Question: I want to import the Sitecore packages in Sitecore through code. Is there way to do this?

Answer: 
Your question did not specify which language the code needed to be written in, so here is an example in PowerShell.

```
PS master:\> Install-Package -Path YourPackageName.zip -InstallMode Merge -MergeMode Merge

```

Unless you have a really good reason to use C# code to install the packages, I would recommend you use Sitecore PowerShell Extensions (SPE).

Check out the book for more details:
<https://doc.sitecorepowershell.com/appendix/commands/Install-Package.html>
You can use Sitecore API to import the packages. You can use the code like

```
using (new ProxyDisabler())  
    {  
        using (new SyncOperationContext())  
        {  
            IProcessingContext context = new SimpleProcessingContext();  
            IItemInstallerEvents events = new DefaultItemInstallerEvents(new BehaviourOptions(InstallMode.Overwrite, MergeMode.Undefined));  
            context.AddAspect(events);  
            IFileInstallerEvents events1 = new DefaultFileInstallerEvents(true);  
            context.AddAspect(events1);  

            Sitecore.Install.Installer packageInstaller = new Sitecore.Install.Installer();  
            packageInstaller.InstallPackage(MainUtil.MapPath("exact path for package with file name"), context);  
        }  
    }  
}  

```

Additionally you can use Sitecore API to export the package also.
