如何检查与mongodb的连接

Question

我使用MongoDB驱动程序连接到数据库.当我的表单加载时,我想设置连接并检查它是否正常.我是这样做的:

var connectionString = "mongodb://localhost";
var client = new MongoClient(connectionString);
var server = client.GetServer();
var database = server.GetDatabase("reestr");

但我不知道如何检查连接.我试图重复这段代码try-catch,但无济于事.即使我创建了一个不正确的connectionString,我仍然无法获得任何错误消息.

Answer 1

要使用新的3.0驱动程序ping服务器:

var database = client.GetDatabase("YourDbHere");

database.RunCommandAsync((Command<BsonDocument>)"{ping:1}")
        .Wait();

Answer 2

有一个ping方法:

var connectionString = "mongodb://localhost";
var client = new MongoClient(connectionString);
var server = client.GetServer();
server.Ping();

Answer 3

2.4.3的完整示例 - 其中"client.GetServer()"不可用.基于"保罗凯斯特"的回答.

client = new MongoClient("mongodb://localhost");
database = client.GetDatabase(mongoDbStr);
bool isMongoLive = database.RunCommandAsync((Command<BsonDocument>)"{ping:1}").Wait(1000);

if(isMongoLive)
{
    // connected
}
else
{
    // couldn't connect
}
