Hi,

I am writing a function to unzip a zipped file. But I'm getting this error, "Cast from string "C:\temp\FileName.zip" to type 'Integer' is not valid." Below is my coding, I got this error in the bold line. May I know what does the casting error mean here? Why do I need to cast the string of my zip file path to integer?

ExtractZIPfiles(Directory.GetFiles(strFullDirectoryPath, "*.Zip"))


Private Sub ExtractZIPfiles(ByVal pathList() As String)
        Dim x As New ICSharpCode.SharpZipLib.Zip.FastZip
        Dim strFullDirectoryPath As String = Path.GetFullPath("C:\temp")

        For Each s As String In pathList

           [B] x.ExtractZip(pathList(s), strFullDirectoryPath, "csv;xsl")[/B]

        Next
End Sub

Private Sub ExtractZIPfiles(ByVal pathList() As String)
Dim x As New ICSharpCode.SharpZipLib.Zip.FastZip
Dim strFullDirectoryPath As String = Path.GetFullPath("C:\temp")

For Each s As String In pathList

x.ExtractZip(pathList(s), strFullDirectoryPath, "csv;xsl")

Next
End Sub
hi,
above function's return type may be an integer so u need to declare one variable as integer and rewrite it again as like follows
dim y as int
y=x.ExtractZip(pathList(s), strFullDirectoryPath, "csv;xsl")
it will be execute properly

Private Sub ExtractZIPfiles(ByVal pathList() As String)
Dim x As New ICSharpCode.SharpZipLib.Zip.FastZip
Dim strFullDirectoryPath As String = Path.GetFullPath("C:\temp")

For Each s As String In pathList

x.ExtractZip(pathList(s), strFullDirectoryPath, "csv;xsl")

Hi,

I've tried your suggestion, it cannot work, because it says the expression

[B]x.ExtractZip(pathList(s), strFullDirectoryPath, "csv;xsl")
[/B]

does not return a value. :(

So anymore suggestion?

This pathList(s) is evaluated before the ExtractZip method, pathList is an array and requires an integer argument in the parenthesis representing the index number, but string s is being passed instead.
