如何在两个类之间共享静态ConcurrentDictionary

public static class SharedDictionary
{
    public static ConcurrentDictionary<string, object> Dictionary = new ConcurrentDictionary<string, object>();
}

public class MyClass1
{
    public void AddToSharedDictionary(string key, object value)
    {
        SharedDictionary.Dictionary.TryAdd(key, value);
    }
}

public class MyClass2
{
    public object GetValueFromSharedDictionary(string key)
    {
        object value;
        SharedDictionary.Dictionary.TryGetValue(key, out value);
        return value;
    }
}
