Using out with external plugin (C#)

Code:

// plugin TDC_Core
private void Give(BasePlayer player, string item, int amount, ItemContainer container, out bool success, out String itemdesc)
...
    success = true;
    itemdesc = "123";
    return;// in another method, other plugin TDC_Admin
[PluginReference("TDC_Core")] Plugin PTDCCore;
....
    bool success;
    String itemdesc;
    PTDCCore.Call("Give", (BasePlayer)TargetPlayer, Item, Amount, (ItemContainer)((BasePlayer)TargetPlayer).inventory.containerMain, out success, out itemdesc);

Error:
error CS1615: Argument `#6' does not require `out' modifier. Consider removing `out' modifier

What I'm doing wrong?

 

Yes, but it's not working, if out is not set. I want to receive these 2 variables and use them
[DOUBLEPOST=1432292762,1432228314][/DOUBLEPOST]Tried to use a struct for this. Failed.

Core Plugin

Code:

        struct SGiveItem {
            public bool Success { get; set; }
            public string ItemDescription { get; set; }
        }
        private SGiveItem GiveItem(BasePlayer player, string itemname, int amount, ItemContainer container) {
            ...
            return new SGiveItem(){Success=true,ItemDescription=description};
        }

Admin Plugin

Code:

        struct SGiveItem {
            public bool Success { get; set; }
            public string ItemDescription { get; set; }
        }
        [ChatCommand("admin")]
        void help(BasePlayer player, string command, string[] args) {
             ...
             SGiveItem GiveItemResponse;
             GiveItemResponse = (SGiveItem)PTDCCore.Call("GiveItem", (BasePlayer)TargetPlayer, Item, Amount, (ItemContainer)((BasePlayer)TargetPlayer).inventory.containerMain);
