Class is inaccessible due to its protection level

Question

I have three classes  all are part of the same namespace  here are the basics of the three classes     FBlock cs namespace StubGenerator PropGenerator       class FBlock   IDesignRegionInserts  IFormRegionInserts  IAPIRegionInserts   IConfigurationInserts  ISoapProxyClientInserts  ISoapProxyServiceInserts               private List lt Property gt  pProperties          private List lt Method gt  pMethods          public FBlock string aFBlockName                         pProperties   new List lt Property gt                 pMethods   new List lt Method gt                        public Property AddProperty string aName                        Property loProp   new Property this  aName  pProperties Count               pProperties Add loProp               return loProp                       public Method AddMethod string aName                          Method loMeth   new Method this  aName                pMethods Add loMeth                return loMeth                        Method cs  namespace StubGenerator PropGenerator         class Method   IPropertyName                 private List lt StubGenerator PropGenerator PropertyAttribute gt  pPropertyAttributes           private string pName           private string pFBlockName            public Method FBlock aFBlock string aName                          pPropertyAttributes   new List lt PropertyAttribute gt                  pName   aName               pFBlockName   aFBlock Name                            Property cs  namespace StubGenerator PropGenerator        class Property   StubGenerator PropGenerator IPropertyName  StubGenerator PropGenerator IDesignRegionInserts  StubGenerator PropGenerator IFormRegionInserts  IAPIRegionInserts  IConfigurationInserts  ISoapProxyClientInserts  ISoapProxyServiceInserts               private string pName          private string pExpandedName          private string pFBlockInitials           private Group pPropertyGroup          private FlowLayoutPanel pGroupFlowPanel          private Button pUpdateButton          private CheckBox pShowProperty             private string pFBlockName             public Property FBlock aFBlock  string aName  int aIndex                          pPropertyAttributes   new List lt PropertyAttribute gt                  pFBlockName   aFBlock FBlockName                ExpandName                 GetInitials                  pShowProperty   new CheckBox this  10   aIndex   1    20  aIndex                pPropertyGroup   new Group this                pGroupFlowPanel   new FlowLayoutPanel this                 pUpdateButton   new Button this  10  18  aIndex                         I m getting the following errors      StubGenerator PropGenerator Method  is inaccessible due to its protection level    which refers to the following line in the FBlock cs file  private List lt Method gt  pMethods    and      StubGenerator PropGenerator Method  is inaccessible due to its protection level    which refers to the following line in the FBlock cs file   public Method AddMethod string aName    and     Inconsistent accessibility  return type  StubGenerator PropGenerator Method  is less accessible than method  StubGenerator PropGenerator FBlock AddMethod string      which refers to the following line in the FBlock cs file   public Method AddMethod string aName    making the class Method public does not resolve the errors   I can t figure out why I don t get the errors when calling the Property class  And I don t understand why making the Method class public doesn t fix the problem   Any ideas   Edited to ask  could there be some setting on the file that causes this

It may also be the case that the library containing the class in question is not properly signed with a strong name

The code you posted does not produce the error messages you quoted  You should provide a  small  example that actually exhibits the problem

First thing  try a full rebuild  Clean and build  or just use rebuild   Every once in a long while that resolves bizarre build issues for me   Next  comment out the rest of the code that is not in your example you have posted  Compile  Does that work    If so  start adding segments back until one breaks it   If not  make all the classes public and try again   If that still fails  maybe try putting the trimmed down classes in the same file and rebuilding  At that point  there would be absolutely no reason for access issues  If that still fails  take up carpentry

I m guessing public Method AddMethod string aName  is defined on a public interface that FBlock implements  Consumers of that interface are not guaranteed to have access to Method

Try adding the below code to the class that you want to use   Serializable    public partial class Class

User · Answer

your class should be public public class FBlock   IDesignRegionInserts  IFormRegionInserts  IAPIRegionInserts   IConfigurationInserts  ISoapProxyClientInserts  ISoapProxyServiceInserts

User · Answer

All your classes are internal by default  Marking public did not do the trick   Are you sure you do not have two classes named Method  and perhaps are including the wrong Method class

There was a project that used linked files   I needed to add the method cs file to that project as a linked file as well  since the FBlock cs file was there   I ve never heard of linked files before  I didn t even know that was possible
