title: Convert Datetime to date field to pass into Google BigQuery
body: <p>I am uploading data into BigQuery Cloud by my c# Application. I have column in BigQuery table 'ForDate' with datatype 'Date'.</p>
  
  <p>But in c# datatype is 'datetime'(As date datatype not supported in c#)
  I am getting Below error on uploading data to bigquery:
  {Invalid date: '2017-01-02T00:00:00' Field: ForDate; Value: 2017-01-02T00:00:00}</p>
  
  <p>What could be the workaround to upload date with date part only and ignore time part from it?</p>
