接口类：
/// <summary> /// 更新指定字段 /// </summary> /// <param name="entity">实体</param> /// <param name="fileds">更新字段数组</param> void UpdateEntityFields(T entity, List<string> fileds);
实现接口类：
public void UpdateEntityFields(T entity, List<string> fileds)
{
if (entity != null&&fileds!=null)
{
dbContext.CreateObjectSet<T>().Attach(entity);
var SetEntry = ((IObjectContextAdapter)dbContext).ObjectContext.
ObjectStateManager.GetObjectStateEntry(entity);
foreach (var t in fileds)
{
SetEntry.SetModifiedProperty(t);
}
}
}
