在https://www.typescriptlang.org/docs/home.html的文档中，示例使用如下形式：
require在Visual Studio中的Typescript项目的模板中，示例如下：
import两者有何不同？ public static String getYyyy(String date) {
String time = date;
try {
SimpleDateFormat format = new SimpleDateFormat("dd MMM yyyy");
Date date1 = format.parse(date);
if (date1 != null) {
time = new SimpleDateFormat("yyyy").format(date1);
}
} catch (ParseException e) {
e.printStackTrace();
}
return time;
}
函数有什么作用？是否有 string username = "user";
string password = "password";
string mongoDbAuthMechanism = "SCRAM-SHA-1";
MongoInternalIdentity internalIdentity =
new MongoInternalIdentity("admin", username);
PasswordEvidence passwordEvidence = new PasswordEvidence(password);
MongoCredential mongoCredential =
new MongoCredential(mongoDbAuthMechanism,
internalIdentity, passwordEvidence);
List<MongoCredential> credentials =
new List<MongoCredential>() {mongoCredential};
MongoClientSettings settings = new MongoClientSettings();
// comment this line below if your mongo doesn't run on secured mode
settings.Credentials = credentials;
String mongoHost = "127.0.0.1";
MongoServerAddress address = new MongoServerAddress(mongoHost);
settings.Server = address;
MongoClient client = new MongoClient(settings);
命令的确定规范？
