boxing

[Khiem]

I try this

StructX x=func();
while(null!=(object)x)
{
   //do something
   x=anotherfunc(); 
} 

This fails, so I say boxing is a flaw. If not, then how can I check for a null struct please?
Thanks

Structs are Valutypes, use CLASSES !!


Another way would be using nullable Types.

MyStruct? xy = new MyStruct();
if (xy != null) {
	Console.WriteLine("Struct is created");
	MyStruct stest = xy.Value;
	stest.Val = 5;
	stest.Name = "Hallo";
	xy = new Nullable<MyStruct>(stest); 
}
	
public struct MyStruct {
	public int Val;
	public string Name;
}

As you see handling a simple struct to use it as nullable is a bit a strange task. If you need objects use referene types --> classes

Yeah, you are guaranteed that a value type will not be null by default. I would not start making nullable structs unless you have a very good reason for it. This is definitely not a language flaw.
