Question

我确定这很简单，但遗憾的是，我也是。这是我的班级：

private List<string> colDescNode = new List<string>();

public List<string> ColDescNode
{
    get { return colDescNode; }
    set { colDescNode = value; } 
}

public TreeViewColorDescNodes()
{
    List<string> colDescNode = new List<string>();
    connect.Open();

    using (SqlCommand cmd = new SqlCommand("RMM3DMTagColors", connect))
    {
        cmd.CommandType = CommandType.StoredProcedure;
        using (SqlDataReader drReader = cmd.ExecuteReader())
        {
            while (drReader.Read())
            {
                if (!drReader.IsDBNull(0))
                    colDescNode.Add(drReader.GetString(0));
            }
        }
    }
}

}

到目前为止，这是我的表格。我已经查看了其他问题，但无法找到我理解的答案。在这一点上，一切都远远超出了我的技能水平。

public void fillTreeViewByList()
{
    connect.Open();

    TreeViewColorDescNodes firstNode = new TreeViewColorDescNodes();  // Everything from here down is probably wrong...

    tvDiscountMaintenance.Nodes.Add("Select All"); 
    foreach (var item in ColDescNode)
    {
        TreeNode colorDesc = new TreeNode(ColDescNode.ToString());
        tvDiscountMaintenance.Nodes[0].Nodes.Add(item.ToString());  
    }
}

我试图填写Treeview，但这是一组完全不同的问题。任何帮助是极大的赞赏。谢谢。

请尝试以下操作。我使用记事本编辑代码，所以请原谅任何语法错误

Traceback (most recent call last):
  File "C:\Python35\lib\site-packages\tensorflow\python\framework\tensor_shape.py", line 451, in __init__
    dims_iter = iter(dims)
  File "C:\Python35\lib\site-packages\tensorflow\python\framework\ops.py", line 510, in __iter__
    raise TypeError("'Tensor' object is not iterable.")
TypeError: 'Tensor' object is not iterable.

During handling of the above exception, another exception occurred:
