伙计们，我有以下循环，如果是一个列表，我必须再次循环，直到这里我还好，但是在另一个循环中我遇到了问题，因为我必须在“propretyinfo”中循环，我'必须循环这个 PropretyInfo 的对象并获取这个值，我在这里尝试了一个硬解析：

(List<ItemDeMescla>)objeto.GetValue(objeto, null)

但它抛出了一个异常，知道如何解析它并工作吗？

foreach (PropertyInfo objeto in processo.GetType().GetProperties())
{
    corpoEmail += CriarLinhaEmail(objeto.Name, Convert.ToString(objeto.GetValue(processo, null)), false);

    if (objeto.PropertyType.IsGenericType && (objeto.PropertyType.GetGenericTypeDefinition() == typeof(System.Collections.Generic.List<>)))
    {
        List<ItemDeMescla> itensMescla = (List<ItemDeMescla>)objeto.GetValue(objeto, null);
        foreach (ItemDeMescla item in itensMescla)
        {
            tabelasAux.Add(CriarTabelaInternaEmail<ItemDeMescla>(item, objeto.Name));
        }
    }
}

错误堆栈：

尝试获取对象的值，而不是 PropertyInfo：

(List<ItemDeMescla>)objeto.GetValue(processo, null)

尝试

objeto.GetValue(processo, null)

代替

objeto.GetValue(objeto, null)
