如何在ASP.Net Web表单中使用Roslyn执行C＃代码？ [英] How I can execute C# code using Roslyn in ASP.Net web form?
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 ％>
< span class =code-keyword>< asp：Content runat = server ID = FeaturedContent ContentPlaceHolderID = < span class =code-keyword> FeaturedContent >
< section class = 精选 >
< div class = < span class =code-keyword> content-wrapper >
< hgroup class = title >
< span class =code-keyword>< 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 >
< <跨度class =code-leadattribute> 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 < span class =code-keyword>>
< / 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（< span class =code-keyword> 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??
< blockquote>
如果你是asp.net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。

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.net 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.
