我正在尝试向现有项目添加新类。当我在Windows窗体应用程序项目中的System :: Windows :: Forms :: Form类下时，我的类正在工作。我想将我的类添加到该项目中，因为我希望所有类都在不同的文件中。但是，当我想编译时，我收到错误“语法错误：标识符'字符串'”。当我删除String对象时，一切都可以编译。哪里有问题？

我认为GenerateLabels类有问题。因为当那个类的实例不是inicializet我得到了那个错误。使用GenerateControls一切正常。
答案 0 :(得分：0)
我的代码中没有using namespace System;。你是否在复制/粘贴到网页时修剪它，或者你需要添加它吗？
我看到你通过完整的命名空间引用System :: Drawing :: Point和System :: Drawing :: Size，你可能只需要System :: String的using指令。
