十七、.NET CORE上传附件方法（From表单上传）
@model BaseFramePro.Models.Entities.EnvironType @{ Layout = null; } <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>上传升级文件</title> <meta name="renderer" content="webkit"> <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"> <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1"> <link rel="stylesheet" href="~/layuimini/lib/layui-v2.5.5/css/layui.css" media="all"> <link rel="stylesheet" href="~/layuimini/css/public.css" media="all"> </head> <body> <div class="layuimini-container"> <div class="layuimini-main"> <fieldset class="layui-elem-field layui-field-title" style="margin-top: 50px;"> <legend>上传升级文件</legend> </fieldset> @Html.AntiForgeryToken() @*<form class="layui-form" method="post" enctype="multipart/form-data" asp-controller="EnvironUpgrade" asp-action="FileSave" asp-route-id="@Model.TypeID">*@ <form class="layui-form" method="post" enctype="multipart/form-data" action="/api/EnvironUpgrade/FileSave?id=@Model.TypeID" > <div> <div> <div class="layui-form-item"> <label class="layui-form-label">选择升级文件：</label> <div class="layui-input-block"> <input type="file" class="layui-upload-choose" name="files" /> <button class="layui-btn" lay-submit="" type="submit">上传</button> </div> </div> </div> </div> </form> </div> </div> <style type="text/css"> .layui-form-label { width: 100px; } .layui-input-block { margin-left: 130px; } </style> <script src="~/layuimini/lib/layui-v2.5.5/layui.js" charset="utf-8"></script> <script> layui.use(['form', 'layer', 'laydate'], function () { var form = layui.form , $ = layui.jquery , layer = layui.layer; }); </script> </body> </html>
@Model.TypeID为我的赋值参数，可以换成自己的，或者直接写值
@*<form class="layui-form" method="post" enctype="multipart/form-data" asp-controller="EnvironUpgrade" asp-action="FileSave" asp-route-id="@Model.TypeID">*@这种也是form的方法
/// <summary>
/// 上传升级包(方法1)
