如何将asp.net web forms web应用程序与mongodb连接

using MongoDB.Driver;

protected void Page_Load(object sender, EventArgs e)
{
    string connectionString = "mongodb://localhost:27017";
    MongoClient client = new MongoClient(connectionString);
    IMongoDatabase database = client.GetDatabase("mydb");
    IMongoCollection<BsonDocument> collection = database.GetCollection<BsonDocument>("mycollection");
    
    // 查询数据
    var filter = Builders<BsonDocument>.Filter.Empty;
    var documents = collection.Find(filter).ToList();
    
    // 处理数据
    foreach (var document in documents)
    {
        // 处理每个文档
    }
    
    // 插入数据
    var newDocument = new BsonDocument { { "key", "value" } };
    collection.InsertOne(newDocument);
    
    // 更新数据
    var updateFilter = Builders<BsonDocument>.Filter.Eq("key", "value");
    var update = Builders<BsonDocument>.Update.Set("key", "new value");
    collection.UpdateOne(updateFilter, update);
    
    // 删除数据
    var deleteFilter = Builders<BsonDocument>.Filter.Eq("key", "value");
    collection.DeleteOne(deleteFilter);
}
