将Type作为参数传递给模板函数

2024-05-03 • 问答

我正在重构代码，我想替换这些调用：

            OnClickEv onClickPr = GetScriptPr<OnClickEv>(controlProps);
            if (onClickPr != null && onClickPr.Value != null)
                _script.Add(onClickPr.Value.ToString());

            OnDblClickEv onDblClickPr = GetScriptPr<OnDblClickEv>(controlProps);
            if (onDblClickPr != null && onDblClickPr.Value != null)
                _script.Add(onDblClickPr.Value.ToString());

            OnKeyDownEv onKeyDownEv = GetScriptPr<OnKeyDownEv>(controlProps);
            if (onKeyDownEv != null && onKeyDownEv.Value != null)
                _script.Add(onKeyDownEv.Value.ToString());

具有单一功能，我只需传递应该处理的类或类型：

CreateSimplePropWithParam(controlProps,new List<Type>()
            {
                typeof(OnClivkEv),typeof(OnDblClickEv),typeof(OnKeyDownEv)
            });

模板功能：

private T GetScriptPr<T>(List<ScriptPr> properties) where T : ScriptPr
        {
            var pr = properties.Where(x => x.GetType() == typeof(T)).FirstOrDefault();

            return (T)pr;
        }

但是如何将Type参数传递给Template？

private void CreateSimplePropWithParam(List<ScriptPr> controlProps,DesignerPlatform designerPlatform,object param,List<Type> propsList)
        {
            foreach (Type type in propsList)
            {
                T prop = (ScriptPr)GetScriptPr<T>(controlProps); <<< what to do with T?


                if (prop != null && prop.Value != null)
                {...
}}}

static readonly MethodInfo s_GetScriptPr = typeof(Whatever) .GetMethod("GetScriptPr",BindingFlags.Instance | BindingFlags.NonPublic); ... object result = s_GetScriptPr.MakeGenericMethod(type).Invoke(targetInstance,new object[] { controlProps });
