CodeDomProvider 编译 .net3.5

最近研究CodeDomProvider，但是编译linq时总是报错，编译决是不过，后来在国外的网站找到了原来CodeDomProvider是有版本的，代码如下：

// 创建编译器对象

            CodeDomProvider p = new CSharpCodeProvider(new Dictionary<string, string>() { { "CompilerVersion", "v3.5" } });//CodeDomProvider.CreateProvider("CSharp");

            //ICodeCompiler cc = p.CreateCompiler();
            // 设置编译参数
            CompilerParameters options = new CompilerParameters();
            options.IncludeDebugInformation = true;
            options.ReferencedAssemblies.Add("System.dll");
            options.ReferencedAssemblies.Add(@"C:\Program Files\Reference Assemblies\Microsoft\Framework\v3.5\System.Core.dll");
            options.ReferencedAssemblies.Add("System.Data.dll");
            options.ReferencedAssemblies.Add(@"C:\Program Files\Reference Assemblies\Microsoft\Framework\v3.5\System.Data.DataSetExtensions.dll");
            options.ReferencedAssemblies.Add("System.Deployment.dll");
            options.ReferencedAssemblies.Add("System.Xml.dll");
            options.ReferencedAssemblies.Add(@"C:\Program Files\Reference Assemblies\Microsoft\Framework\v3.5\System.Xml.Linq.dll");
            options.ReferencedAssemblies.Add("System.Drawing.dll");
            options.ReferencedAssemblies.Add("System.Windows.Forms.dll");

            options.GenerateInMemory = true;
            options.OutputAssembly = "MyTest";
            // 开始编译
            //CodeSnippetCompileUnit cu = new CodeSnippetCompileUnit(code);
            CompilerResults cr = p.CompileAssemblyFromFile(options, code);
