Net 6 nullable 不对所有类型发出警告
Net 6 nullable not giving warning for all types
使用 Net 6 <Nullable>enable</Nullable>
我有 class:
public class File {
public Int32 Id { get; set; }
public Byte[] Content { get; set; }
public DateTime Created { get; set; }
public Guid Key { get; set; }
public String Name { get; set; }
public FileType FileType { get; set; }
}
为什么我会收到警告
Non-nullable property '...' must contain a non-null value when exiting constructor. Consider declaring the property as nullable.
在所有属性中但不在:
Int32 Id
DateTime Created
Guid Key
可为空的引用类型只影响引用类型。值类型永远不能为空,因此无需检查或警告它们是否为空。
