Question

IndentedTextWriter tw = new IndentedTextWriter(internalTW, '    '); 

Object referenced by ‘tw’ is lost, but related resources are not disposed here ‘TW ‘ is a text writer where internalTW is a TextWriter

 OleDbConnection con = new OleDbConnection(conStr);  OleDbCommand cmd = new OleDbCommand(cmd1, con); 

object referenced by ‘cmd’ is lost, but related resources are not disposed here

Answer 1

Try

using (IndentedTextWriter tw = new IndentedTextWriter(internalTW, '    ')) {   // use it here } 

resp.

using (OleDbConnection con = new OleDbConnection(conStr)) using (OleDbCommand cmd = new OleDbCommand(cmd1, con)) {   // use it here } 

At the end of the using block, Dispose() is called on the objects and the resources should be freed…
