如何在运行时更改LINQ O/RM表名/源？

public class CustomDataContext : DataContext
{
    public CustomDataContext(string connectionString) : base(connectionString) { }

    public Table<YourEntity> YourEntities;
}

protected override void OnCreated()
{
    base.OnCreated();

    // 更改表名或数据源
    this.GetTable<YourEntity>().Expression =
        this.GetTable<YourEntity>().Expression.Replace("YourEntities", "NewTableName");
}

using (var context = new CustomDataContext(connectionString))
{
    var query = from entity in context.YourEntities
                where entity.SomeProperty == someValue
                select entity;

    // 执行查询并处理结果
}
