Why Am I Getting an 'Inconsistent Accessibility' Error When Passing Objects Between Forms?

Parameter Type Accessibility Mismatch Error

Passing objects between forms can sometimes lead to the "Inconsistent Accessibility" error. This error signifies a clash between the accessibility levels of the method and the parameter type it uses.

Error Details

This problem occurs when a private field or class is passed as an argument to a public method. For example, if a public method takes a private class as a parameter, this accessibility mismatch causes the error.

Solution

To fix this, ensure the parameter's accessibility level matches or exceeds the method's accessibility. Specifically, make the parameter type (e.g., the ACTInterface class) public or protected. Another solution is to change the parameter type to a more accessible interface or base class.

Maintaining consistent accessibility levels prevents the "Inconsistent Accessibility" error, enabling smooth object transfer between forms.
