在列表框VB.net中删除多个相同的值

如何删除列表框中的所有数据。尚不清楚，还有其他一些值只是希望仅显示此数据。只是想一次将它们全部删除。

您可以尝试使用此代码

[
    {
        _id: "1a2b3c4d5e6f7g8h9i",
        name: "Jane Doe",
        total: 7384,
        // next line is what I'm looking for
        // rank: 0 <-- it's the first item in an array after $sort
    },
    {
        _id: "a1b2c3d4e5f6g7h8i9",
        name: "John Doe",
        total: 7370,
        // next line is what I'm looking for
        // rank: 1 <-- it's the second item in an array after $sort
    },
    ...
]
