成员 XXX 不能用作方法或委托

Question

我在网上复制了这个教程，但是编译时出现如下2个错误：

"Non-invocable member 'Feature.choices' cannot be used like a method" 和 "The member `Feature.choices' cannot be used as method or delegate"

脚本中的最后一个 "choices" 有一条红色波浪线。任何想法可能是错误的？在此先感谢朋友们！

using System.Collections;
using System.Collections.Generic;

[ExecuteInEditMode]

public class FeatureManager : MonoBehaviour {

public List<Feature> features;
public int currFeature;

void OnEnable()
{
    LoadFeatures();
}
void OnDisable()
{
    SaveFeatures();
}
void LoadFeatures()
{
    features = new List<Feature>();
    features.Add(new Feature(("hair"), transform.FindChild("hair").GetComponent<SpriteRenderer>()));
}
void SaveFeatures()
{

}



}


[System.Serializable]
public class Feature
{
public string ID;
public int currIndex;
public Sprite[] choices;
public SpriteRenderer renderer;

public Feature(string id, SpriteRenderer rend)
{
    ID = id;
    renderer = rend;
    UpdateFeature();
        }

public void UpdateFeature()
{
    choices = Resources.LoadAll<Sprite>("Character/" + ID);

    if (choices == null || renderer == null)
        return;

    if (currIndex < 0)
        currIndex = choices.Length - 1;
    if (currIndex >= choices.Length)
        currIndex = 0;

    renderer.sprite = choices(currIndex);

}



}

Answer 1

改变这个

renderer.sprite = choices(currIndex);

对此：

renderer.sprite = choices[currIndex]; // use square brackets not parenthesis

成员 XXX 不能用作方法或委托
