title: Didn't getting any response while fetching Ethereum event logs data (of specific event) using Nethereum in C# console application
body: <p>I am working in C# console application and need to read Ethereum event logs of specific event from Ethereum API. I have preferred Nethereum to do that task. But, Whenever i try to fetch the Event logs using API call then nothing is getting as output. Didn't get any expected data.</p>
  
  <p>I have a following parameters to get event logs:</p>
  
  <ol>
  <li>Ethereum API url</li>
  <li>Contract ABI address</li>
  <li>Contract address</li>
  <li>Event name</li>
  </ol>
  
  <p>following are the lines of code, which i am using to get event logs using Nethereum library in C# console application:</p>
  
  <pre><code>var web3 = new Nethereum.Web3.Web3(@UrlString);
  var contract = web3.Eth.GetContract(@abi, @contractAddress);
  var event = contract.GetEvent(@eventName);
  var filter = await event.CreateFilterAsync();
  var logs = await event.GetAllChanges&lt;MultipliedEvent&gt;(filter);
  </code></pre>
  
  <p>Didn't getting in "logs". Is anything missing by me?</p>
