Remove Record from a DataView

I have a DataView which has been populated with a list of files from a database table. I want to iterate through the DataView to see if there are any files there of a particular type, and if so, do something with that record, and then remove it from the DataView.

I've coded this as follows, but there's something missing - I can iterate over an object and then remove an object from it, since that will affect the iterator.

Any suggestions?

DataView dv = new DataView();
dv = ds.Tables[3].DefaultView;
dlFiles.DataSource = dv;
dlFiles.DataBind();
for (int j = 0; j < dv.ToTable().Rows.Count; j++) {
    if (dv.ToTable().Rows[j]["Fi开发者_开发知识库lePath"].ToString().ToLower().Contains(".pdf")) {
        //do something with this record and remove it from the dataview
    }
}

As a note, dlFiles is a DataList used to display the the items in the DataView. The files removed are displayed differently, and so should not be referenced when iterating through the DataList.

We can do like this,

  DataView dv = new DataView();
  dv = ds.Tables[3].DefaultView;      
  for (int j = 0; j < dv.ToTable().Rows.Count; j++)
  {
     if (dv.ToTable().Rows[j]["FilePath"].ToString().ToLower().Contains(".pdf"))
     {
         dv.Table.Rows.RemoveAt(j);
         dv.AcceptChanges();
     }
  }            

Well,use a new object such as datatable,copy the new data to this datatable,and bind your control.
