我想在航空公司名称下方显示航空公司图像。我已将航空公司图像的路径存储在 XML 文件中。我将如何使用 LINQ 在查询中显示图像？

到目前为止，这是我的代码：

var query = from f in XElement.Load(MapPath("flightdata2.xml")).Elements("flight")
                    select new
                    {                        
                        Airline = (string)f.Element("airline"),
                        DepartureAirportSymbol = (string)f.Element("departureAirportSymbol"),
                        DepartTime = (string)f.Element("departureTime"),
                        DestinationAirportSymbol = (string)f.Element("destinationAirportSymbol"),
                        ArrivalTime = (string)f.Element("arrivalTime"),
                        Stops = (int)f.Element("numberOfStops"),
                        Duration = (string)f.Element("duration"),
                        Cabin = (string)f.Element("class"),
                        Price = "$" + (Int32)f.Element("price")
                    };

    this.GridView1.DataSource = query;
    this.GridView1.DataBind();

I want to display an airline image underneath an airline name. I have stored paths in my XML file for the airlineImage. How would I go about displaying the image in my query using LINQ?

Here's my code so far:

var query = from f in XElement.Load(MapPath("flightdata2.xml")).Elements("flight")
                    select new
                    {                        
                        Airline = (string)f.Element("airline"),
                        DepartureAirportSymbol = (string)f.Element("departureAirportSymbol"),
                        DepartTime = (string)f.Element("departureTime"),
                        DestinationAirportSymbol = (string)f.Element("destinationAirportSymbol"),
                        ArrivalTime = (string)f.Element("arrivalTime"),
                        Stops = (int)f.Element("numberOfStops"),
                        Duration = (string)f.Element("duration"),
                        Cabin = (string)f.Element("class"),
                        Price = "$" + (Int32)f.Element("price")
                    };

    this.GridView1.DataSource = query;
    this.GridView1.DataBind();

试试这个：

select new
{
   Duration = (string)f.Element("duration"),
   Cabin = (string)f.Element("class"),
   Price = "$" + (Int32)f.Element("price")
   ImagePath = (string)f.Element("airlineImage")
};


<asp:GridView runat="server" ID="GridView1" AutoGenerateColumns="false">
   <Columns>
      <asp:ImageField DataImageUrlField="ImagePath" 
                      DataImageUrlFormatString="~/Content/Images/{0}" />
   </Columns>
</asp:GridView>

更新
1. 您必须将 GridView 中的路径 ~/Content/Images/{0} 替换为存储图像的位置。
2. 设置 AutoGenerateColumns="false"，以便您的网格将仅包含您已定义的列。

Try this:

select new
{
   Duration = (string)f.Element("duration"),
   Cabin = (string)f.Element("class"),
   Price = "$" + (Int32)f.Element("price")
   ImagePath = (string)f.Element("airlineImage")
};


<asp:GridView runat="server" ID="GridView1" AutoGenerateColumns="false">
   <Columns>
      <asp:ImageField DataImageUrlField="ImagePath" 
                      DataImageUrlFormatString="~/Content/Images/{0}" />
   </Columns>
</asp:GridView>

UPDATE
1. You have to replace path ~/Content/Images/{0} in GridView to where you store your images.
2. Set AutoGenerateColumns="false" so your grid will only contains colums that you have defined.
