Cs1061 unity ошибка

AssetsScriptsGameContoller.cs(29,73): error CS1061: ‘GameObject[]’ does not contain a definition for ‘ToList’ and no accessible extension method ‘ToList’ accepting a first argument of type ‘GameObject[]’ could be found (are you missing a using directive or an assembly reference?) Полная ошибка.

Не могу понять в чем проблема, почему ему не нравиться ToList()?

I’m running into the quite simple aforementioned error. I thought I’d fix it quite quickly, but even after quite some searching, I can’t for the life of me figure out what the problem is. I Have the following Interface:

public interface ITemperatureEmitter
{
    float CurrentTemperatureAddon { get; }
}

I implement this in two other (empty for now) Interfaces:

public interface ITemperatureEmitterEnvironment : ITemperatureEmitter

public interface ITemperatureEmitterSphere : ITemperatureEmitter

Subsequently I use these three interfaces in the following class:

using System.Collections.Generic;
using UnityEngine;

public class TemperatureReceiver : MonoBehaviour, ITemperatureReceiver
{
    public float PerceivedTemperature;

    // Serialized for debug purposes
    [SerializeField] private List<ITemperatureEmitterSphere> temperatureEmitterSpheres;
    [SerializeField] private List<ITemperatureEmitterEnvironment> temperatureEmitterEnvironments;
    [SerializeField] private float environmentTemperature;
    [SerializeField] private float temperatureToModifyBy;
    [SerializeField] private float currentTemperatureAddon;
    [SerializeField] private float appliedTemperatureAddon;
    [SerializeField] private float totalTemperatureAddon;

    private void Update()
    {
        UpdatePerceivedTemperature();
    }

    private void OnTriggerEnter(Collider other)
    {
        if (other.GetComponent<ITemperatureEmitterSphere>() != null)
        {
            temperatureEmitterSpheres.Add(other.GetComponent<ITemperatureEmitterSphere>());
        }
        else if (other.GetComponent<ITemperatureEmitterEnvironment>() != null)
        {
            temperatureEmitterEnvironments.Add(other.GetComponent<ITemperatureEmitterEnvironment>());
        }
    }

    private void OnTriggerExit(Collider other)
    {
        if (other.GetComponent<ITemperatureEmitterSphere>() != null)
        {
            temperatureEmitterSpheres.Remove(other.GetComponent<ITemperatureEmitterSphere>());
        }
        else if (other.GetComponent<ITemperatureEmitterEnvironment>() != null)
        {
            temperatureEmitterEnvironments.Remove(other.GetComponent<ITemperatureEmitterEnvironment>());
        }
    }

    private void UpdatePerceivedTemperature()
    {
        ModifyPerceivedTemperature(temperatureEmitterSpheres);
        ModifyPerceivedTemperature(temperatureEmitterEnvironments);
    }

    private void ModifyPerceivedTemperature<ITemperatureEmitter>(List<ITemperatureEmitter> list)
    {
        if (list.Count > 0)
        {
            foreach (var item in list)
            {
                currentTemperatureAddon += item.CurrentTemperatureAddon;
            }
            currentTemperatureAddon = currentTemperatureAddon / list.Count;
            appliedTemperatureAddon = PerceivedTemperature;
            temperatureToModifyBy = currentTemperatureAddon = appliedTemperatureAddon;
            PerceivedTemperature += temperatureToModifyBy;
        }
    }
}

Now the item.CurrentTemperatureAddon in the ModifyPercievedTemperature method emits «error CS1061: Type ITemperatureEmitter does not contain a definition for CurrentTemperatureAddon and no extension method CurrentTemperatureAddon of type ITemperatureEmitter could be found. Are you missing an assembly reference?«

ITemperatureEmitter quite literally does contain a definition for CurrentTemperatureAddonm… Anyone has an idea what’s happening here?

I cannot explain why this is not working. So, I downloaded Git from the link. Is there an extra option after? After I downloaded and installed it I went to the package handler option. I then entered the link into the search by ULR option. I got the same Error saying Git was not Installed, but it is installed, so I do not know If I am missing a option. I went into the Package handler and installed the json file and it actually installed. It says that 2D Tilemap Extras has been installed. Now I keep getting a error though in the bottom. It is the

I am new to .NET visual studio, building windows Form Application.

I had the following error described below, when trying to build a solution. I am not sure if it has to do with something related to the file ‘SuperAdventure.SuperAdventure’ or a control that was not specified.

‘SuperAdventure.SuperAdventure’ does not contain a definition for ‘label5_Click‘ and no extension method ‘label5_Click’ accepting a first argument of type ‘SuperAdventure.SuperAdventure’ could be found (are you missing a using directive or an assembly reference?)

This is the error code with the error showing a red squiggly/line under the code in the marked line.

// lblExperience
// 
this.lblExperience.AutoSize = true;
this.lblExperience.Location = new System.Drawing.Point(110, 73);
this.lblExperience.Name = "lblExperience";
this.lblExperience.Size = new System.Drawing.Size(35, 13);
this.lblExperience.TabIndex = 6;
this.lblExperience.Text = "label7";
this.lblExperience.Click += new System.EventHandler(this.label5_Click); // <-- squiggly line here

and on the output it gives this:

Please let me know if I need to provided any more information.
PS: I am a beginner trying to learn some C# by building a RPG game as an exercise.
