Client side Exception

This is an old revision of the document!

Usually the error dialog shows the root cause of an exception as first Exception, because it was the first occured Exception, e.g.

try
{
  throw new Exception("Root");
}
catch (Exception e)
{
  try
  {
    throw new Exception("Middle", e);
  }
  catch (Exception ex)
  {
    throw new Exception("Top, ex)
  }
}

The error dialog would show “Root” as message. If you want to show “Top” as message, simply use ClientException. The exception is a simple wrapper for another cause. If used, the last exception will be the first. In our example it would be “Top”.
