c# - CSharpCodeProvider CompilerParameters 使用 System.Data 错误

Question

我正在使用VS2010，只要我添加该行“DataTable table = null;”，这里发生的错误是代码：

       public static object GetLambdaResult(string expression)
       {
        string className = "ExecuteLambda";
        string methodName = "Run";
        var providerDic = new Dictionary<string, string>() { { "CompilerVersion",   "v4.0" } };
        ICodeCompiler complier = (new CSharpCodeProvider(providerDic).CreateCompiler());
        CompilerParameters paras = new CompilerParameters();

        paras.GenerateExecutable = false;
        paras.GenerateInMemory = true;
        paras.ReferencedAssemblies.Add("System.dll");
        paras.ReferencedAssemblies.Add("System.Data.dll");

        StringBuilder classSource = new StringBuilder();
        classSource.Append("using System; \n");
        classSource.Append("using System.Data; \n");
        classSource.Append("namespace AutoRun \n");
        classSource.Append("{\n");
        classSource.AppendFormat("  public class {0} \n", className);
        classSource.Append("  {\n");
        classSource.AppendFormat("       public static  object {0}()\n", methodName);
        classSource.Append("       {\n");
        classSource.Append("             DataTable table= null;\n");
        classSource.AppendFormat("             return {0};\n", expression);
        classSource.Append("       }\n");
        classSource.Append("  }\n");
        classSource.Append("}");
        CompilerResults result = complier.CompileAssemblyFromSource(paras, classSource.ToString());
        Assembly assembly = result.CompiledAssembly;
        object eval = assembly.CreateInstance("AutoRun." + className);
        MethodInfo method = eval.GetType().GetMethod(methodName);
        object reobj = method.Invoke(eval, null);
        GC.Collect();
        return reobj;
    }

我得到一个 FileNotFoundException，{“无法加载文件或程序集”文件：/// C:\\Users\\Administrator\\AppData\\Local\\Temp\\12azlzyr.dll“或其依赖项之一

. 系统找不到指定的文件。“：”文件：///C:\\Users\\Administrator\\AppData\\Local\\Temp\\12azlzyr.dll”

问题是 classSource.Append("DataTable table= null;\n"); 和
paras.ReferencedAssemblies.Add("System.Data.dll"); 我还不知道怎么解决

经过长时间的搜索，我找到了解决方案，需要添加xml引用paras.ReferencedAssemblies.Add("System.XML.dll");
