System.Data.Linq.Mapping 命名空间包含用于生成表示关系数据库的结构和内容的 LINQ to SQL 对象模型的类

[Table(Name="Employees")]
public class Employees
{
    private string _LastName;    
    // …
    [Column(Storage="_LastName", DbType="NVarChar(20) NOT NULL", 
        CanBeNull=false)]
    public string LastName
    {
        get
        {
            return this._LastName;
        }
        set
        {
            if ((this._LastName != value))
            {
                this.OnPropertyChanging("LastName");
                this._LastName = value;
                this.OnPropertyChanged("LastName");
            }
        }
    }
