如何从Excel中导入documentDB中的批量数据？

我已经浏览了一天，关于如何从excel文件插入到documentDB中的批量数据，但我没有得到任何信息。

我可以从excel文件读取数据，并逐个插入到documentDB中

Service service = new Service(); foreach(data in exceldata) //exceldata contains set of rows { var student = new Student(); student.id= ""; student.name = data.name; student.age = data.age; student.class = data.class; student.id = service.savetoDocumentDB(collectionLink,student); //collectionlink is a string stored in web.config students.add(student); } Class Service { public async Task<string> AddDocument(string collectionLink, Student data) { this.DeserializePayload(data); var result = await Client.CreateDocumentAsync(collectionLink, data); return result.Resource.Id; } } 

我可以在一个实例中插入所有logging吗？

任何帮助将是非常可观的。

更新（4/8/15）： DocumentDB刚发布了一个数据导入工具，它支持JSON文件，MongoDB，SQL Server和CSV文件。 你可以在这里find它： http : //www.microsoft.com/en-us/download/details.aspx?id=46436

原始答案：

DocumentDB不支持从Excel文件批量导入…但是，您可以利用DocumentDB的存储过程使批量导入更友好一些！

从MSDN检查Ryan的样本 ：

 /** * This script called as stored procedure to import lots of documents in one batch. * The script sets response body to the number of docs imported and is called multiple times * by the client until total number of docs desired by the client is imported. * @param {Object[]} docs - Array of documents to import. */ function bulkImport(docs) { var collection = getContext().getCollection(); var collectionLink = collection.getSelfLink(); // The count of imported docs, also used as current doc index. var count = 0; // Validate input. if (!docs) throw new Error("The array is undefined or null."); var docsLength = docs.length; if (docsLength == 0) { getContext().getResponse().setBody(0); } // Call the CRUD API to create a document. tryCreate(docs[count], callback); // Note that there are 2 exit conditions: // 1) The createDocument request was not accepted. // In this case the callback will not be called, we just call setBody and we are done. // 2) The callback was called docs.length times. // In this case all documents were created and we don't need to call tryCreate anymore. Just call setBody and we are done. function tryCreate(doc, callback) { var isAccepted = collection.createDocument(collectionLink, doc, callback); // If the request was accepted, callback will be called. // Otherwise report current count back to the client, // which will call the script again with remaining set of docs. // This condition will happen when this stored procedure has been running too long // and is about to get cancelled by the server. This will allow the calling client // to resume this batch from the point we got to before isAccepted was set to false if (!isAccepted) getContext().getResponse().setBody(count); } // This is called when collection.createDocument is done and the document has been persisted. function callback(err, doc, options) { if (err) throw err; // One more document has been inserted, increment the count. count++; if (count >= docsLength) { // If we have created all documents, we are done. Just set the response. getContext().getResponse().setBody(count); } else { // Create next document. tryCreate(docs[count], callback); } } }
