c# - C# 自动实现的静态属性是线程安全的吗？

Question

我想知道 C# 是否自动实现了属性，例如 public static T Prop { get;放; }，是否线程安全。谢谢!

Answer 1

C# 规范的第 10.7.4 节指出:

When a property is specified as an automatically implemented property, a hidden backing field is automatically available for the property, and the accessors are implemented to read from and write to that backing field. The following example:

public class Point {
  public int X { get; set; } // automatically implemented
  public int Y { get; set; } // automatically implemented
}

is equivalent to the following declaration:

public class Point {
  private int x;
  private int y;
  public int X { get { return x; } set { x = value; } }
  public int Y { get { return y; } set { y = value; } }
}

这是我们的 promise ，也是您得到的。 auto properties 的意义在于做最基本、最简单、最廉价的事情；如果你想做一些更奇特的事情，那么你应该写一个“真正的”属性。
