Asp.net - The type or namespace name 'App_Code' does not exist in the namespace 'xxx' (are you missing an assembly reference?)

  我在 项目 下面创建一个 App_Code的文件夹,然后在其下创建自定义的类,但是当我在该项目下别的地方使用时报错:

The type or namespace name 'App_Code' does not exist in the namespace 'xxx' (are you missing an assembly reference?)

  解决方案:

    1,在创建的类上右键,选择 Properties,如图:

Asp.net - The type or namespace name 'App_Code' does not exist in the namespace 'xxx' (are you missing an assembly reference?)

  2,将 Build Action 属性设置为 Compile,如图:

Asp.net - The type or namespace name 'App_Code' does not exist in the namespace 'xxx' (are you missing an assembly reference?)

即可.
