public void GetTagLogRecord(int tagId, string keyword, string area) { var tag = _repositoryTagRecord.Get(tagId); OnlineGet(tag, keyword, area); }

if (cachedDelegate != null) { var args = cachedDelegate.Item1.Select(methodParameter => arguments[methodParameter.Name]).ToArray(); //此处args为object[]数组,调用下面的一句话始终报转换无效的错误, //调试时将args手动构造成 args = new object[] { 23, "PPAPI", "" };又没问题 !!!!!! //不知道是不是.NET的bug !!! var result = cachedDelegate.Item2(eventHandler, args); returnValue = result as IEnumerable; if (result != null && (returnValue == null || result is string)) returnValue = new[] { result }; return true; }
否则 cachedDelegate.Item2 始终报错 : 指定的转换无效 !!!!!

根本原因分析,入参字典 tagId 传入 int类型 9
在orchard反解析的过程中 会将数值类型转换为 long
private static object Convert(this JToken jToken) { if (jToken == null) { throw new ArgumentNullException(); } switch (jToken.Type) { case JTokenType.Array: var array = jToken as JArray; return array.Values().Select(Convert).ToArray(); case JTokenType.Object: var obj = jToken as JObject; return obj .Properties() .ToDictionary(property => property.Name, property => Convert(property.Value)); default: //这里会将9 转换为long类型 return jToken.ToObject<object>(); } }
解决办法 : 入参字典统一传没有类型歧义的 string !!!!!!
