Question

I have a function that is recursive in C# that i want to edit a global variable(i assume it is global due to the public before it) declared outside the function. For some reason that i do not know it cannot see the public variable within that specific function. It can see it in the first function in my code, but not in the second where i need to access it and change it to save a LOT of time opening a LOT of files…

Is there any reason why it wouldnt be accessable? and if so, how can i either get around it?

Thanks so much in advance!

public int[] timeInfo = new int[2];
   private void ListDirectory(TreeView treeView, string path) 
        {     
            treeView.Nodes.Clear();   
            var rootDirectoryInfo = new DirectoryInfo(path);    
            treeView.Nodes.Add(CreateDirectoryNode(rootDirectoryInfo)); 
        }

   private static TreeNode CreateDirectoryNode(DirectoryInfo directoryInfo) 

   {

       var directoryNode = new TreeNode(directoryInfo.Name);

       foreach (var directory in directoryInfo.GetDirectories())
            directoryNode.Nodes.Add(CreateDirectoryNode(directory));

       foreach (var file in directoryInfo.GetFiles())            
       {

           int check =0;

                   }

                   catch { }
                }

                TreeNode[] headerNodes = new TreeNode[row.Count];

                for (int i = 0; i < row.Count; i++)

                    headerNodes[i] = new TreeNode(row[i]);
                    if (check == 1)
                    {                       
                        headerNodes[i].BackColor = Color.Red;
                        headerNodes[i].ForeColor = Color.White;
                    }

                }
                directoryNode.Nodes.Add(new TreeNode(file.Name, headerNodes));
            }
            catch 
            {
                directoryNode.Nodes.Add(new TreeNode(file.Name));
            }
        }         
        return directoryNode; 
    }     

Answer 1

The second function is static, and the variable exists only in the context of an object.
