Yes you can have a list in struct but you cannot initialise it with a field initialiser and instead you must use the constructor.
是的，您可以在 struct 中有一个列表，但您不能使用字段初始化程序对其进行初始化，而必须使用构造函数。
struct MyStruct
{
public List<string> MyList;
public int MyInt;
public MyStruct(int myInt)
{
MyInt = myInt;
MyList = new List<string>();
}
}

struct can have a constructor and you can instantiate the list in the constructor.
struct 可以有一个构造函数，您可以在构造函数中实例化列表。

I am not an expert in C# but a structure is just a prototype of how your memory would look. You will have to declare a structure variable to be able to do "new list()" and assign it to a list variable.
我不是 C# 方面的专家，但结构只是您的内存外观的原型。您必须声明一个结构变量才能执行“new list()”并将其分配给列表变量。
something like struct test a; a.y = new list();
类似于 struct test a; ay = 新列表（）；
I have never programmed in C# so please convert my C syntax to C#.
我从未用 C# 编程，所以请将我的 C 语法转换为 C#。

You can do that - declare a constructor for the struct and create a list instance in the struct constructor. You can't use an initializer as you proposed in your code snippet.
您可以这样做 - 为结构声明一个构造函数并在结构构造函数中创建一个列表实例。您不能使用您在代码片段中建议的初始化程序。
