通过使用RDotnet和C#，如何在C#RichTextBox中显示我的R代码输出？

是否可以从rodotnet获取变量值并在RichTextBox中显示该值

 CharacterVector charVec = engine.CreateCharacterVector(new[] { txtgetUser.Text.ToString() });
        engine.SetSymbol("username", charVec);
        engine.Evaluate("user <- getUser(username)");
        engine.Evaluate("user$toDataFrame()");
        engine.Evaluate("friends <- user$getFriends()");

CharacterVector charVec=engine.CreateCharacterVector（新[]{txtgetUser.Text.ToString（）}）；
engine.SetSymbol（“用户名”，charVec）；
engine.Evaluate（“user一个简单的例子，我希望它能帮助：

            engine.Evaluate("x<-c(1:10)");
            string[] text = engine.Evaluate("x").AsCharacter().ToArray();

            StringBuilder builder = new StringBuilder();
            foreach (string value in text)
            {
                builder.Append(value);
            }
            richTextBox1.Text = builder.ToString();

engine.x
