reflection propertyinfo.getvalue compiles fine but gives erros in editor

Soo this is a very weird issue that I have no explanation for. So here is the code :

private void Update(){

private void GetAnimationCon(){
  var AnimPreviewInspector=Resources.FindObjectsOfTypeAll(typeof(Editor).Assembly.GetType("UnityEditor.AnimationClipEditor"));
 System.Reflection.FieldInfo[] fields = AnimPreviewInspector[0].GetType().GetFields(System.Reflection.BindingFlags.NonPublic  | System.Reflection.BindingFlags.Instance);
 var AnimPreview = new object();
 var AnimCon= new object();
 foreach (System.Reflection.FieldInfo f in fields){
   if( == "m_AvatarPreview")
       AnimPreview = f.GetValue(AnimPreviewInspector[0];
       System.Reflection.PropertyInfo[] props = AnimPreview.GetType().GetProperties(System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance);
       foreach(System.Reflection.PropertyInfo p in props){

          if(p.GetIndexParameters().Length==0&&p.Name == "Animator")
             AnimCon = p.GetValue(AnimPreview);


The above code compiles fine in Visual Studio, no complaints. It is done exactly like the examples shown in the C# docs. Now when I look at Unity it tries to tell me that there is no overload for method GetValue that takes 1 arguments. The line numbers are corresponding to wherever I am trying to get the value of a property. I’m like what the hell because it doesn’t compile in Visual Studio without an argument. Please help. Maybe its a bug and I can’t do anything about it? Below is a link to the documentation for the get value function. Also it doesn’t complain about me trying to get fields and that works just fine.

Well, read the documentation more carefully ^^

.NET Framework

Available since 4.5

Your target platform in visual studio is set to a higher level than what Unity actually supports. Unity basically supports up to .NET 3.5

So you have to pass the index array as well. However as far as i remember, if the property doesn’t have any index parameters you should be able to pass null.

AnimCon = p.GetValue(AnimPreview, null);

I still use the community version of visual studio 2015 and for me it recognises your code as error.

I just checked the docs, just to be sure:

This value should be null for
non-indexed properties.

So yes, passing null is correct.
