该代码是正确的，但您应该多做两步:
That code is Correct but you should do two steps more:
右击你的项目名称，然后选择Open Folder On File Explorer
将名称为crystalreportviewers13的文件夹粘贴到此地址(项目根目录)
Paste the folder with name crystalreportviewers13on this address (Project Root)
粘贴之后，回到你在visual studio中的解决方案，如果文件夹被隐藏，你可以这样做:
After paste that, come back to your solution in visual studio, if the folder is hidden, you can do this:
点击显示所有文件按钮
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 Include In Project
then Right click on the folder with name crystalreportviewers13 which no color icon and choose Include In Project
<script type="text/javascript" src="/crystalreportviewers13/js/crviewer/crv.js"></script>
