Accessibility of a program member is bypassed through reflection.
It is considered to be a bad practice to bypass and not consider the accessibility of a method or a field. So one should never change or ignore accessibility of classes, methods or fields since it could lead to security issues. This checker warns if this is achieved through reflection.

using System.Reflection;
namespace ReflectionExample

public class ReflectionCode
{
public static void ByPassingAccessibility()
{
Type classToModify = Type.GetType("ClassToModify");
BindingFlags newAttribute = BindingFlags.NonPublic;
MethodInfo methodToSearch = dynClass.GetMethod("mymethod", newAttribute); // "Reflection Bypasses Member Accessibility (C#)" warning issued here
// - newAttribute is set to BindingFlags.NonPublic, so this call will also retrieve non-visible progam members
object result = methodToSearch.Invoke(classToModify, null);
}
}
}
Don't change or bypass the accessibility level of program members. Only use reflective method calls that take into account the visibility of the target member.
The following configuration file parameters affect checks for this warning class.
