mongosh 方法

The toArray() method returns an array that contains all the documents from a cursor. The method iterates completely the cursor, loading all the documents into RAM and exhausting the cursor.

返回：	一个文档数组。

Consider the following example that applies toArray() to the cursor returned from the find() method:

var allProductsArray = db.products.find().toArray();
if (allProductsArray.length > 0) { printjson (allProductsArray[0]); }

The variable allProductsArray holds the array of documents returned by toArray().
