Since Size
is a struct, you can’t do that.
Instead, you need to assign a new Size
value to the property, like this:
this.MinimumSize = new Size(800, 600);
EDIT Your compiler is wrong; it’s confusing the Size
class with the Control.Size
property.
To work around this unjust error, you need to qualify the type with a namespace:
this.MinimumSize = new System.Drawing.Size(800, 600);
Or you just forgot using System.Drawing
.
