C# &引用；无法执行查询错误"；在使用NHibernate的Web服务中

正如标题所说，我得到了这个错误：

无法执行查询
[选择此Id为Id5\u 0，此用户名为Username5\u 0，此密码哈希为Password3\u 5\u 0，此密码为Salt5\u 0，此令牌为Token5\u 0，此令牌为TokenStamp为TokenStamp5\u 0，此角色为Role5\u 0来自用户this”
中断时出错

我正在尝试在数据库中与用户进行简单登录，用户在数据库中键入用户名和密码散列。我有一个用户数据，每个列上都有Admin要调试

这是我的密码：

SQL Server数据库：

差不多就是这样。如果有人能帮忙，我将不胜感激……

User是sql中的保留字。您可以重命名您的表或让nhibernate在表名周围使用``我想如果您更改

Table("User"); 

到

它会起作用。

我认为这是正确的方法-“NHibernate在运行时用所选数据库方言的正确转义序列替换backticks“你看过所有内在的例外吗？大多数情况下，这将包含对实际错误的有用解释。您引用的异常文本只是NHibernate为真实错误信息提供额外上下文的方式。

using FluentNHibernate;
using FluentNHibernate.Conventions;

namespace NHibernate.Conventions
{
    public class CustomForeignKeyConvention : ForeignKeyConvention
    {
        protected override string GetKeyName(Member property, System.Type type)
        {
            if (property == null)
            {
                return type.Name;
            }

            return property.Name;
        }
    }
}

Table("User"); 

Table("`User`");
