Reflection examples for private methods and fields (C#)

Since the Oxide API page doesn't have any examples for C# and they're actually rather hard to find on these forums, here are some I found in plugins.

Get/Setting Private Fields examples

RemoveTool.cs

Code:

static FieldInfo buildingPrivlidges;/* get a pointer to the buildingPrivlidges field */
buildingPrivlidges = typeof(BasePlayer).GetField("buildingPrivlidges", (BindingFlags.Public | BindingFlags.Static | BindingFlags.Instance | BindingFlags.NonPublic));/* get building privileges for the specified player */
List<BuildingPrivlidge> playerpriv = buildingPrivlidges.GetValue(player) as List<BuildingPrivlidge>;

Clans.cs

Code:

/* get pointer to the _displayName field */
FieldInfo displayName = typeof(BasePlayer).GetField("_displayName", (BindingFlags.Instance | BindingFlags.NonPublic));/* set the players new name */
displayName.SetValue(player, stripTag(player.displayName, clan));

Calling Private Method example

Rust.IO

Code:

/* get a pointer to the UpdateServerInformation method */
MethodInfo method = typeof(ServerMgr).GetMethod("UpdateServerInformation", BindingFlags.Instance | BindingFlags.NonPublic | BindingFlags.InvokeMethod);/* call the private method */
method.Invoke(SingletonComponent<ServerMgr>.get_Instance(), new object[0]);

CopyPaste.cs

Code:

/* get a pointer to the Clear method */
private MethodInfo inventoryClear = typeof(ItemContainer).GetMethod("Clear", BindingFlags.NonPublic | BindingFlags.Instance);/* call the private method */
inventoryClear.Invoke(box.inventory, null);

So some thing to note are for methods the pointer is defined as MethodInfo and for fields it's FieldInfo, also note the binding flags, one I didn't use in the examples is BindingFlags.Static but i've seen it used in code. The rest are used quite a bit. I hope that Wulf can update the API page with these or other examples as that'd save a lot of time for plugin developers who want to tap into the private stuff.

 

It's your barbecue I just come for the food
