在Blazor中跨多个cshtml页面共享单个属性

public class SharedStateService
{
    private string _sharedProperty;

    public string SharedProperty
    {
        get => _sharedProperty;
        set => _sharedProperty = value;
    }
}

public void ConfigureServices(IServiceCollection services)
{
    services.AddSingleton<SharedStateService>();
    // 其他服务注册...
}

@page "/page1"
@inject SharedStateService SharedState

<h3>Page 1</h3>

<p>Shared Property Value: @SharedState.SharedProperty</p>

<button @onclick="UpdateProperty">Update Property</button>

@code {
    private void UpdateProperty()
    {
        SharedState.SharedProperty = "New Value";
    }
}

@page "/page2"
@inject SharedStateService SharedState

<h3>Page 2</h3>

<p>Shared Property Value: @SharedState.SharedProperty</p>

private void UpdateProperty()
{
    SharedState.SharedProperty = "New Value";
    StateHasChanged(); // 强制组件重新渲染
}
