Update label location in C#?

I am creating a custom windows form and when trying to change the location of the label I get the error:Error 1 Non-invocable member ‘System.Windows.Forms.Control.Location’ cannot be used like a method.

Answer 1

The Location property is a struct and X is a property of that structure, and in this case you cannot set the value of X independently.

You need to do this:

lblMessage.Location = new Point(50, 50); // both X and Y will be set this way

or if you want to set only X value, set the Left property:

lblMessage.Left = 50;

You can only set properties of structs if you have a direct reference to that struct:

var loc = lblMessage.Location;
loc.X = 50;
lblMessage.Location = loc;
