在C#中,静态变量是与类型相关联的,而不是与类的实例相关联
public class MyClass
{
private static int myStaticVariable;
public static int MyStaticProperty
{
get { return myStaticVariable; }
set { myStaticVariable = value; }
}
}
public class MyClass
{
public static readonly int MyStaticVariable = 10;
}
public class MyClass
{
private static readonly MyClass instance;
static MyClass()
{
instance = new MyClass();
}
private MyClass() { }
}
ConcurrentQueue
、lock
等)来确保数据的一致性和安全性。public class MyClass
{
private static ConcurrentQueue<int> myConcurrentQueue = new ConcurrentQueue<int>();
public static void Enqueue(int value)
{
myConcurrentQueue.Enqueue(value);
}
public static bool TryDequeue(out int value)
{
return myConcurrentQueue.TryDequeue(out value);
}
}
public class MyClass
{
public static void UpdateStaticVariable(int newValue)
{
if (newValue >= 0)
{
myStaticVariable = newValue;
}
else
{
throw new ArgumentException("Value must be non-negative.");
}
}
}
通过遵循这些建议,可以在C#中有效地防范静态变量的安全风险。
