自动赋值方法CloneObjectData<SourceType, CloneType>-atnet类库

使用场景:在两个有相同属性的类之间拷贝数据，bool ignoreNullValue参数可选是否忽略空值拷贝

方法定义:

/// <summary>
        /// 拷贝对象的数据
        /// </summary>
        /// <param name="s">包含数据的对象</param>
        /// <param name="c">要拷贝数据的对象</param>
<br>        /// <param name="ignoreNullValue">是否忽略空值</param>       public static void CloneObjectData<SourceType, CloneType>(SourceType s, CloneType c,bool ignoreNullValue);

使用范例:

using Atnet.Data;
    
public static void GetCustomProfile(Account account)
        {
            pa_AccountInfoControl p = new pa_AccountInfoControl { AccountName = account.AccountName };
            p.ExecuteNonQuery();
            DataHelper.CloneObjectData<pa_AccountInfoControl, Account>(p, account, false);
        }
 
        public static void UpdateCustomProfile(Account account)
        {
            pa_AccountInfoControl p = new pa_AccountInfoControl();
            DataHelper.CloneObjectData<Account,pa_AccountInfoControl>(account, p, false); 
            p.ExecuteNonQuery();
        }

pa_AccountInfoControl为代码生成器生成的存储过程类,Account为一个实体类,方法实现了更新和获得数据!
