c# - 如何声明 C# 记录类型？

Question

我读了on a blog C# 7 将以记录类型为特色

class studentInfo(string StudentFName, string StudentMName, string StudentLName);

但是当我尝试的时候，我得到了这些错误

CS0116 A namespace cannot directly contain members such as fields or methods
CS1022 Type or namespace definition, or end-of-file expected
CS1514 { expected

这应该如何工作？

更新:这是 C# 9 的一个特性 https://devblogs.microsoft.com/dotnet/welcome-to-c-9-0/

Answer 1

更新:

C# 9 now contains record types .

public record Person
{
    public string LastName { get; }
    public string FirstName { get; }

    public Person(string first, string last) => (FirstName, LastName) = (first, last);
}

旧答案:

记录类型(尚未)在 C# 中实现。请参阅官方 GitHub 存储库中的提案:
