MongoDB 导出、导入表

var srcTbl = "20161226";
var destTbl = "20161226-bak";

方式一：

MongoClient client;
MongoServer server;
MongoDatabase db;

MongoClientSettings setting = new MongoClientSettings();
setting.MaxConnectionPoolSize = 1000;
setting.MinConnectionPoolSize = 500;

client = new MongoClient(mongodb);

server = client.GetServer();
db = server.GetDatabase(database);

db.CreateCollection(destTbl);
db.GetCollection(srcTbl).FindAll().Foreach(doc =>
{
db.GetCollection(destTbl).Insert(doc); // start to replace
});

方式二：

Mongo目录下需文件：

libeay32.dll

mongoexport.exe

mongoimport.exe

ssleay32.dll
