无法将类型“ T”隐式转换为“ TPropType”

Question

所以我有一个通用方法

  public virtual TPropType GetLocalized<TEntity, TPropType>(TEntity entity, Expression<Func<TEntity, TPropType>> keySelector,
        int? languageId = null, bool returnDefaultValue = true, bool ensureTwoPublishedLanguages = true)
        where TEntity : BaseEntity, ILocalizedEntity

我想将其转换为这样的内容：

    public TPropType GetLocalized<TEntity, TPropType, T>(TEntity entity, Expression<Func<TEntity, T>> keySelector,
        int? languageId = null, bool returnDefaultValue = true, bool ensureTwoPublishedLanguages = true)
        where TEntity : IEntity<T>, ILocalizedEntity

我可以打这个电话      GetLocalized（设置，x => x.Id，languageId，returnDefaultValue，ensureTwoPublishedLanguages）；

没有发生转换错误。

有人可以帮忙吗？
