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() > 0 ? 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[0])
                {
                    uSoldModel.Property(Field).IsModified = true;
                }
            }
  return this.SaveChanges() > 0 ? true : false;
}
