Handling Exceptions

Introduction to exceptions in UltimateZip

The exceptions that can be thrown by UltimateZip are handled in the same manner as regular runtime exception using Try/Catch blocks.

The following table provides a list of the custom exceptions that can be thrown when an error occurs:

Sample

Example below shows how to handle these exceptions:

using ComponentPro.Compression;
using System;

...

try
{
    // Create a new instance. 
    Zip zip = new Zip();
    // Create a new zip file. 
    zip.Create("test.zip");
    // Set password 
    zip.EncryptionAlgorithm = EncryptionAlgorithm.PkzipClassic;
    zip.Password = "password";

    // Add all files and subdirectories from 'c:\test' to the archive. 
    zip.AddFiles(@"c:\test");

    // Add all files and subdirectories from 'c:\my folder' to the archive. 
    zip.AddFiles(@"c:\my folder", "");

    // Add all files and subdirectories from 'c:\my folder' to '22' folder within the archive. 
    zip.AddFiles(@"c:\my folder2", "22");

    // Add all .dat files from 'c:\my folder' to '22' folder within the archive. 
    zip.AddFiles(@"c:\my folder2", "22", "*.dat");

    // Close the zip file. 
    zip.Close();
}
catch (ZipException exc)
{
    Console.WriteLine("Error: " + exc.Message);
}

Imports ComponentPro.Compression

Try 
    ' Create a new instance. 
    Dim zip As New Zip()
    ' Create a new zip file. 
    zip.Create("test.zip")
    ' Set password 
    zip.EncryptionAlgorithm = EncryptionAlgorithm.PkzipClassic
    zip.Password = "password" 
 
    ' Add all files and subdirectories from 'c:\test' to the archive. 
    zip.AddFiles("c:\test")

    ' Add all files and subdirectories from 'c:\my folder' to the archive. 
    zip.AddFiles("c:\my folder", "")

    ' Add all files and subdirectories from 'c:\my folder' to '22' folder within the archive. 
    zip.AddFiles("c:\my folder2", "22")

    ' Add all .dat files from 'c:\my folder' to '22' folder within the archive. 
    zip.AddFiles("c:\my folder2", "22", "*.dat")

    ' Close the zip file. 
    zip.Close()
Catch exc As ZipException
    Console.WriteLine("Error: " & exc.Message)
