How to write a transaction to cover Moving a file and Inserting record in database?

Try to use .NET Transactional File Manager

This library allows you to wrap file system operations in transactions like this:

// Wrap a file copy and a database insert in the same transaction
TxFileManager fileMgr = new TxFileManager();
using (TransactionScope scope1 = new TransactionScope())
{
    // Copy a file
    fileMgr.Copy(srcFileName, destFileName);

    // Insert a database record
    dbMgr.ExecuteNonQuery(insertSql);

    scope1.Complete();
}
