The IDE says that the error is for two reasons:

  1. checked is a keyword that is used to explicitly enable overflow checking when performing arithmetic operations and conversions with integer data. see the documentation . Therefore, it is already impossible to use it in if and there will be an error.

  2. Checkbox has a Checked property. I note that the property is written with a capital letter.

    That it must be checked. Naturally, it is necessary to specify an object at the beginning, and then a property of the object through a dot. You now have it if it were not a keyword, then it does not apply to anything. And you need to write at least checkBox1.Checked
