我需要在 Windows 10 UWP 应用程序的 XAML 页面上加载数据。为此,我编写了代码以在异步任务函数中调用 Web 服务,并在页面构造函数中调用它。你能告诉最好的方法吗?以下是我的代码。
public sealed partial class MyDownloads : Page
{
string result;
public MyDownloads()
{
this.InitializeComponent();
GetDownloads().Wait();
string jsonstring = result;
//code for binding follows
}
private async Task GetDownloads()
{
JsonObject jsonObject = new JsonObject
{
{"StudentID", JsonValue.CreateStringValue(user.Student_Id.ToString()) },
};
string ServiceURI = "http://m.xxx.com/xxxx.svc/GetDownloadedNotes";
HttpClient httpClient = new HttpClient();
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, ServiceURI);
request.Content = new StringContent(jsonObject.ToString(), Encoding.UTF8, "application/json");
HttpResponseMessage response = await httpClient.SendAsync(request);
string returnString = await response.Content.ReadAsStringAsync();
result = returnString;
}
}
