我想要做的是从目录中获取所有文件名,并将它们输入到一维字符串Array中的单独索引中。下面的代码应该有用,我不明白我哪里出错了?
Public Sub RetrieveFilesAndPutinArray()
'Will be processed when Finish button is pressed.
'
Dim strArr As String() = Nothing ''Array <- i suspect declared the array wrong or something
Dim indexCounter = 0
'For each file:
For Each foundFile As String In My.Computer.FileSystem.GetFiles(
My.Computer.FileSystem.SpecialDirectories.MyDocuments)
'Add the file path and file name to the index position which is determined by: "IndexCounter"
strArr(indexCounter) = foundFile 'Array index is populated with string text of ^
'Then increment the index number by 1
indexCounter = indexCounter + 1
Next 'Repeat until all files have been processed.
For Count = 1 To (strArr.Length() - 1)
'Loop through all the files in the strArr Array and popup a msg box with the contents of the index number "Count"
MsgBox(strArr(Count))
Next
'Procedure complete.
'Can u see anything wrong? theoretically it should work now... how about asking StackOverflow.. get a quick resoponse.. should be
End Sub
答案 0 :(得分:1)
首先你必须Redim你的数组,然后你必须从0迭代到strArr.Length() - 1
Public Sub RetrieveFilesAndPutinArray()
'Will be processed when Finish button is pressed.
'
Dim strArr As String() = Nothing '' New String() ''Array <- i suspect declared the array wrong or something
Dim indexCounter = 0
Dim count As Integer = My.Computer.FileSystem.GetFiles(My.Computer.FileSystem.SpecialDirectories.MyDocuments).Count
ReDim strArr(count - 1)
'For each file:
For Each foundFile As String In My.Computer.FileSystem.GetFiles(My.Computer.FileSystem.SpecialDirectories.MyDocuments)
'Add the file path and file name to the index position which is determined by: "IndexCounter"
strArr(indexCounter) = foundFile 'Array index is populated with string text of ^
'Then increment the index number by 1
indexCounter = indexCounter + 1
Next 'Repeat until all files have been processed.
For count = 0 To (strArr.Length() - 1)
'Loop through all the files in the strArr Array and popup a msg box with the contents of the index number "Count"
MsgBox(strArr(count))
Next
'Procedure complete.

End Sub
