这是代码。我现在还在代码隐藏中遇到错误，即变量已经存在并且方法具有相同的签名，但我无法在代码隐藏的任何位置找到这些重复项。

最佳答案
我不会保留这两种解决方案，而是将网站项目转换为 WAP。
您需要将网站项目中 app_code 文件夹中的所有内容移动到单独的类库中，或者直接将它们包含在 WAP 中(可能没有 app_code 文件夹，因为这具有特殊意义)，在这种情况下，它们'将被编译到主 WAP 程序集中。
您可能需要使用命名空间等才能使其正常工作，但影响应该很小。主要区别(和好处)是代码是在编译时构建的，并且您的源代码(*.cs)不会部署到服务器。
另请注意，在 VS 中，有一个上下文菜单选项可将网站项目实体转换为 Web 应用程序实体。这将创建 WAP 所需的 .designer.cs 文件，并在解决方案资源管理器中组织文件 - .aspx、.cs 和 .designer.cs 文件将显示为可扩展节点。
Here's an excellent article on MSDN covering the conversion process .
运行 WAP 后，添加服务就像右键单击 - 添加新项目一样简单...
关于wcf - 在我的 Web 应用程序项目中重用网站项目中的代码，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/8670294/
