How to check if a picturebox is empty

[invader7]

I can't figure out how to check if a picturebox is empty, i tried

 if (picturebox.image != null) {}

but it dosn't work, is there a way to check it ? thanks

What do you mean it doesn't work? If you mean that it doesn't compile you are correct; there is not 'image' property, C# is case sensitive, the property name is 'Image', and it certainly does work to check if there is bot image assigned.

yes i know about case sensitive i wrote it correct to my program, it compiles but if there is an image it doesn't execute the code of if statement as it shoud.

Of course that is what happens, because if there is an image present "Image" will never be null, how could it? It is like assigning '10' to a variable and then wondering why it does not equal '9'. Well, it's because you set it to 10!

ok i just found a solution, i have a global variable and when i assign an image to picturebox i give my variable the value 1 and when needed i check if variable is 1, if yes dispose if not do nothing...

No... that is a bad solution. You don't need to reference count in C#.
