title: C# Getting the size of the data returned from and SQL query
body: <p><strong>How can I get the size in bytes of the data returned from the database when executing a query?</strong>  The reason for this is to compare load on the database server using two different techniques.  We were running reports built from the same dataset which would load the entire dataset for every report.  Now we are caching the dataset and running reports from the cache.  We run reports per client, some datasets are significantly bigger than others, and I need some way to give a measurable metric for the database server load reduction.</p>
  
  <p>I have tried looking through DbConnection, DbDataReader and DbCommand for any existing functionality, but was unable to find it.  It would be great to measure the data throughput of a given connection or reader if possible, but any solutions are acceptable.  Is there perhaps a database server proxy I can use to measure it?</p>
  
  <p>The database is Oracle 10g.</p>
