C# 如何使用WCF服务在Silverlight数据网格中显示GIF图像？

我试图根据天气预报中天气WCF分配给当天的天气ID显示天气图标的图像。我正在datagrid中显示数据，并希望添加一个带有图标的新列。不幸的是，这些图标是我知道Silverlight不支持的GIF，所以如果有人能帮忙，那就太好了

 public partial class MainPage : UserControl
{

创建一个图像数组以及和之关联的ID

    private WeatherDescription[] weatherInformation;

    WeatherSoapClient weatherClient = new WeatherSoapClient();
    public MainPage()
    {
        InitializeComponent();

        weatherClient.GetCityForecastByZIPCompleted += new EventHandler<GetCityForecastByZIPCompletedEventArgs>(weatherClient_GetCityForecastByZIPCompleted);
        weatherClient.GetCityWeatherByZIPCompleted += new EventHandler<GetCityWeatherByZIPCompletedEventArgs>(weatherClient_GetCityWeatherByZIPCompleted);
        weatherClient.GetWeatherInformationCompleted += new EventHandler<GetWeatherInformationCompletedEventArgs>(weatherClient_GetWeatherInformationCompleted);
        weatherClient.GetWeatherInformationAsync();
    }

这就是我设置数组WCF调用结果的地方

    void weatherClient_GetWeatherInformationCompleted(object sender, GetWeatherInformationCompletedEventArgs e)
    {
        weatherInformation = e.Result;
    }

    void weatherClient_GetCityForecastByZIPCompleted(object sender, GetCityForecastByZIPCompletedEventArgs e)
    {
        this.dataGrid1.ItemsSource = e.Result.ForecastResult;
        for (int i = 0; i < e.Result.ForecastResult.Length; i++)
        {
            if (i == 0)
            {
                e.Result.ForecastResult[i].Temperatures.DaytimeHigh += "°F";
                e.Result.ForecastResult[i].ProbabilityOfPrecipiation.Daytime += "%";
            }
            else
            {
                e.Result.ForecastResult[i].Temperatures.DaytimeHigh += "°F";
                e.Result.ForecastResult[i].Temperatures.MorningLow += "°F";
                e.Result.ForecastResult[i].ProbabilityOfPrecipiation.Daytime += "%";
                e.Result.ForecastResult[i].ProbabilityOfPrecipiation.Nighttime += "%";
            } 
        }
    }

    void weatherClient_GetCityWeatherByZIPCompleted(object sender, GetCityWeatherByZIPCompletedEventArgs e)
    {
        this.textBlock1.Text = "City: " + e.Result.City + "\n";
        this.textBlock1.Text += "State: " + e.Result.State + "\n";
        this.textBlock1.Text += "Weather ID: " + e.Result.WeatherID + "\n";
        this.textBlock1.Text += "Weather Station: " + e.Result.WeatherStationCity + "\n";
        this.textBlock1.Text += "Temperature: " + e.Result.Temperature + "°F \n";
        this.textBlock1.Text += "Description: " + e.Result.Description + "\n";
        this.textBlock1.Text += "Pressure: " + e.Result.Pressure + "\n";
        this.textBlock1.Text += "Relative Humidity: " + e.Result.RelativeHumidity + "% \n";
    }

    private void button1_Click(object sender, RoutedEventArgs e)
    {
        weatherClient.GetCityWeatherByZIPAsync(inputZip.Text);
        weatherClient.GetCityForecastByZIPAsync(inputZip.Text);
    }
}
}

如果有帮助的话，这就是我对dataGrid的标记

<sdk:DataGrid AutoGenerateColumns="False" Height="310" Margin="12,131,407,0" Name="dataGrid1" VerticalAlignment="Top" AlternatingRowBackground="#00010000">
        <sdk:DataGrid.Columns>
            <sdk:DataGridTextColumn Header="Date" Binding="{Binding Date}" />
            <sdk:DataGridTextColumn Header="ID" Binding="{Binding WeatherID}" />
            <sdk:DataGridTextColumn Header="Description" Binding="{Binding Desciption}" />
            <sdk:DataGridTemplateColumn Header="Temperature">
                <sdk:DataGridTemplateColumn.CellTemplate>
                    <DataTemplate>
                        <StackPanel>
                            <TextBlock Text="{Binding Temperatures.DaytimeHigh}" Name="DaytimeHigh" />
                            <TextBlock Text="{Binding Temperatures.MorningLow}" Name="MorningLow"/>
                        </StackPanel>
                    </DataTemplate>
                </sdk:DataGridTemplateColumn.CellTemplate>
            </sdk:DataGridTemplateColumn>
            <sdk:DataGridTemplateColumn Header="Probability of Precipitation">
                <sdk:DataGridTemplateColumn.CellTemplate>
                    <DataTemplate>
                        <StackPanel>
                            <TextBlock Text="{Binding ProbabilityOfPrecipiation.Daytime}" Name="Daytime"/>
                            <TextBlock Text="{Binding ProbabilityOfPrecipiation.Nighttime}" Name="Nighttime"/>
                        </StackPanel>
                    </DataTemplate>
                </sdk:DataGridTemplateColumn.CellTemplate>
            </sdk:DataGridTemplateColumn>
        </sdk:DataGrid.Columns>
    </sdk:DataGrid>

如果你需要更多的信息，请告诉我。我希望有人能提供帮助。

Silverlight不支持GIF，因此您必须将其转换为jpg或png。我建议您只在服务器端执行一次

然后可以使用相对路径在模板列内的datagrid中显示图像

<Image x:Name="myImage" Source="../someImage.jpg" />

你的图像存储在哪里？您提到通过id引用它们。它们是否存储在数据库中？然后，您可以编写一个HTTP处理程序来加载图像或通过您的服务加载图像。

那么，您的问题是什么？是关于GIF还是你的实施我不知道怎么做。第一个问题是在引用ID时在datagrid中显示图像。然后如何将gif转换为jpg？我实际上刚刚写了一篇更好的文章来尝试并帮助解决这个问题，所以这是指向这个问题的链接。如果这不能回答你的问题，请告诉我。我感谢你的帮助！
