Question

我有一个文件，我们称之为“myFile.txt”，在一个文件夹中。在同一文件夹中还会有其他名为“myFile1.txt，myFile2.txt，myFile3.txt，myFile4.txt”的文件，依此类推。我想检查该文件夹并计算“myFile”在该文件夹中显示的次数，无论扩展名或“myFile”之后的数字。这是我到目前为止所拥有的，但它没有得到我想要的东西：

$("input[type='checkbox']:checked").prop("checked", true)

Answer 1

我掀起了这个并在Visual Studio中测试过它：

'Get a list of files from a directory you designate
    Dim counter As System.Collections.ObjectModel.ReadOnlyCollection(Of String)
    counter = My.Computer.FileSystem.GetFiles("C:\YOURDIR")

'Declare your file name
    Dim myfile As String = "YOURFILE"

'Create count dim
    Dim Occurrences As Integer = 0

'Check all files in the array and check them against our filename
    For Each File As String In counter
        If File.Contains(myfile) Then
'If a file is found, add +1
            Occurrences = Occurrences + 1
        End If
    Next
'Display total count
    MsgBox("number of files is " & Occurrences)

这将搜索您指定的路径。它将在dir中检查所有文件，如文件名。如果找到一个，它会计算它。这也会检查不区分大小写的名称，以便您可以获取文件名的所有变体。

如下所示：

Public Shared Sub ProcessDirectory(ByVal targetDirectory As String)
    Dim fileEntries As String() = Directory.GetFiles(targetDirectory)
    ' Process the list of files found in the directory.
    Dim fileName As String
    For Each fileName In fileEntries
        ' do a simple if statement to see if the file name contains "myFile"
        ' if so add to some count variable you declare
