Question

I m 试图使用C#作为描述性语言,使用CSharpCodeProvider(使用VS2010和NET4.0)。我希望这些文字在经过最少许可的有限审校进行。目前,我只想在AppDomain(电话:CreateInstanceAnd Unwrap())上调一个班子,但我却成为例外。这里有些简化的法典转载了例外情况:

using System.Collections.Generic;
using Microsoft.CSharp;
using System.CodeDom;
using System.CodeDom.Compiler;

using System.Security.Policy;
using System.Security.Permissions;

using System.Runtime.Remoting;

namespace ConsoleApp
{
    class Program
    {
        static void Main(string[] args)
        {
            // set permissions
            PermissionSet permissions = new PermissionSet(PermissionState.None);
            permissions.AddPermission(new SecurityPermission( SecurityPermissionFlag.Execution));

            AppDomainSetup adSetup = new AppDomainSetup();
            adSetup.ApplicationBase = AppDomain.CurrentDomain.BaseDirectory;

            //Create a list of fully trusted assemblies
            Assembly[] asms = AppDomain.CurrentDomain.GetAssemblies();
            List<StrongName> sns = new List<StrongName>();
            for (int x = 0; x < asms.Length; x++)
            {
                StrongName sn = asms[x].Evidence.GetHostEvidence<StrongName>();
                if (sn != null && sns.Contains(sn) == false)
                    sns.Add(sn);
            }
            //this includes: "mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"            

            AppDomain domain = AppDomain.CreateDomain("NewAppDomain", AppDomain.CurrentDomain.Evidence, adSetup, permissions);//, sns);//, sn4, sn, sn2, sn3);
            try
            {
                String asmName = Assembly.GetExecutingAssembly().FullName;
                String typeName = typeof(ConsoleApp.ScriptRunner).FullName;
                //Throws exception here
                ScriptRunner scriptRunner = domain.CreateInstanceAndUnwrap(asmName, typeName) as ScriptRunner;
            }
            catch (SecurityException se)
            {
                System.Diagnostics.Debug.WriteLine(se.Message);
            }
            catch (Exception ex)
            {
                System.Diagnostics.Debug.WriteLine(ex.Message);
            }
        }
    }

    public class ScriptRunner : MarshalByRefObject
    {      
        public ScriptRunner()
        {
            //A breakpoint placed here is never reached.
            CompilerParameters param;
            param = new CompilerParameters();
            param.CompilerOptions = "";
            param.GenerateExecutable = false;
            param.GenerateInMemory = true;
            param.IncludeDebugInformation = false;

            // C# compiler
            CSharpCodeProvider codeProvider = new CSharpCodeProvider();  

            CompilerResults results = codeProvider.CompileAssemblyFromFile(param, "Danger.cs");           
        }
    }
}

这一例外正在从雕塑中提取,它是一个System.Reflection.TargetInventionException,内有System. Security.Exception。例外:

System.Reflection.TargetInvocationException was unhandled
  Message=Exception has been thrown by the target of an invocation.

因此,在我看来,调子要求完全信任。我补充说,它是一个完全相信的大会,但它没有效果。如果我确定允许不受限制的话,上述法典就有效:

PermissionSet permissions = new PermissionSet(PermissionState.Unrestricted);

但我想限制上诉人。我在这里做了什么错误?

晚间休息。如下。我在视力演播室接受测试。在一旁,我个人并不喜欢建筑商中的“地质”,因为真正的错误往往很少隐藏。以下步骤从构造者转向新的方法。

Ensure your Console App has a StrongName / Signed.

将斜体变量作为最后参数列入“应用数据”。创建网站。联系组织要求你科索尔阿普完全相信。

AppDomain domain = AppDomain.CreateDomain("NewAppDomain", AppDomain.CurrentDomain.Evidence, adSetup, permissions, sns.ToArray());

Change the asmName to use the Full File Path to your assembly.

String asmName = Assembly.GetExecutingAssembly().ManifestModule.FullyQualifiedName;

删除“创建” 安瓦拉布呼吁以下两条法典:

var handle = Activator.CreateInstanceFrom(domain, asmName, typeName);
var scriptRunner = (ScriptRunner)handle.Unwrap();

将所有你的法典从核查者翻译成新的方法,如“标准”。
添加“起步”方法。
```
scriptRunner.Start();
```

Add the FileIOPermission to read your Danger.cs file.

permissions.AddPermission(new FileIOPermission(PermissionState.None) { AllFiles = FileIOPermissionAccess.Read });
