動的にコンパイルされたフォームからデータを取得

Question

私は動的にコンパイルされたフォームに静的変数_testVarを持っています。私はそれを私のメインプログラムから得ることができますか？私は関数を実行することができますが、私は値を返すことはできません。私はrefで試しましたが、うまくいきません。

例Iは、Form1クラスの内部テスト機能を実行

using System; 
using System.CodeDom.Compiler; 
using System.IO; 
using Microsoft.CSharp; 

namespace myConsoleCompiler 
{ 
    class Program 
    { 
     static void Main(string[] args) 
     { 
      using (var foo = new CSharpCodeProvider()) 
      { 
       var parameters = new CompilerParameters 
       { 
        GenerateInMemory = true, 
        GenerateExecutable = false 
       }; 

       parameters.ReferencedAssemblies.Add("System.dll"); 
       parameters.ReferencedAssemblies.Add("System.Core.dll"); 
       parameters.ReferencedAssemblies.Add("System.Drawing.dll"); 
       parameters.ReferencedAssemblies.Add("System.Windows.Forms.dll"); 

       var source = File.ReadAllText("form.txt"); 
       CompilerResults results = foo.CompileAssemblyFromSource(parameters, source); 
       Type type = results.CompiledAssembly.GetType("myForm.Form1"); 
       object compiledObject = Activator.CreateInstance(type); 

       // Execure test function from dynamically compiled form 
       type.GetMethod("test").Invoke(compiledObject, new object[] { }); 
      } 
     } 
    } 
}

      this.Controls.Add(this.richTextBox1); 
      this.Name = "Form1"; 
      this.Text = "Form1"; 
      this.ResumeLayout(false);

FieldInfo info = type.GetField("_testVar", BindingFlags.Public | BindingFlags.Static); 
object value = info.GetValue(null);
