推荐答案
代码正确，但是您应该执行以下两个步骤：
That code is Correct but you should do two steps more:
右键单击您的项目名称，然后选择在文件资源管理器上打开文件夹
Right click on your project name, then select Open Folder On File Explorer
粘贴该地址上名为 crystalreportviewers13 的文件夹（项目根目录）
Paste the folder with name crystalreportviewers13on this address (Project Root)
在p之后消除这种情况，返回到Visual Studio中的解决方案，如果该文件夹是隐藏的，则可以执行以下操作：
After paste that, come back to your solution in visual studio, if the folder is hidden, you can do this:
单击显示全部文件按钮
Click Show All File button
然后右键单击名称为 crystalreportviewers13 且没有颜色图标的文件夹，然后选择包含在项目中
then Right click on the folder with name crystalreportviewers13 which no color icon and choose Include In Project
