为什么即使在成功导入 240 个文档后我得到的总数仍为零？
Why i am getting the total count as ZERO even after importing 240 documents succesfully?
实际上我正在学习 MongoDB 并且我在导入 JSON 文件（位于我的笔记本电脑的桌面上）时遇到了困难
我的 JSON 文件是一个包含 240 个元素的数组，每个元素都具有类似的类型，如下所示（我在数组中添加了两个这样的文档，类似地，其他 238 个具有相同形式的文档出现在同一个数组中） :-

我也试过使用这个命令：-

有人可以帮助我，为什么我得到的计数值为 ZERO？？
尝试使用 Studio 3T(https://studio3t.com/download/)。 GUI 支持 import/export JSON/CSV 等..
缺少文件名。
使用：
mongoimport --jsonArray --db movie --collection movies --file C:\Users\adity\Desktop\yourfilename.json
而不是：
mongoimport --jsonArray --db movie --collection movies --file C:\Users\adity\Desktop\.
或在您的 CMD 中 cd Desktop 并提供：
