在服务器端 Blazor 中验证页面参数

Question

I have a razor component page that accepts a parameter.

@page "/Customer/{CustomerId:int}"

Now I am checkking the method OnParametersSetAsync if the customerId exists. If it does not exists, I want to display/trigger 404 exception.

Is there any easy way to do this?

我认为您必须创建自己的 404 页面并使用NavigationManager将用户重定向到它

NavigationManager.NavigateTo("/404");
