 EF更新指定字段.或个更新整个实体

 更新整个实体:
  public bool Update(Company compay)
         {
             if (compay != null)
             {
                 dbContext.Entry<Company>(compay).State = EntityState.Modified;
             }
             return this.SaveChanges() >  ? true : false;
         }

 更新指定字段:

  public bool Update( Entity.SoldTo soldModel, List<string[]> list)
         {
                 //更新
                 DbEntityEntry<Entity.SoldTo> uSoldModel = dbContext.Entry<Entity.SoldTo>(soldModel);
                 uSoldModel.State = System.Data.EntityState.Unchanged;

                 foreach (string Field in list[])
                 {
                     uSoldModel.Property(Field).IsModified = true;
                 }
             }
   return this.SaveChanges() >  ? true : false;
 }
