C# 反射不调用方法
C# Reflection Not Calling Methods
我正在使用带反射的 Unity,我试图调用某个方法名称 Start,但我的代码没有调用它
这里是ModLoader.cs:
using UnityEngine;
using System.Collections;
using System.IO;
using System.Reflection;
using System.Collections.Generic;
public class ModLoader : MonoBehaviour {
List<MethodInfo> modMethods = new List<MethodInfo>();
// Use this for initialization
void Start () {
if (!Directory.Exists (Application.dataPath + "/../Mods")) {
Directory.CreateDirectory (Application.dataPath + "/../Mods");
}
foreach (var mod in Directory.GetFiles(Application.dataPath + "/../Mods", "*.dll")) {
var assembly = Assembly.LoadFile(mod);
foreach (var type in assembly.GetTypes()) {
foreach (var method in type.GetMethods()) {
modMethods.Add (method);
}
}
}
//Execute Start method in all mods
foreach (MethodInfo method in modMethods) {
print (method.Name);
if (method.Name == "Start" && method.GetParameters().Length == 0 && method.IsStatic) {
method.Invoke (null, new object[]{ });
}
}
}
// Update is called once per frame
void Update () {
//Execute Update method in all mods
foreach (MethodInfo method in modMethods) {
if (method.Name == "Update" && method.GetParameters().Length == 0 && method.IsStatic) {
method.Invoke (null, new object[]{ });
}
}
}
}
这是我的 mod(a .dll):
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using UnityEngine;
public class Class1 {
static void Start () {
Debug.Log("hello world");
foreach (GameObject go in GameObject.FindObjectsOfType<GameObject>()) {
if (go.GetComponent<MeshRenderer>()) {
go.GetComponent<MeshRenderer>().material.color = new Color(1f, 0f, 0f);
}
}
}
}
我在 "Mods" 文件夹中有来自构建的 dll,我知道我的脚本找到了它,我只是不知道为什么没有调用方法 ID。
如果您的 Start
方法中没有 public
关键字,它不会是 public,并且 GetMethods()
只会查找 public 默认方法。
要么使 Start
public,要么将 type.GetMethods()
更改为 type.GetMethods(BindingFlags.NonPublic | BindingFlags.Static)
。
您模块中的 Start 方法是私有的。默认情况下,反射与 public 方法一起使用。你需要做到 public:
public class Class1 {
public static void Start () {
Debug.Log("hello world");
foreach (GameObject go in GameObject.FindObjectsOfType<GameObject>()) {
if (go.GetComponent<MeshRenderer>()) {
go.GetComponent<MeshRenderer>().material.color = new Color(1f, 0f, 0f);
}
}
}
}
或为 GetMethods 方法指定 BindingFlags。您需要 BindingFlags.Static 和 BindingFlags.NonPublic
type.GetMethods(System.Reflection.BindingFlags.Static | System.Reflection.BindingFlags.NonPublic)
