Generating DLL assembly dynamically at run time
提问by 7wp
Currently I have some code that is being generated dynamically. In other words, a C# .cs file is created dynamically by the program, and the intention is to include this C# file in another project.
目前我有一些动态生成的代码。换句话说，程序动态创建了一个 C# .cs 文件，目的是将这个 C# 文件包含在另一个项目中。
The challenge is that I would like to generate a .DLL file instead of generating a C# .cs file so that it could be referenced by any kind of .NET application (not only C#) and therefore be more useful.
挑战在于我想生成一个 .DLL 文件而不是生成一个 C# .cs 文件，以便它可以被任何类型的 .NET 应用程序（不仅仅是 C#）引用，因此更有用。

using System.CodeDom.Compiler;
using System.Diagnostics;
using Microsoft.CSharp;
CSharpCodeProvider codeProvider = new CSharpCodeProvider();
ICodeCompiler icc = codeProvider.CreateCompiler();
System.CodeDom.Compiler.CompilerParameters parameters = new CompilerParameters();
parameters.GenerateExecutable = false;
parameters.OutputAssembly = "AutoGen.dll";
CompilerResults results = icc.CompileAssemblyFromSource(parameters, yourCodeAsString);

Right now, your best bet is CSharpCodeProvider; the plans for 4.0 include "compiler as a service", which will make this fully managed.
现在，你最好的选择是CSharpCodeProvider；4.0 的计划包括“编译器即服务”，这将使其得到全面管理。

The non-deprecated way of doing it (using .NET 4.0 as previous posters mentioned):
不推荐使用的方法（使用 .NET 4.0 作为前面提到的海报）：
using System.CodeDom.Compiler;
using System.Reflection;
using System;
public class J
{
public static void Main()
{
System.CodeDom.Compiler.CompilerParameters parameters = new CompilerParameters();
parameters.GenerateExecutable = false;
parameters.OutputAssembly = "AutoGen.dll";
CompilerResults r = CodeDomProvider.CreateProvider("CSharp").CompileAssemblyFromSource(parameters, "public class B {public static int k=7;}");
//verify generation
Console.WriteLine(Assembly.LoadFrom("AutoGen.dll").GetType("B").GetField("k").GetValue(null));
}
}
