Query for admin folder ID

Question

I am trying to query for the admin folder ID knowing only the name of the folder. For example, I have a folder named abc and it is in another folder named xyz. xyz is on the rootadmin folder and I have no trouble retreiving that folder ID when I query. I just can't seem to query for the id of abc.
I am using the plumtree.server api 5.0.1. Also, the documentation for the Plumtree API overview for .net incorrectly creates a multi-demitional array for objects as
Object[][] zzz = new Object[3][2]; This is for Java I beleive. To do what you need in C#, do this
Object[][] = new Object[3][];for(int i=0 ; i<3 ; i++){   zzz[i] = new object[2];}
This creates an array that can be passed to the API.
public int SearchFolderID(string folderName){IPTAdminCatalog ptAC = (IPTAdminCatalog)objSession.GetAdminCatalog();IPTAdminFolder rootFolder = ptAC.GetRootAdminFolder();//This will be returned if not found.intfolderID = -1;//This will limit the query results to just the property ID and the name.intnPropertiesToQuery = PT_PROPIDS.PT_PROPID_OBJECTID;Object[][] filter = newObject[3][];for(inti = 0; i<3;i++){      filter[i] = newObject[1];}filter[0][0] = PT_PROPIDS.PT_PROPID_NAME;filter[1][0] = PT_FILTEROPS.PT_FILTEROP_EQ;filter[2][0] = folderName;
IPTQueryResult ptResult = rootFolder.QuerySubfolders(nPropertiesToQuery,1,0,0,-1,filter);
if(ptResult.RowCount() >= 1){     for(inti=0;i<ptResult.RowCount();i++)    {          folderID += ptResult.ItemAsInt(0,PT_PROPIDS.PT_PROPID_OBJECTID);    }}
returnfolderID;}

Answer 1

I think that the code below has a bug. When it looks for a folder, it ONLY looks for folders that are a direct child of the root folder. The line:
IPTQueryResult ptResult = rootFolder.QuerySubfolders(nPropertiesToQuery,1,0,0,-1,filter);
will perform a query that returns all DIRECT CHILD subfolders of the ROOT folder that have the indicated name. In your example, this will work for the folder called "xyz", but will NOT work for the folder called "abc", since the abc folder is not in the root folder.
One option would be to do this search recursively. First, find the folder object called XYZ in the root folder. Then open that folder object. Then using THAT object, call QuerySubfolders on it, something like:
XYZFolder.QuerySubfolders(nPropertiesToQuery,1,0,0,-1,ABCfilter);
This will require some substantial changes to your code, I think, because you'll have to record the intermediate folder objects somewhere (i.e. in your current code you never open the XYZ folder, but this change would necessitate making calls on that object.) You'll probably want a function that takes in an AdminFolder object and a subfolder name, opens the subfolder, and returns it. Then you can call that function repeatedly, walking down the folder path.
P.S. There's another thing I don't understand about your code. Your code does "folderID += ...", but why would you want to increment the folderID? Shouldn't it read "folderID = ..."?
