title: how to read local excel file using webapi?
body: <pre><code>public class ExcelParserController : ApiController
  {
      [HttpGet]
      public IEnumerable&lt;string&gt; Get(string templatePath)
      {
          ExcelParser excelParser = new ExcelParser();
          return excelParser.Parse(templatePath);
      }
  }
  </code></pre>
  <p>This is my first idea. But I cannot know how to read local excel file from server. <code>templatePath</code> is like <code>&quot;C:\1.xlsx&quot;</code>. How to open local file by using webapi?</p>
