推荐答案
我做了这个,希望能帮到你
I did this hope this helps
protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
{
JavaScriptRequest obj= DeserializeJavaScriptRequest(typeof(JavaScriptRequest), Resource1.test) as JavaScriptRequest;
MessageBox.Show(obj.appname +" | " + obj.taborder[0]);
}
public object DeserializeJavaScriptRequest(Type typedeserialize, string eValue)
{
Type t = typedeserialize;
// Get constructor info.
ConstructorInfo[] ci = t.GetConstructors();
object reflectOb = ci[0].Invoke(null);
MemoryStream confirm_ms = new MemoryStream(Encoding.UTF8.GetBytes(eValue));
DataContractJsonSerializer confirm_ser = new DataContractJsonSerializer(typedeserialize);
reflectOb = confirm_ser.ReadObject(confirm_ms);
confirm_ms.Close();
return reflectOb;
}
我做了一堂课
public class JavaScriptRequest
{
public string appname { get; set; }
public string[] taborder { get; set; }
}
