Arrays 使用字符串和整数对数组进行数字排序
我有一个数组，它旁边有一个名字和一个分数，我需要它从高到低排序。我已经按字母顺序把它分类了Arrays 使用字符串和整数对数组进行数字排序,arrays,vb.net,sorting,Arrays,Vb.net,Sorting,我有一个数组，它旁边有一个名字和一个分数，我需要它从高到低排序。我已经按字母顺序把它分类了 Dim reply3 As String Dim name As String Dim score As Integer = 0 Dim classnum As Integer Dim filePath As String Dim reply As Integer Dim reply2 As Integer Dim strline As String Dim array() As String Sub

我需要对数组进行数字排序。我将添加一个选项，供用户选择在按字母顺序排序后是否需要进一步排序。您拥有的基本上是一个包含多个数据类型的多维数组（但在您的示例中，您已将每一行连接到一个字符串中）。处理这种情况没有一个通盘的办法，但这里有一些方法可以考虑：
