Wieso geht mein C# Code nicht mit Blazor?
Hallo, ich programmiere momentan eine WetterApp mit Blazor zur Übung und habe einen C# Code geschrieben, allerdings funktioniert da nichts. Kann mir wer helfen?
Hier mein C# Code
@if (weatherData != null)
{
<h4>@weatherData.Name</h4>
<p>Temperatur: @Math.Round(weatherData.Main.Temperature)°C</p>
<p>Luftfreuchtigkeit: @weatherData.Main.Humidity%</p>
<p>Windgeschwindigkeit: @weatherData.Wind.Speed km/h</p>
<p>Wetter: @weatherData.Weather[0].Main</p>
}
@code{
private string city;
private WeatherData weatherData;
private async Task CheckWeather()
{
string apiKey = "6958878b02398eb62a27936168c23c6";
string apiUrl = "https://api.openweathermap.org/data/2.5/weather?units=metric&q=";
using (HttpClient client = new HttpClient())
{
try
{
HttpResponseMessage response = await client.GetAsync($"{apiUrl}{city}&appid={apiKey}");
response.EnsureSuccessStatusCode();
string responseBody = await response.Content.ReadAsStringAsync();
weatherData = Newtonsoft.Json.JsonConvert.DeserializeObject<WeatherData>(responseBody);
}
catch (HttpRequestException e)
{
Console.WriteLine($"Fehler: {e.Message}");
}
}
}
public class WeatherData
{
public string Name{ get; set; }
public MainData Main { get; set; }
public WindData Wind { get; set; }
public WeatherCondition [] Weather { get; set; }
}
public class MainData
{
public double Temperature { get; set; }
public int Humidity { get; set; }
}
public class WindData
{
public double Speed { get; set; }
}
public class WeatherCondition
{
public string Main { get; set; }
}
}
Hier mein HTML Code:

Ich verstehe nicht weshalb mein ClickEvent nicht funktioniert und die Wetterdaten nicht angezeigt werden.
