In C#, if I am returning a Point and cannot find the coordinate what should I return? -

-

First of all, this is not an exception because it is part of the normal flow of operations. I tried to return a blank object, but it was not allowed. I can return negative coordinates with a point point, but it looks like a hack. For example, if I return (-1, -1) instead of checking for a negative number, maybe some use of my library could directly check the similarity with -1 which will then break if in my internal implementation Change

You return a blank number by changing your return type to point You can. In this way you can also return the null .

Otherwise you can create a static point example anywhere with (& minus; 1, and minus; 1) and always compare it with PointUtils.InvalidPoint probably < Code> px == -1 & amp; Amp; P.y == -1 .

c# - TypeConverter in propertygrid only converts from string, not to -

-
When the property grid is reached, only the conversion mechanism (often called) is called "Foo!" Returns the property string in the grid when I click to edit I get an exception Type.oo. Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends.
