Answer 1

在App.razor中，添加以下代码行：

@inject NavigationManager NavigationManager
@implements IDisposable
@code {
protected override void OnInitialized() => NavigationManager.LocationChanged += OnLocationChanged;
private void OnLocationChanged(object? sender, EventArgs e)
{
//your code
Console.WriteLine("Location Changed...");
}
public void Dispose() => NavigationManager.LocationChanged -= OnLocationChanged;
}
