解决方法
我不能有一个显式的无参数构造函数,只有隐式的构造函数才能将所有成员初始化为默认值.
Although the CLR allows it,C# does not allow structs to have a default parameterless constructor. The reason is that,for a value type,compilers by default neither generate a default constructor,nor do they generate a call to the default constructor. So,even if you happened to define a default constructor,it will not be called and that will only confuse you. To avoid such problems,the C# compiler disallows definition of a default constructor by the user. And because it doesn’t generate a default constructor,you can’t initialize fields when defining them,…
