C#反射 - 获取未知领域的价值

Question

我试图使用反射来调用带有一些参数的方法但是我在使用正确的设置时遇到了一些困难.这就是我所做的.

// The method I am trying to call
// UnityGUI
// internal static float DoFloatField(EditorGUI.RecycledTextEditor editor, Rect position, Rect dragHotZone, int id, float value, string formatString, GUIStyle style, bool draggable)
// Called this way : EditorGUI.DoFloatField(EditorGUI.s_RecycledEditor, position, new Rect(0f, 0f, 0f, 0f), controlID, value, EditorGUI.kFloatFieldFormatString, style, false);

Type    editorGUIType = typeof(EditorGUI);
Type    RecycledTextEditorType = Assembly.GetAssembly(editorGUIType).GetType("UnityEditor.EditorGUI+RecycledTextEditor");
Type[]  argumentTypes = new Type[] { RecycledTextEditorType, typeof(Rect), typeof(Rect), typeof(int), typeof(float), typeof(string), typeof(GUIStyle), typeof(bool) };
MethodInfo doFloatFieldMethod = editorGUIType.GetMethod("DoFloatField", BindingFlags.NonPublic | BindingFlags.Static, null, argumentTypes, null);

// Here is the invoke part but I don't know how I can access to the s_RecycledEditor variable of type EditorGUI.RecycledTextEditor

FieldInfo fieldInfo = editorGUIType.GetField("s_RecycledEditor"); // This is null...
object o = fieldInfo.GetValue(null); // ... So the next part can't work.
object[] parameters = new object[]{ o, position2, position, controlID, controlID, "g7", style, true };
doFloatFieldMethod.Invoke(null, parameters);

我不知道如何获取s_RecycledEditor值以及下一个代码是否正常工作.我也不知道是否应该使用PropertyInfo或FieldInfo.

谢谢.

编辑:我忘了添加s_RecycledTextEditor的描述.

internal static EditorGUI.RecycledTextEditor s_RecycledEditor = new EditorGUI.RecycledTextEditor();

Type.GetField(string)只返回公共字段.我怀疑你想要:

FieldInfo fieldInfo = editorGUIType.GetField(
    "s_RecycledEditor", BindingFlags.NonPublic | BindingFlags.Static);
