a problem with unzip a file

Mar 17, 2010 at 4:04 PM

hi, i'm new with this, and i have a problem with unzip a simple file. that's my code:


<font size="2" color="#0000ff"><font size="2" color="#0000ff">


</font></font><font size="2" color="#0000ff">




Public Class Unpack

Public shared Sub ExtraeZip(ByVal nomArch As String, ByVal dir As String)

Dim ZipToUnpack As String = nomArch

Dim TargetDir As String = dir

Console.WriteLine("Extracting file {0} to {1}", ZipToUnpack, TargetDir)

Using zip1 As ZipFile = ZipFile.Read(ZipToUnpack)

Dim e As ZipEntry

For Each e In zip1


Next <font size="2" color="#0000ff"><font size="2" color="#0000ff">

End Using

End Sub

End Class


that's sends me an error which says:

</font></font><font size="2" color="#0000ff">




Unable to load the file in the location ZipFile.cs c: \ dinoch \ dev \ dotnet \ zip \ DotNetZip \ Zip ......

I have to download another file than DotNetZip v1.9?

Can you show me an exception message, a stacktrace?

I don't understand the error you're getting.  It seems like it might be a message from your debugger, which is trying to load the source file shown in the .pdb file.  But that is not the primary problm, I suspect.

show me the stacktrace of the primary problem.

The exception comes from line 17 of your file Unpack.vb.

I don't know what that is, but I suspect it is this line:  Using zip1 As ZipFile = ZipFile.Read(ZipToUnpack)

The ZipToUnpack variable does not contain the name of a zip file.  It apparently contains the value "C:\Users\Manuel\Desktop\", which looks like a directory.
