当我在 VS 中调试代码时,我返回的城市列表中包含 3 个对象以及属性。当我调用此端点时,我收到了 3 个空对象列表项的响应。
如何解决这个问题?
public class City
{
public string CityName;
public string AssociatedCities;
public string Province;
public int Status;
public City(string cityName, string associatedCities, string province, int status)
{
this.CityName = cityName;
this.AssociatedCities = associatedCities;
this.Province = province;
this.Status = status;
}
}

这就是我调用端点的方式
getCities() {
this.http.get<City[]>('/api/wizard/cities')
.subscribe(result => {
console.log(result);
this.cities = result;
}, error => console.error('Something went wrong : ' + error)); …Run Code Online (Sandbox Code Playgroud) 我使用Nebular创建登录表单。但Nebular的形式使用电子邮件验证。我想禁用电子邮件验证,因为我的网站使用username.

我正在尝试向 popover 添加按钮,但它似乎没有呈现。
是像我一样完成还是有更好的方法。
$('#myinput').popover({
trigger : "focus",
container : 'body',
placement : "bottom",
html : true,
title : "Choosy Popover",
content : `<input></input> Excellent <br><button type="submit">Why no display</button>`

.Net Framework和.Net Core有什么区别?
面试官问了这个问题,但我没有做到!
他还问:
为什么称为.Net Core?
是否有更简单或替代的方法来编写以下 C# 句子?
if (iValue >= 4 && iValue <= 10) {... other code ...}

我需要重复iValue两次吗?
我见过类似的结构,_ = ...some code... 但我不熟悉那个前导下划线?
