C# 编程/关键字/unsafe

unsafe 关键字可以用来修饰一个过程或定义一个使用不安全代码的代码块。 如果代码使用了“地址运算符”(&) 或指针运算符(*)，则该代码是不安全的。

为了让编译器编译包含此关键字的代码，在使用 Microsoft C-Sharp 编译器时，必须使用 unsafe 选项。

class MyClass {
  public static void Main() {
    int x = 2;
    // example of unsafe to modify a code block
    unsafe {
      DoSomething(&x);
    }
  }

  // example of unsafe to modify a procedure
  unsafe static void DoSomething(int *msg) {
    Console.WriteLine(*msg);
  }
}
