如何在ASP.Net Web表单中使用Roslyn执行C＃代码？

本文介绍了如何在ASP.Net Web表单中使用Roslyn执行C＃代码？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我在ASP.Net中使用roslyn编译器执行C＃的执行代码。但是，我使用ASP.Net Web表单来构建用于执行代码的用户界面。所以，我想从一个文本框中获取代码，然后通过编译按钮将结果显示在另一个文本框中。 所以，我有这个控件：

<％@ Page 标题 = 主页 语言 = C＃ MasterPageFile = 〜/ Site.Master AutoEventWireup = true CodeBehind = Default.aspx.cs 继承 = WebApplication2._Default ％> < asp：Content runat = server ID = FeaturedContent ContentPlaceHolderID = FeaturedContent > < section class = 精选 > < div class = content-wrapper > < hgroup class = title > < h1 > 编译工具< / h1 > < / hgroup > < p > 您可以使用Microsoft的Roslyn编译器编译C＃的源代码< / p > < br / > < p > < asp：TextBox ID = TextBox3 runat = server 高度 = 185px 宽度 = 480px OnTextChanged = TextBox3_TextChanged > < / asp：TextBox > < / p > < p > < asp：Button ID = Button2 runat = server onclick = Button_Click 文本 = 编译 ForeColor = 黑色 / > < / p > < p > < asp：TextBox ID = TextBox2 runat = server 高度 = 138px 宽度 = 390px > < / asp：TextBox > < / p > < / div > < / section > < / asp：内容 > < asp：内容 runat = 服务器 ID = BodyContent ContentPlaceHolderID = 主要内容 > < / asp：Content >

这里使用C＃的Handler事件：

使用系统; 使用 System.Collections.Generic; 使用 System.Linq; 使用 System.Text; 使用 System.Web; 使用 System.Web.UI; 使用 System.Web.UI.WebControls; 使用 System.ComponentModel; 使用 Roslyn.Scripting; 使用 Roslyn.Scripting.CSharp; 命名空间 WebApplication2 { public partial class _Default：Page { 受保护 void Page_Load（ object sender，EventArgs e） { } protected void Button_Click（ object sender，EventArgs e） { var engine = new ScriptEngine（）; var session = engine.CreateSession（）; String code = TextBox3.Text; session.Execute（code）; } 受保护 void TextBox3_TextChanged（ object sender，EventArgs e） { } } }

如何在TextBox2中显示Code（TextBox3）的执行结果？ br $> b $ b 我在ASP.Net环境中初学者，任何帮助??

解决方案

如果你是asp的初学者，我想知道你想要实现的是什么。 如果您正在尝试构建一个工具，您可以粘贴代码片段并查看它们是否有效 - 类似于快速测试 - 市场上已有工具用于这个。例如 linqpad / [ ^ ] dotnetfiddle / [ ^ ] csharppad [ ^ ] Snippet Compiler / [ ^ ] 还有许多其他人列出在哪里 [ ^ ] 但是，如果你是仍然有兴趣继续y你正在计划，然后请准备好被压垮一点并通过这篇文章 [ ^ ]，相当全面。 [请接受/投票给你的答案或解决方案以鼓励参与]

I have peice of code in ASP.Net for execute code of C# using roslyn compiler. However, I use ASP.Net web forms to build user interface for execute the code. So,I want to take code from one textbox and by "Compile" button I show the result in another textbox. So, I have this controls:

<%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="WebApplication2._Default" %> <asp:Content runat="server" ID="FeaturedContent" ContentPlaceHolderID="FeaturedContent"> <section class="featured"> <div class="content-wrapper"> <hgroup class="title"> <h1>Compiler Tool</h1> </hgroup> <p> You can compile your source code of C# using Roslyn Compiler from Microsoft</p> <br/> <p> <asp:TextBox ID="TextBox3" runat="server" Height="185px" Width="480px" OnTextChanged="TextBox3_TextChanged"></asp:TextBox> </p> <p> <asp:Button ID="Button2" runat="server" onclick="Button_Click" Text="Compile" ForeColor="Black" /> </p> <p> <asp:TextBox ID="TextBox2" runat="server" Height="138px" Width="390px" ></asp:TextBox> </p> </div> </section> </asp:Content> <asp:Content runat="server" ID="BodyContent" ContentPlaceHolderID="MainContent"> </asp:Content>

And here the Handler event for it using C#:

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.ComponentModel; using Roslyn.Scripting; using Roslyn.Scripting.CSharp; namespace WebApplication2 { public partial class _Default : Page { protected void Page_Load(object sender, EventArgs e) { } protected void Button_Click(object sender, EventArgs e) { var engine = new ScriptEngine(); var session = engine.CreateSession(); String code = TextBox3.Text; session.Execute(code); } protected void TextBox3_TextChanged(object sender, EventArgs e) { } } }

How could I show the result of execution of Code (TextBox3) in TextBox2?? Iam beginner in ASP.Net environment, Any help??

Hi, If you are a beginner in asp I wonder what you are trying to achieve by this. If you are trying to build a tool where you would paste code snippets and see if they work - something like a quick test - there are tools in the market already for this. Such as linqpad/[^] dotnetfiddle/[^] csharppad[^] Snippet Compiler/[^] And a host of others listed here[^] However, if you are still interested in going ahead with what you are planning, then please be prepared to be overwhelmed a bit and go through this article[^], pretty comprehensive.
