchComObject;
var name = _callable.MemberName;
bool holdsNull = value.Value == null && value.HasValue;
if (target.TryGetPropertySetter(name, out method, value.LimitType, holdsNull) ||
target.TryGetPropertySetterExplicit(name, out method, value.LimitType, holdsNull))
{
List<ParameterExpression> temps = new List<ParameterExpression>();
List<Expression> initTemps = new List<Expression>();
bool[] isByRef = ComBinderHelpers.ProcessArgumentsForCom(method, ref indexes, temps, initTemps);
isByRef = isByRef.AddLast(false);
// Convert the value to the target type
DynamicMetaObject updatedValue = new DynamicMetaObject(value.CastOrConvertMethodArgument(
value.LimitType,
name,
"SetIndex",
temps,
initTemps), value.Restrictions);
var result = BindComInvoke(method, indexes.AddLast(updatedValue), binder.CallInfo, isByRef, temps, initTemps);
// Make sure to return the value; some languages need it.
return new DynamicMetaObject(
Expression.Block(result.Expression, Expression.Convert(value.Expression, typeof(object))),
result.Restrictions
);
}
return base.BindSetIndex(binder, indexes, value);
