C# 如何在RenderFragment Antd Blazor中触发@onclick

我正在使用ant design blazor（.net 5.0，antblazor 0.7.4）并尝试触发@onclick按钮render by RenderFragment:App.razor

   @inject NavigationManager NavigationManager

<Router AppAssembly="@typeof(Program).Assembly" PreferExactMatches="@true">
    <Found Context="routeData">
        <RouteView RouteData="@routeData" DefaultLayout="@typeof(BasicLayout)" />
    </Found>
    <NotFound>
        <LayoutView Layout="@typeof(BasicLayout)">
            <Result Status="404"
                    Title="404"
                    SubTitle="Sorry, the page you visited does not exist."
                    Extra="extra" />
        </LayoutView>
    </NotFound>
</Router>
<AntContainer />
@code
{ 
    private void NavigateToHome()
    {
        NavigationManager.NavigateTo("/");
    }
    RenderFragment extra =@<Button Type="primary" @onclick="NavigateToHome">Back Home</Button>;

}

@inject NavigationManager NavigationManager

如何解决这个问题？太多了
 
@inject NavigationManager NavigationManager
@inject NavigationManager NavigationManager

<Router AppAssembly="@typeof(Program).Assembly" PreferExactMatches="@true">
    <Found Context="routeData">
        <RouteView RouteData="@routeData" DefaultLayout="@typeof(BasicLayout)" />
    </Found>
    <NotFound>
        <LayoutView Layout="@typeof(BasicLayout)">
            <Result Status="404"
                    Title="404"
                    SubTitle="Sorry, the page you visited does not exist."
                    Extra="HomeButton(NavigateToHome)" />
        </LayoutView>
    </NotFound>
</Router>
<AntContainer />
@code
{ 
    private void NavigateToHome()
    {
        NavigationManager.NavigateTo("/");
    }
    RenderFragment HomeButton(Action clickAction) => @<Button Type="primary" @onclick="@clickAction">Back Home</Button>;

}

@代码
{ 
私有void NavigateToHome（）
{
NavigationManager.NavigateTo（“/”）；
}
RenderFragment Home按钮（Action clickAction）=>@返回主页；
}
