I need to compile assembly in memory, that can compile another one. There is a form with one button. Here is a code of the form
using System;
using System.IO;
using System.CodeDom;
using System.CodeDom.Compiler;
using System.Threading;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using Microsoft.CSharp;
namespace testC
{
public partial class Form1 : Form
{static string str_tb;
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
openkubik();
}
private void openkubik()
{
Thread th = new Thread(new ThreadStart(sborkakub));
th.Start();
}
private void sborkakub()
{
System.Security.Policy.Evidence evi = AppDomain.CurrentDomain.Evidence;
AppDomain assemblyDomain;
AppDomainSetup assemblyDomainSetup = new AppDomainSetup();
assemblyDomainSetup.ApplicationBase = System.Environment.CurrentDirectory;
assemblyDomainSetup.DisallowBindingRedirects = false;
assemblyDomainSetup.DisallowCodeDownload = true;
assemblyDomainSetup.ConfigurationFile = AppDomain.CurrentDomain.SetupInformation.ConfigurationFile;
assemblyDomainSetup.LoaderOptimization = LoaderOptimization.MultiDomainHost;
assemblyDomain = AppDomain.CreateDomain("AssemblyDomain", evi, assemblyDomainSetup);
assemblyDomain.DoCallBack(assamblykub);
}
private static void assamblykub() {
createtext();
System.CodeDom.Compiler.CodeDomProvider objCodeCompiler = System.CodeDom.Compiler.CodeDomProvider.CreateProvider("CSharp");
System.CodeDom.Compiler.CompilerParameters objCompilerParameters = new System.CodeDom.Compiler.CompilerParameters();
foreach (System.Reflection.Assembly asm in AppDomain.CurrentDomain.GetAssemblies()) {
objCompilerParameters.ReferencedAssemblies.Add(asm.Location);
}
objCompilerParameters.CompilerOptions = "/target:winexe";
objCompilerParameters.GenerateExecutable = true;
objCompilerParameters.GenerateInMemory = true;
objCompilerParameters.IncludeDebugInformation = false;
System.CodeDom.Compiler.CompilerResults objCompileResults = objCodeCompiler.CompileAssemblyFromSource(objCompilerParameters, str_tb);
if (objCompileResults.Errors.HasErrors) {
MessageBox.Show(String.Format("Error: Line>{0}, {1} # {2}", objCompileResults.Errors[0].Line, objCompileResults.Errors[0].ErrorText, objCompileResults.Errors[0].ErrorNumber));
return;
}
System.Reflection.Assembly objAssembly = objCompileResults.CompiledAssembly;
object objTheClass = objAssembly.CreateInstance("MainClass");
if ((objTheClass == null)) {
MessageBox.Show("Can\'t load class...");
return;
}
try {
objTheClass.GetType().InvokeMember("Main", System.Reflection.BindingFlags.InvokeMethod, null, objTheClass, null);
}
catch (Exception ex) {
MessageBox.Show(("Error:" + ex.Message));
}
}
private static void createtext()
{
FileStream tempfile = new FileStream((Application.StartupPath + "/temp_open.txt"), FileMode.Open, FileAccess.Read);
StreamReader tempfilesr = new StreamReader(tempfile, System.Text.Encoding.GetEncoding(1251));
str_tb = tempfilesr.ReadToEnd();
tempfilesr.Close();
tempfile.Close();
tempfile = null;
tempfilesr = null;
}
}
}
And the code of "temp_open.txt" file

}
}
When I click Button1 in first form -> appears second form. but when I click Button 1 in the second form I have an FileNotFound Exception. What am I doing wrong?
