c＃Mongo db FindAll（）

Question

我是MongoDB和C＃的新手。我不知道如何从我的收藏中获取所有数据＆＃34; kljenti＆＃34;。

任何人都可以帮助我吗？

以下是我的代码

package com.poc.sort;

/**

import java.util.ArrayList;
import java.util.List;

import org.apache.commons.collections4.CollectionUtils;

public class TestChapterSort {

    public static void main(String[] args) {
        List<String> chapters = new ArrayList<String>();

        chapters.add("1.1");
        chapters.add("1.2");
        chapters.add("1");
        chapters.add("1.3");
        chapters.add("1.1.1");
        chapters.add("5.6");
        chapters.add("1.1.10");
        chapters.add("4");
        chapters.add("1.1.9");
        chapters.add("1.2.1.10");
        chapters.add("2.1.1.4.5");

        chapters.add("1.2.1.11");

        TestChapterSort wer = new TestChapterSort();

    }

    }

    private boolean checkIfProper(int subLvl, String[] compChapterAr, String[] currChapterAr) {
        int subLvlCk = subLvl - 1;
        int compChapterSub;
        int currChapterSub;

            currChapterSub = parseToInt(currChapterAr, subLvlCk);
            if (compChapterSub < currChapterSub) {

            subLvlCk--;
        }
        return true;
    }

}

应该是这样的：

  

var allDocuments = collection.Find（new   。BsonDocument（））ToListAsync（）结果。
