using (ZipFile zip = new ZipFile()
{
    zip.Password = "password";
    zip.AddDirectory(path);
    zip.Save(outputPath);
}

I with using this code zip file my directory or file. but i want set password in my zip file.

So, I using this code:

using (ZipFile zip = new ZipFile("MyFile.zip")
{
    zip.Password = "password";
    zip.Save();
}

The following is a sample code for file encyption. Hope this will solve your problem.

// create a file with encryption
using (ZipFile zip = new ZipFile())
{
    zip.AddFile("ReadMe.txt");
    zip.Password= "!Secret1";
    zip.AddFile("MapToTheSite-7440-N49th.png");
    zip.AddFile("2008-Regional-Sales-Report.pdf");
    zip.Save("EncryptedArchive.zip");
}

// extract entries that use encryption
using (ZipFile zip = ZipFile.Read("EncryptedArchive.zip"))
{
    zip.Password= "!Secret1";
    zip.ExtractAll("extractDir");
}
