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:

        /// <param name="ignoreNullValue">是否忽略空值</param>

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!
