Question

目标：

根据新数据更新表kund中行的当前和现有数据。新数据位于ContactInfo类中。

问题：

我检索了一条错误消息，上面写着＆＃34; No persister for：data_layer.ContactInfo＆＃34;。我尝试找到根问题，但我失败了。我不知道如何解决它。

信息：

不应用新数据行。
我正在使用Nhibernate，VS2013和SQL Server 2012
表格kund中的所有列都不会更新。要更新的列是用xml脚本编写的。

enter image description here

C＃代码：

public void Test(ContactInfo pMyContactInfo)
{
    using (var transaction = _session.BeginTransaction())
    {
        _session.SaveOrUpdate(pMyContactInfo);

        transaction.Commit();  
    }

}



namespace data_layer
{
    public class ContactInfo
    {
        public virtual int PK_kund { get; set; }
        public virtual string Kortnummer { get; set; }
        public virtual string Personnummer { get; set; }
        public virtual string Fornamn { get; set; }
        public virtual string Efternamn { get; set; }
        public virtual string Adress { get; set; }
        public virtual string Postnummer { get; set; }
        public virtual string Ort { get; set; }
        public virtual string Datum { get; set; }
        public virtual string Mobilnummer { get; set; }
        public virtual string Hemtelefon { get; set; }
        public virtual string Kon { get; set; }

    }
}

XML：

<?xml version="1.0" encoding="utf-8" ?>

  <class name="data_layer.ContactInfo,data_layer" table="Kund">

T-SQL：

Answer 1

检查您的xml文件是否以.hbm.xml结尾，并在Visual Studio中设置为嵌入式资源。

我敢打赌，这是你的问题;）

Answer 2

永远不要忘记.hbm.xml和嵌入式资源
