the current situation can result in really ugly code though.

dataobject.someProperty = formObject.recomputeValue(dataobject.someProperty, otherValue1, otherValue2, ...);

vs

Why do you think that the code is ugly? If the method returns a value, the return value is a good place to put it.

Guffa wrote:

That should actually be:

int temp;<br />
formObject.recomputeValue(ref temp, otherValue1, otherValue2, ...);<br />
dataobject.someProperty = temp;

If that would be allowed, it would be implemented exactly as the code with the temporary variable, with the only exception that the the temporary variable doesn't have a name.

Allowing properties as out parameters would only serve to hide what's actually going on. In a language like VB that might be desired, but hardly in C#.

Shorter code is not always better code.

Most important of all is No authentication Required option. This option should be selected otherwise even if all of the above check boxes are selected, the exception will not go away.
