HttpResponseException 和 HttpException 之间有什么区别

HttpResponseException 和 HttpException 的区别

csharp
public HttpResponseMessage GetCustomer(int id)
{
    try
    {
        // 通过 id 获取客户信息
        Customer customer = GetCustomerById(id);
        // 如果客户不存在，则抛出 HttpResponseException
        if (customer == null)
        {
            throw new HttpResponseException(HttpStatusCode.NotFound);
        }
        // 返回客户信息的 HttpResponseMessage 对象
        return Request.CreateResponse(HttpStatusCode.OK, customer);
    }
    catch (Exception ex)
    {
        // 发生异常时，抛出 HttpResponseException
        throw new HttpResponseException(HttpStatusCode.InternalServerError);
    }
}

csharp
protected void Page_Load(object sender, EventArgs e)
{
    try
    {
        // 处理页面请求逻辑
    }
    catch (HttpException ex)
    {
        // 记录异常信息
        LogException(ex);
        // 根据异常类型返回不同的 HTTP 状态码
        if (ex.GetHttpCode() == 404)
        {
            Response.StatusCode = 404;
            Response.StatusDescription = "Not Found";
            Response.Write("The requested page was not found.");
        }
        else if (ex.GetHttpCode() == 500)
        {
            Response.StatusCode = 500;
            Response.StatusDescription = "Internal Server Error";
            Response.Write("An internal server error occurred.");
        }
        else
        {
            // 其他类型的异常处理
        }
        // 结束响应
        Response.End();
    }
}
