我正在编写一个将XML数据映射到数据库表的程序。
这是我尝试的方式：

Test();
}

错误说

为什么我会收到错误？
最重要的是，我怎样才能翻译＆＃34;用于匹配表列的XML标记？
答案 0 :(得分：0)
您没有通过所有字段。您必须为其余部分添加参数。
command1.Parameters.AddWithValue("@NationalRegistrationNotifyDistributionAddress", yourData);
// same for the rest fields
此外，在第一个参数之后，sql中缺少@。
答案 1 :(得分：0)
在你的长代码行中找到
at第一个是 values(@PersonalIdentityNumber, NationalRegistrationNotifyDistribution ...
，第二个不是。
您必须知道使用列名称的位置以及使用变量名称的位置。
您可以在@中使用文字值，但是 - 如果您使用参数（使用VALUES，您必须声明所有，并在命令中添加值对象。出于测试目的，您只需添加以下内容：
@使用文字值进行测试或添加所有参数并使用command1.Parameters.AddWithValue("@PersonalIdentityNumber", ...
正确命名
答案 2 :(得分：0)
也许尝试用所有XML内容编写序列化类，然后反序列化它（将XML读入类中）。最好是使用XML具有内部节点的内部类，而不仅仅是平面XML。
我认为这只是一次尝试，所以下一个训练点可能是分裂单个怪物＆＃34; DB中的表进入逻辑链接单元（又称规范化）。
