Need to assign current logged in USER name to the people picker control in ASPX page

[jagsusa]

Hi All

I need to assign the current user to the people picker control in my custom ASPX page which I am planing to host in sharepoint (WSS) .

I was trying on these lines but without success.


System.Collections.ArrayList entityArrayList = new System.Collections.ArrayList();
PickerEntity entity = new PickerEntity();
userPicker = new PeopleEditor();
userPicker.MultiSelect = false;
entity.Key = SPContext.Current.Web.CurrentUser.LoginName;

entity= userPicker.ValidateEntity(entity);


entityArrayList.Add(entity.Key);
userPicker.UpdateEntities(entityArrayList);

It is throwing type casting exception.did tried with all the rules of the book but nothing worked!

Please let me know if you have any idea to fix this issue .


Thanks in advance
