Generic Type converting Puzzle

Question

i have method that its signature looks like

public object LoadCache(string cacheName,Type returnType)

and from this method another method is called which signature like this

 BBCacheProvider.BbCacheProvider.GetCache<T>(string cacheName);

is there any way to send returnType parameter as T in the method?

i believe that there is no way to do that! but there must be a way around it!

Sure its possible. http://msdn.microsoft.com/en-us/library/system.type.makegenerictype.aspx — asawyer, Oct 02 '13 at 13:16
the point here that we are using wcf and its impossible to pass a generic parameter throw the service. there for we must have a we to pass there type of the cache to load it from the provider. and it takes .and we do not know what T code be until run time. therefor am trying to pass the returntype as parameter and convert it to T :) by the way i do not think that Type.MakeGenericType might help. — MuhanadY, Oct 02 '13 at 13:27

If you can't make LoadCache generic, since it returns `object` anyway, can you just use `GetCache — mao47, Oct 02 '13 at 14:18
@mao47 actually you might be right, but the point is that T is a known type which will be set at run time from the client side! wcf makes it hard some times :) — MuhanadY, Oct 03 '13 at 05:26

i found a similar Solution here which i did change it as needed. so reflection is the hero.

public void ClientCacheLoadRerquest(Type tType, string key)
    {
        MethodInfo method = this.GetType().GetMethod("GetCache");
        MethodInfo closedMethod = method.MakeGenericMethod(tType);
        closedMethod.Invoke(this, new object[] { key });
    }
