前言:
目前朋友们对“nethtml编辑”大约比较着重,朋友们都需要知道一些“nethtml编辑”的相关资讯。那么小编在网摘上网罗了一些有关“nethtml编辑””的相关资讯,希望姐妹们能喜欢,我们快快来学习一下吧!winform是一老技术,感觉都有点掉牙了(我近20年前就是从winform开始接触.net的);blazor,是微软技术圈里的新宠,正在被悉心照顾。当这一老一少的技术碰撞后,会有什么火花?
.net v6.0.0-preview.3,给winform和blazor结合带来了前提。 是我写的一个简单的demo,在winform窗体中引入blazor。
先看一下长什么样子:
是一个简单的用助记码查询药品的例子,输入框查询按钮,table的样式都是Bootstrap5.0的,外层是一个winform的Form窗体。
具体实现,先看项目文件csproj的不一样:Sdk要换成Microsoft.NET.Sdk.Razor,然后是要通过nuget引入这些包。
<Project Sdk="Microsoft.NET.Sdk.Razor"> <PropertyGroup> <OutputType>WinExe</OutputType> <TargetFramework>net6.0-windows</TargetFramework> <UseWindowsForms>true</UseWindowsForms> </PropertyGroup> <ItemGroup> <PackageReference Include="Dapper" Version="2.0.78" /> <PackageReference Include="Microsoft.AspNetCore.Components.WebView.WindowsForms" Version="6.0.0-preview.3.21201.13" /> <PackageReference Include="Microsoft.Extensions.DependencyInjection" Version="6.0.0-preview.3.21201.4" /> <PackageReference Include="Microsoft.NET.Sdk.Razor" Version="5.0.0-preview.8.20414.8" /> <PackageReference Include="System.Data.SqlClient" Version="4.8.2" /> </ItemGroup> <ItemGroup> <Content Update="wwwroot\app.css"> <CopyToOutputDirectory>Always</CopyToOutputDirectory> </Content> <Content Update="wwwroot\Query.razor"> <CopyToOutputDirectory>Always</CopyToOutputDirectory> </Content> <Content Update="wwwroot\css\bootstrap.min.css"> <CopyToOutputDirectory>Always</CopyToOutputDirectory> </Content> <Content Update="wwwroot\index.html"> <CopyToOutputDirectory>Always</CopyToOutputDirectory> </Content> <Content Update="wwwroot\js\bootstrap.min.js"> <CopyToOutputDirectory>Always</CopyToOutputDirectory> </Content> </ItemGroup> <ItemGroup> <None Update="wwwroot\app.css"> <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory> </None> <None Update="wwwroot\Query.razor"> <CopyToOutputDirectory>Always</CopyToOutputDirectory> </None> <None Update="wwwroot\index.html"> <CopyToOutputDirectory>Always</CopyToOutputDirectory> </None> </ItemGroup></Project>
通过csproj也知道,我是添加了wwwroot文件夹,并添加了一些前端文件:
index.html是一个模板页,引入一些css和js
<!DOCTYPE html><html><head> <meta charset="utf-8" /> <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no" /> <title>Blazor app</title> <base href="/" /> <link href="{PROJECT NAME}.styles.css" rel="stylesheet" /> <link href="app.css" rel="stylesheet" /> <link href="css/bootstrap.min.css" rel="stylesheet" /></head><body> <div id="app" class="container"></div> <div id="blazor-error-ui"> An unhandled error has occurred. <a href="" class="reload">Reload</a> <a class="dismiss"></a> </div> <script src="_framework/blazor.webview.js"></script> <script src="js/bootstrap.min.js"></script></body></html>
css和js就不说了,是前端的文件,重点看query.razor,这里实现了主要业务逻辑,业务数据+UI表现
@using Microsoft.AspNetCore.Components.Web@using Dapper@using System.Data.SqlClient;<div class="row"> <div class="col-1"></div> <div class="col-10"> <div class="input-group mb-3"> <input type="text" class="form-control" id="zjm" placeholder="请输入助记码" @bind="ZJM" aria-describedby="button-addon2"> <button class="btn btn-outline-secondary" type="button" @onclick="GetGoods" id="button-addon2">查询</button> </div> </div> <div class="col-1"></div></div>@code { private string ZJM { get; set; } List<Goods> list = new List<Goods>(); void GetGoods() { using (var con = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["sqlcon"].ConnectionString)) { if (string.IsNullOrWhiteSpace(ZJM)) { list = con.Query<Goods>("select top 30 spid,spmch,shpchd,shpgg from spkfk ").ToList(); } else { list = con.Query<Goods>("select top 30 spid,spmch,shpchd,shpgg from spkfk where zjm like @zjm ",new {zjm="%"+ZJM+"%" }).ToList(); } } }}<div class="row"> <table class="table table-striped table-hover"> <thead> <tr class="table-dark"> <th scope="col">编号</th> <th scope="col">名称</th> <th scope="col">产地</th> <th scope="col">规格</th> </tr> </thead> <tbody> @foreach (var item in list) { <tr> <td>@item.spid</td> <td>@item.spmch</td> <td>@item.shpchd</td> <td>@item.shpgg</td> </tr> } </tbody> </table></div>
怎么引入到form窗体中呢?这里有点像之前的winform中引入一个webview,这里换成了BlazorWebView。
using BlazorWinForm.wwwroot;using Microsoft.AspNetCore.Components.WebView.WindowsForms;using Microsoft.Extensions.DependencyInjection;using System.Windows.Forms;namespace BlazorWinForm{ public partial class frmMain : Form { public frmMain() { InitializeComponent(); var serviceCollection = new ServiceCollection(); serviceCollection.AddBlazorWebView(); var blazor = new BlazorWebView() { Dock = DockStyle.Fill, HostPage = "wwwroot/index.html", Services = serviceCollection.BuildServiceProvider(), }; blazor.AutoScroll = false; blazor.RootComponents.Add<Query>("#app"); Controls.Add(blazor); } } class Goods { public string spid { get; set; } public string spmch { get; set; } public string shpchd { get; set; } public string shpgg { get; set; } }}
总体下来,这种把winform+c#+html,css,js混合起来编程,即把丰富的前端框架引入进来,让winform表现更加灵活,强大,也不丢失cs架构对当前电脑的控制力(有很多行业是通过exe来对接专有设备的驱动的)。winform的UI之前是通过三方UI控件比如DevExpress来增强的,虽然有WPF,但还是在微软自己画的一个圈圈里转,blazor则是带来了丰富的前端库。另外,与之前winform嵌入webview不一样的是,blazor中的c#,可以方便的和winform来互动,语言相通,直接交流,比如你可以很轻松的在blazor的页里里new一个form出来。
Blazor进winform,是鸡肋还是革新?应该是仁者见仁,智者见智了。
