Mongo没有过期的旧收藏品.我检查以确保我的索引是类型日期.
var keys = IndexKeys.Ascending("expiry");
var options = IndexOptions.SetTimeToLive(TimeSpan.FromMinutes(1));
collection.EnsureIndex(keys, options);
this.ExpireDate = new BsonDateTime(DateTime.UtcNow.AddMinutes(5));
var insertResult = collection.Insert(this);
任何提示都将很高兴.
[
{
"v" : 1,
"key" : {
"_id" : 1
},
"ns" : "Showsv1.ShowInfo",
"name" : "_id_"
},
{
"v" : 1,
"key" : {
"expiry" : 1
},
"ns" : "Showsv1.ShowInfo",
"name" : "expiry_1",
"expireAfterSeconds" : 60
}
]
"expiry" : ISODate("2013-02-15T02:40:45.876Z")
最佳答案 在ExpireTime属性之上缺少[BsonElement(“expiry”)]的代码.
谢谢@WiredPrairie的提示.
