I would like to create a multidimensional array of some description in VB.NET that can store and search the following data efficiently (search on the second dimension, to return the first).

CodePudding user response：

Dim data As New Dictionary(Of String, String) From {
    {"xls",  "excel"},
    {"xlsx", "excel"},
    {"doc",  "word"},
    {"docx", "word"},
    {"ppt",  "powerpoint"},
    {"pptx", "powerpoint"}
}

Access it like this:

Dim ext As String = "docx"
Dim folder As String = data(ext)
