Cant get default method from MemoryCache when set as a class property

Question

I am trying to avoid this:

 private ObjectCache cache = MemoryCache.Default

By creating a class:

public static class MemoryDefault
{
    public static MemoryCache Memory { get; set; }
}

When calling MemoryDefault.Memory.Default it does not exists, why?

Answer 1

Your property public static MemoryCache Memory { get; set; } is not initialized anywhere - so it will be always null..

It should rather be:

public static class MemoryDefault
{
    static MemoryDefault()
    {
         Memory = MemoryCache.Default;
    }

    public static MemoryCache Memory { get; private set; }
    //private set for preventing user to change that value
}

Other approach:

public static class MemoryDefault
{
    public static MemoryCache Memory { get { return MemoryCache.Default; } }
}
