SolrNet重复文件内容

我写了一个方法,扩展了SolrNet示例MVC应用程序中的一些功能。这很简单,在我的控制器中我添加了以下内容。

public string Index()         {             尝试             {                 var solr = ServiceLocator.Current.GetInstance>();                 String qs = Request.QueryString [“q”];                 var results = solr.Query(new SolrQueryByField(“asciiname”,qs));

            StringBuilder buffer = new StringBuilder();

            buffer.Append("<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n");
            buffer.Append("<kml xmlns=\"http://www.opengis.net/kml/2.2\"\n");
            buffer.Append(" xmlns:gx=\"http://www.google.com/kml/ext/2.2\">\n");
            buffer.Append("<Document>\n");
            buffer.Append("<name>\n");
            buffer.Append("Gazetteer\n");
            buffer.Append("</name>\n");
            buffer.Append("<description>\n");
            buffer.Append("World Places\n");
            buffer.Append("</description>\n");

            foreach (var i in results)
            {
                String lat = i.latitude.ToString();
                String lon = i.longitude.ToString();
                String name = i.asciiName.ToString();
                String coords = lon.ToString() + ","  + lat.ToString();

                name = name.Replace("&", "&amp;");
                name = name.Replace("<", "&lt;");
                name = name.Replace(">", "&gt;");

                buffer.Append("<Placemark>\n");
                buffer.Append("<name>\n");
                buffer.Append(name);
                buffer.Append("</name>\n");
                buffer.Append("<Point>\n");
                buffer.Append("<coordinates>\n");
                buffer.Append(coords);
                buffer.Append("</coordinates>\n");
                buffer.Append("</Point>\n");
                buffer.Append("</Placemark>\n");
            }
            buffer.Append("</Document>\n");
            buffer.Append("</kml>");
            Response.Write(buffer.ToString());

            Response.AddHeader("content-disposition", "attachment; filename=geonames.kml");
            Response.ContentType = "application/vnd.google-earth.kml+xml";
            Response.AppendHeader("Content-Encoding", "kml");

            return buffer.ToString();
        }
        catch (Exception)
        {
            return "ERROR";
        }
    }

生成KML文件,但内容从标记开始重复。这是否发生在var solr = ServiceLocator.Current.GetInstance&gt;();由于某些原因?我整天都在调试器中走过,似乎无法弄清楚为什么它会把整个事情写出来两次。它确实利用了foreach循环并通过它进行了正确迭代,但同样重复了整个文件的内容。

对此的任何帮助都会很棒! 亚当

呃......我完全忽视了我两次写缓冲区的事实!

Response.Write(buffer.ToString());

return buffer.ToString();
