第一步
将 KindEditor 的源文件添加到项目中，建议放到 /Scripts/kindeditor 目录中，其中只需要有 lang目录、plugis目录、themes目录和kindeditor-min.js文件即可。
第二步
在 /Views/Shared/EditorTemplates 目录中添加一个分部视图“kindeditor.cshtml”(文件名可任意)。代码如下：第三步
在需要应用编辑器的Model属性中设置 DataAnnotations，比如：第四步
在视图中使用 @Html.EditorFor(model => model.Content) 即可加载编辑器。附 KindEditorHandlerController 源码
