}
}

我收到这些错误:
'alt'的所有声明必须具有相同的修饰符.
后续属性声明必须具有相同的类型.属性'alt'必须是'string |类型 undefined',但这里有'string'类型.

如果有这个问题,我真诚地道歉.经过大约半小时的搜索,我似乎无法找到一个"最佳答案",而我遇到的大多数解决方案似乎都涉及JavaScript.虽然我并不完全反对JavaScript - 但HTML,CSS和PHP绝对是我更强大的技能组合.如果不使用JavaScript就无法做到这一点,我可能需要一些认真的宝贝谈话.这是我的问题:

我该怎么办?

据我所知,JSON.Net看起来已正确安装.

当在Globals.Asax中注释掉API路由时,JSON.Net实际上似乎有效.这不会引发任何错误:
