如何处理服务器端Asp.Net核心Web API中的自定义异常

throw new CustomException("自定义异常消息");

public class CustomExceptionFilter : IExceptionFilter
{
    public void OnException(ExceptionContext context)
    {
        if (context.Exception is CustomException)
        {
            // 处理自定义异常
            var customException = context.Exception as CustomException;
            // 返回自定义异常消息给客户端
            context.Result = new ObjectResult(customException.Message)
            {
                StatusCode = (int)HttpStatusCode.InternalServerError
            };
            // 标记异常已处理
            context.ExceptionHandled = true;
        }
    }
}

public void ConfigureServices(IServiceCollection services)
{
    services.AddMvc(options =>
    {
        options.Filters.Add<CustomExceptionFilter>();
    });
}
