Unity adds a function case similar to editor extension to its script, the use of ContextMenu

Adding names to your objects is the most important thing to improve your development efficiency , The following is an example to illustrate , Next is my code

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class NameKeyValueString : MonoBehaviour
{
    

    public string NameKey = "null";

    public Sprite MySprite = null;
    // Start is called before the first frame update
    void Start()
    {
    
    
        if(this.GetComponent<Image>()!=null||this.GetComponent<SpriteRenderer>()!=null)
        {
    
            if(this.GetComponent<Image>()!=null)
            {
    
                if (GameResAssetBundle.GameResSprite.ContainsKey(NameKey))
                    this.GetComponent<Image>().sprite = GameResAssetBundle.GameResSprite[NameKey];
                else
                    Debug.Log(" Input NameKey Not included, please re-enter ");
            }
            else if(this.GetComponent<SpriteRenderer>()!=null)
            {
    
                if (GameResAssetBundle.GameResSprite.ContainsKey(NameKey))
                    this.GetComponent<SpriteRenderer>().sprite = GameResAssetBundle.GameResSprite[NameKey];
                else
                    Debug.Log(" Input NameKey Not included, please re-enter ");
            }
        }
    }

    [ContextMenu(" Automatically add a name to the script I write ")]
    public void AddNameKeyMyName()
    {
    
        string myname = null;

        if(this.GetComponent<Image>()!=null||this.GetComponent<SpriteRenderer>()!=null)
        {
    
            if(this.GetComponent<Image>()!=null)
            {
    
                myname = this.GetComponent<Image>().sprite.name;
            }
            else if(this.GetComponent<Image>()!=null)
            {
    
                myname = this.GetComponent<SpriteRenderer>().sprite.name;
            }
        }

        if(myname!=null)
        {
    
            NameKey = myname;
        }

    }

    [ContextMenu(" Automatically assign null to my original image ")]
    public void ClearPictureOrSpriteOrigionName()
    {
    
        string myname = null;

        if (this.GetComponent<Image>() != null || this.GetComponent<SpriteRenderer>() != null)
        {
    
            if (this.GetComponent<Image>() != null)
            {
    
                myname = this.GetComponent<Image>().sprite.name;
            }
            else if (this.GetComponent<Image>() != null)
            {
    
                myname = this.GetComponent<SpriteRenderer>().sprite.name;
            }
        }

        if (myname != null)
        {
    
            if (this.GetComponent<Image>() != null)
            {
    
                this.GetComponent<Image>().sprite = null;
            }
            else if (this.GetComponent<Image>() != null)
            {
    
                this.GetComponent<SpriteRenderer>().sprite = null;
            }
        }
    }
   
}
