            MultilistField multilistField = Sitecore.Context.Item.Fields["your_field_name"];
            if (multilistField != null)
            {
                var items = multilistField.TargetIDs.Select(id => Sitecore.Context.Database.GetItem(id)).Where(id => id != null);
                //use items
            }

2. Dynamically assign images to the sitecore items from media library

private void AssignImageFromMediaLibrary(string sitecoreImagepath, Item itm, string fieldName)
        {
            string error = string.Empty;
            try
            {
                Sitecore.Data.Fields.ImageField imageField = itm.Fields[fieldName];
                if (!String.IsNullOrEmpty(sitecoreImagepath))
                {                   
                    sitecoreImagepath= sitecoreImagepath.Replace(".jpg", "");
                    sitecoreImagepath= sitecoreImagepath.Replace(".JPG", "");
                    sitecoreImagepath= sitecoreImagepath.Replace(".png", "");
                    sitecoreImagepath= sitecoreImagepath.Replace(".gif", "");
                    sitecoreImagepath= sitecoreImagepath.Replace("%20", " ");
                    error = sitecoreImagepath;
                    Sitecore.Data.Items.MediaItem medialImage = new Sitecore.Data.Items.MediaItem(currentDB.GetItem(sitecoreImagepath));
                   
                    imageField.Alt = medialImage.Alt;
                    imageField.MediaID = medialImage.ID;
                    imageField.Src = MediaManager.GetMediaUrl(medialImage);
                    imageField.MediaPath = medialImage.MediaPath;
                }
                else
                {
                   
                    imageField.Src = "";
                    imageField.MediaPath = "";
                }
            }
            catch (Exception ex)
            {
                lblerror.Text = "Error:--  " + error;
                lblerror.ForeColor = System.Drawing.Color.Red;
            }
        }
3. Creating language version to sitecore item

 private Item CreateVersion(Item itm string languageCode)
        {
            Item destinationLanguageItem = currentDB.GetItem(itm.ID, Sitecore.Globalization.Language.Parse("languageCode)"));  //Language code example : de-DE
            destinationLanguageItem.Versions.AddVersion();
            return destinationLanguageItem;           
        }
4. How to select sitecore items in mulitlist from code behind
   private void SelectMultiListItemColletions(string itemIDs, Item itm, string fieldName)

           appMultilist.Value = itemIDs;//itemIDs are sapeated with pipe symbol "|"
        }
5. Sitecore Fallback Language 

Private void FallbackLanguage(string langCode)
{
       Sitecore.Globalization.Language fallbackLang = Sitecore.Globalization.Language.Parse("en-EN");
                Sitecore.Globalization.Language setLang = Sitecore.Globalization.Language.Parse(langCode));
                Item contextItem = Sitecore.Context.Item;
                LanguageCollection collection = ItemManager.GetContentLanguages(contextItem);
               
     bool isLanguageExist = false;
              
                for (int i = 0; i < collection.Count; i++)
                {                   
                    var itm = Sitecore.Context.Database.GetItem(Sitecore.Context.Item.ID, collection[i]);
                    if (setLang == collection[i])
                    {
                        if (itm.Versions.Count > 0)
                        {                      
                            isLanguageExist = true;
                        }
                    }
                }
                if (isLanguageExist)
                {
                    Sitecore.Context.SetLanguage(setLang, true);             
                }
                else
                {
                    Sitecore.Context.SetLanguage(fallbackLang, true);
                }
                Response.Redirect(Sitecore.Links.LinkManager.GetItemUrl(Sitecore.Context.Item));
