尝试以编程方式编译和执行 C# 代码
本文关键字：执行 代码 编译 方式 编程 | 更新日期: 2023-09-27 18:32:16
以下是我的代码：
using System;
using System.Collections.Generic;
using System.Text;
using System.CodeDom.Compiler;
using System.IO;
using Microsoft.CSharp;
using System.Reflection;
namespace DynaCode
{
class Program
{
static void Main(string[] args)
{
string content = File.ReadAllText(@"D:'hi.cs");
string[] code = new string[content.Length];
char[] seperators = { ''n',''r',''t' };
code = content.Split(seperators);
CompileAndRun(code);
Console.ReadKey();
}
static void CompileAndRun(string[] code)
{
CompilerParameters CompilerParams = new CompilerParameters();
string outputDirectory = Directory.GetCurrentDirectory();
CompilerParams.GenerateInMemory = true;
CompilerParams.TreatWarningsAsErrors = false;
CompilerParams.GenerateExecutable = false;
CompilerParams.CompilerOptions = "/optimize";
string[] references = { "System.dll"};
CompilerParams.ReferencedAssemblies.AddRange(references);
CSharpCodeProvider provider = new CSharpCodeProvider();
CompilerResults compile = provider.CompileAssemblyFromSource(CompilerParams, code);
if (compile.Errors.HasErrors)
{
string text = "Compile error: ";
foreach (CompilerError ce in compile.Errors)
{
text += "rn" + ce.ToString();
}
throw new Exception(text);
}
//ExpoloreAssembly(compile.CompiledAssembly);
Module module = compile.CompiledAssembly.GetModules()[0];
Type mt = null;
MethodInfo methInfo = null;
if (module != null)
{
mt = module.GetType("DynaCore.DynaCore");
}
if (mt != null)
{
methInfo = mt.GetMethod("Main");
}
if (methInfo != null)
{
Console.WriteLine(methInfo.Invoke(null, new object[] { "here in dyna code" }));
}
}
static void ExpoloreAssembly(Assembly assembly)
{
Console.WriteLine("Modules in the assembly:");
foreach (Module m in assembly.GetModules())
{
Console.WriteLine("{0}", m);
foreach (Type t in m.GetTypes())
{
Console.WriteLine("t{0}", t.Name);
foreach (MethodInfo mi in t.GetMethods())
{
Console.WriteLine("tt{0}", mi.Name);
}
}
}
}
}
}
hi.cs 文件的内容如下：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
namespace DynaCore
{
class DynaCore
{
static public void Main(string[] args)
{
Console.WriteLine("hello, this is good");
}
}
}
这是我尝试运行此程序时遇到的错误：

我认为
这就是问题所在：
string content = File.ReadAllText(@"D:'hi.cs");
string[] code = new string[content.Length];
char[] seperators = { ''n',''r',''t' };
code = content.Split(seperators);
这个想法（我相信）是CompileAssemblyFromSource不采用单独的行 - 数组中的每个字符串都是一个完整的 C# 源文件。所以你可能只需要：
string[] code = new[] { File.ReadAllText(@"D:'hi.cs") };
请注意，即使您的第一个块做了正确的事情，您仍然会无缘无故地创建一个字符串数组 - 将其编写为：
string content = File.ReadAllText(@"D:'hi.cs");
char[] seperators = { ''n',''r',''t' };
string[] code = content.Split(seperators);
你不需要把你的代码拆分成这样的数组。
该数组用于传递多个源文件。
你可以尝试制作这样的代码
string content = File.ReadAllText(@Path.GetDirectoryName(Application.ExecutablePath) + "''r.cs");
char[] seperators = { ''n', ''r', ''t' };
string[] code = content.Split(seperators);
CompilerParameters CompilerParams = new CompilerParameters();
string outputDirectory = Directory.GetCurrentDirectory();
CompilerParams.GenerateInMemory = true;
CompilerParams.TreatWarningsAsErrors = false;
CompilerParams.GenerateExecutable = false;
CompilerParams.CompilerOptions = "/optimize";
CompilerParams.GenerateExecutable = false;
CompilerParams.OutputAssembly = "r.dll";
FileStream fileStream = File.Open(Path.GetDirectoryName(Application.ExecutablePath) + "''Output''r.dll",FileMode.Open);
string references = fileStream.Name;
CompilerParams.ReferencedAssemblies.Add(references);
fileStream.Close();
CSharpCodeProvider provider = new CSharpCodeProvider();
CompilerResults compile = provider.CompileAssemblyFromFile(CompilerParams, Path.GetDirectoryName(Application.ExecutablePath) + "''r.cs");
if (compile.Errors.HasErrors)
{
string text = "Compile error: ";
foreach (CompilerError ce in compile.Errors)
{
text += "rn" + ce.ToString();
}
throw new Exception(text);
}
Module module = compile.CompiledAssembly.GetModules()[0];
Type mt = null;
MethodInfo methInfo = null;
MemberInfo[] memberInfo;
//var dll = Assembly.LoadFile(references);
if (module != null)
{
mt = module.GetType("materialclassifier.ClassifierFiles");
}
if (mt != null)
{
memberInfo = mt.GetMembers();
methInfo = mt.GetMethod("main");
}
if (methInfo != null)
{
Console.WriteLine(methInfo.Invoke(null, new object[] { "here in dyna code" }));
}
它在我的代码中没有任何错误的情况下工作
