EF 数据版本号，处理具体使用方法 RowVersion / Timestamp 使用方法。进行自动处理并发修改

/*
* <div class="form-group">          // 原始
* <div class="form-group hidden">   // 修改后
*
*
*  原始：  @Html.EditorFor(model => model.RowVersion, new { htmlAttributes = new { @class = "form-control" } })
*  修改后：@Html.HiddenFor(model => model.RowVersion, new { htmlAttributes = new { @class = "form-control" } })
