The name 'zipfile' does not exist in the current context

Question

I have an SSIS project that I can run as is, but when I try to edit it, I get an error:

The name 'zipfile' does not exist in the current context

Without editing, it works fine.

The code that's producing the error:

public void Main()
{
    // TODO: Add your code here
    string moduleName = Dts.Variables["User::ModuleName"].Value.ToString();
    string s = Dts.Variables["User::ZipFileLocation"].Value.ToString().TrimEnd('\\') + "\\" + moduleName + "\\" + moduleName + "_" + DateTime.Now.ToString("ddMMyyyy");

    // TODO: Add your code here
    string startPath = s;
    string zipPath = s + ".zip";

    try
    {
        File.Delete(zipPath);
        ZipFile.CreateFromDirectory(startPath, zipPath);
    }
    catch (Exception e)
    {
    }

    Dts.TaskResult = (int)ScriptResults.Success;
}

How can I solve this?

Answer 1

Make sure you are using .NET version 4.5. Reference the Compression DLL - here is the path:

C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5\System.IO.Compression.FileSystem.dll

Reference it in the class by adding using System.IO.Compression.FileSystem. If the class is inherited from another class, make sure to reference it in the parent class too. (This is what I have to do to make it compile)

Answer 2

To use the ZipFile class, you must add a reference to the System.IO.Compression.FileSystem assembly in your project; otherwise, you'll get the following error message when trying to compile:

The name 'ZipFile' does not exist in the current context.
