c# – 为什么struct不能有无参数的构造函数

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,…
