最近做项目要用文本编辑器，编辑器好多种，这里介绍KindEditor在asp[.NET][] mvc4中的使用方法。

一、准备工作：

1.下载KindEditor.去官网：[http://www.kindsoft.net/][http_www.kindsoft.net]

2.解压，拷贝到项目中（这里面有些例子，可以先删除掉在拷贝到项目中。）

二、使用步骤：

1.view页面

2.Controller中定义方法，就是js中 fileManagerJson和uploadJson的执行方法

public class KindEditorController : Controller
        {
            [HttpPost]
            public ActionResult UploadImage()
            {
                string savePath = "/Content/UploadImages/";
                string saveUrl = "/Content/UploadImages/";
                string fileTypes = "gif,jpg,jpeg,png,bmp";

3.最后在处理提交的Action上加 \[ValidateInput(false)\]特性，不然提交的报错：从客户端(“”)中检测到有潜在危险的 Request.Form 值
