TextCotent 在Kooboo.CMS.Content下面，在View中有使用到这个模型层。
TextContent继承了ContentBase,而ContentBase是由2个部分类组成的，一个是内容对象基类的子类，另一个是实现了持久化.那。。。我们该如何去理解呢，这里我用PS画一幅图大家就懂了。TextContent有3个构造函数，其中这2个构造函数都和基类（ContentBase）有关系。这3个构造函数分别如下：
/// <summary> /// Initializes a new instance of the <see cref="TextContent"/> class. /// </summary> /// <param name="dictionary">The dictionary.</param> public TextContent(IDictionary<string, object> dictionary) : base(dictionary) { } /// <summary> /// Initializes a new instance of the <see cref="TextContent"/> class. /// </summary> public TextContent() : base() { this.Id = string.Empty; } /// <summary> /// Initializes a new instance of the <see cref="TextContent"/> class. /// </summary> /// <param name="repository">The repository.</param> /// <param name="schemaName">Name of the schema.</param> /// <param name="folderName">Name of the folder.</param> public TextContent(string repository, string schemaName, string folderName) : base(repository, folderName) { this.Id = string.Empty; this.SchemaName = schemaName; }
大家也许会疑惑这个TextContent有什么用处，看看视图里面的ViewBag.XXX你就明白了，其实ViewBag.XXX得到的是一个弱类型，可以强制转换成TextContent，为什么我这么自信它可以转换为TextContent呢？因为其实在数据库里建立的这张表和TextContent是一一对应的，字段的名称都是相同的。
下面的是TextContent的全部代码，大家有兴趣的可以对比一下，都是一样的。
