通过局部类重命名LINQ 2 SQL实体属性 [英] Renaming LINQ 2 SQL Entity Properties Through Partial Classes

问题描述

我可以使用部分类创建指向L2S设计器生成的关联属性的属性.另外，我可以在查询中使用new属性吗?

Can I use partial classes to create properties that points to an association property generated by the L2S designer. Also, will I be able to use the new property in queries?

我该如何实现?

推荐答案

是的，但是您必须应用与linq2sql生成的属性相同的属性，即

Yes you can, but you have to apply the same attributes as the linq2sql generated property i.e.

    [Association(Name="Test_TestData", Storage="_TestDatas", ThisKey="SomeId", OtherKey="OtherId")]
    public System.Data.Linq.EntitySet<TestData> MyTestDatas
    {
        get
        {
            return this.TestDatas;
        }
    }

TestDatas是原始关系.

TestDatas being the original relation.

更新:我运行的示例查询:

Update: A sample query I ran:

        var context = new DataClasses1DataContext();
        var tests =
            from d in context.Tests
            where d.MyTestDatas.Any(md=>md.MyId == 2)
            select new
            {
                SomeId = d.SomeId,
                SomeData = d.SomeData,
                Tests = d.MyTestDatas
            };
        foreach (var test in tests)
        {
            var data = test.Tests.ToList();
        }
