动态编译
AssemblyInfo.cs
AppDomain.CurrentDomain.AppendPrivatePath("");
AppDomain.CurrentDomain.SetupInformation.PrivateBinPath="";
/keyfile:vv.snk
AppDomainSetup.ConfiguraitonFile属性就是指的这个
<runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <probing privatePath="Castle;Core;Module;UI;Misc;"/> </assemblyBinding></runtime>static Program()
{
AppDomain.CurrentDomain.SetData("PRIVATE_BINPATH", "Castle;Core;Module;UI;Misc;");
AppDomain.CurrentDomain.SetData("BINPATH_PROBE_ONLY", "Castle;Core;Module;UI;Misc;");
var m = typeof(AppDomainSetup).GetMethod("UpdateContextProperty", BindingFlags.NonPublic | BindingFlags.Static);
var funsion = typeof(AppDomain).GetMethod("GetFusionContext", BindingFlags.NonPublic | BindingFlags.Instance);
m.Invoke(null, new object[] { funsion.Invoke(AppDomain.CurrentDomain, null), "PRIVATE_BINPATH", "Castle;Core;Module;UI;Misc;" });
}
嗯，迫不及待的编译，运行！哇！
/// </summary>
[STAThread]
static void Main()
{
AppDomain.CurrentDomain.SetupInformation.ConfigurationFile = "Data\MyApp.Config";
Application.Run(new MyAppForm());
}
……在此调试，惊奇的发现这个属性设置居然完全没有效果，语句执行完后，该属性值依然是默认值。于是查文档啊，百度啊，谷歌啊~ 最后终于知道设置config的正确方法。
AppDomain.CurrentDomain.SetData("APP_CONFIG_FILE", path);
嗯，这个这个……不是微软在害人吗
AppDomainSetup setup = new AppDomainSetup(); setup.ConfigurationFile = Path.GetFullPath(appConfig); AppDomain domain = AppDomain.CreateDomain( Guid.NewGuid().ToString(), AppDomain.CurrentDomain.Evidence, setup); domain.UnhandledException += new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException); var ty= typeof(Program); Program prog = domain.CreateInstanceAndUnwrap(ty.Assembly.FullName, ty.FullName) as Program; prog.Method(args); 最好不要hack。 以上来自stackoverflow 最好不要hack

然后是MyForm.cs，就是用来动态编译的cs：
using System;
using System.Drawing;
using System.Windows.Forms;
class MyForm : Form
{
public MyForm()
{
this.Text = "Hello World";
this.StartPosition = FormStartPosition.CenterScreen;
}
public static void Main()
{
Application.Run(new MyForm());
}
}
在 cp.CompilerOptions 中 加一句 /target:winexe 就可以了 默认是 Console app

上面代码是动态编译生成一个DLL，生成没问题，现在DLL中的方法返回的是字符串！！如何在动态库中使用图片资源？例如上面的方法，我可以返回一个image 求大神帮忙
objCompilerParams.EmbeddedResources.Add(fileName);
//获取资源中的图片
protected Bitmap GetResImage(string resourceName)
{
Bitmap resImage = null;
try
{
Stream stream = this.GetType().Assembly.GetManifestResourceStream(resourceName);
if (stream != null)
{
Bitmap bmp = new Bitmap(stream);
resImage = CloneBitmap(bmp);
bmp = null;
stream.Close();
stream = null;
}
}
catch { }
return resImage;
}
终于OK了！！
Stream stream = Assembly.GetExecutingAssembly().GetManifestResourceStream(projectName + "".bbb.jpg"");
后面的文件名这样写不对！！！
var ass = Assembly.GetExecutingAssembly();
foreach (var file in ass.GetManifestResourceNames())
{
}
直接用这个file就可以了！~！！感谢各位这两天的帮忙！！！散分了
