从官网下载kindeditor4.1.7：

1、将文件夹复制到VS2010

2、将文件　LitJSON.dll　复制到web\bin目录下，并添加引用

3、修改file_manager_json.ashx文件中的图片保存目录

 String rootUrl = aspxUrl + "Uploads/";

4、修改upload_json.ashx文件中的图片保存目录

//文件保存目录路径
        String savePath = "Uploads/";

  //文件保存目录URL
        String saveUrl = aspxUrl + "Uploads/";

5、修改kindeditor417\plugins\image\images.js文件（原文件为PHP的配置）

uploadJson = K.undef(self.uploadJson, self.basePath + 'asp.net/upload_json.ashx'),

6、页面：

            allowFileManager: true,
            syncType: "auto",
            afterCreate: function () {
                var self = this;
                KindEditor.ctrl(document, 13, function () {
                    self.sync();
                    KindEditor('form[name=example]')[0].submit();
                });
                KindEditor.ctrl(self.edit.doc, 13, function () {
                    self.sync();
                    KindEditor('form[name=example]')[0].submit();
                });
            },
            afterChange: function () { this.sync(); },
            afterBlur: function () { editor1.sync(); }
        });
 
        prettyPrint();
    }); </script>

</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">

</asp:Content>
<asp:Content ID="Content3" ContentPlaceHolderID="ContentPlaceHolder2" runat="server">
   
 <textarea id="editor" name="content" style="width:700px;height:300px;"></textarea>
 
</asp:Content>

注意：

整个配置过程中，需要注意upload_json.ashx、file_manager_json.ashx等文件的路径问题
