.net - RDLC(VS 2010)如何访问DataObjects上的嵌套类或数组

Question

如何在RDLC上访问TD.SubNumber属性和Numbers []？我在表达式“= Fields!TD.Value.SubNumber”和“= Fields!Numbers.Value(0)”上不断遇到#Error。

public class TestData
{

    TestSubData tdata = new TestSubData();
    public TestSubData TD
    {
        get { return tdata; }
        set { tdata = value; }
    }

    string m_Description;
    public string Description
    {
        get { return m_Description; }
        set { m_Description = value; }
    }

    int[] m_Numbers = new int[12];
    public int?[] Numbers
    {
        get { return m_Numbers; }
    }


}
public class TestSubData
{
    int x;
    public TestSubData()
    { 
    }

    public int SubNumber
    {
        get { return x; }
        set { x = value; }
    }
}

将“serializable”属性添加到每个嵌套类中，然后可以使用以下表达式引用:

“= Fields!TD.Value.SubNumber”

[Serializable()]
public class TestData
{
    TestSubData tdata = new TestSubData();
    public TestSubData TD
    {
        get { return tdata; }
        set { tdata = value; }
    }

    string m_Description;
    public string Description
    {
        get { return m_Description; }
        set { m_Description = value; }
    }

    int[] m_Numbers = new int[12];
    public int?[] Numbers
    {
        get { return m_Numbers; }
    }
}

[Serializable()]
public class TestSubData
{
    int x;
    public TestSubData()
    { 
    }

    public int SubNumber
    {
        get { return x; }
        set { x = value; }
    }
}
