使用Winforms / VB从Datatable构建分层Treeview [英] Hierarchical Treeview build from Datatable using Winforms / VB

问题描述

大家好，



我有一个SQL表（称为tblClosure），其中包含以下字段：

1.LocationID

2.LocationDesc

3.ParentID



我的问题是如何在winforms中填充此数据表中的树视图控件/ VB？我在c＃中看过一些例子，但我是一名新手编码器，我很难适应这些代码。



任何帮助都会非常感激。



理想情况下，我需要的是一个VB子程序来构建表中的TReeview层次结构。我已经看到这是C＃但我很难转换为VB。



提前谢谢

Hi All,

I have a SQL table (called tblClosure) which has these fields:
1.LocationID
2.LocationDesc
3.ParentID

My question is how can I populate a treeview control from this datatable in winforms/vb? I have seen examples in c# but I'm a rookie coder and am having difficulties adapting that code.

Any help would be greatly appreciated.

Ideally all I need is a VB sub to build the TReeview Hierarchy from the table. I have seen this is C# but am struggling to convert to VB.

Thanks in advance

推荐答案

如果您了解VB.NET而不是C＃，那么在实践中这是非常糟糕的。如果您需要帮助或寻找一些可用的代码示例，大多数最佳解决方案都在C＃中，而不是VB.NET，这些都经常不被认真对待。只是现实生活的事实。所以，你真的需要了解至少一些C＃。



至于翻译，它可以很容易地完成。在我过去的答案中，我提出了一些在线解决方案和一个非常好的全面的离线解决方案（开源ILSpy：它提供了出色的翻译结果，以及所有来源的即用型项目的形式代码文件）：

C＃到VB.NET的COde行解释 [ ^ ]，

需要将vb代码转换为c＃ [ ^ ]，

固定页面ContentPage将c＃代码转换为vb.net [ ^ ]，

源代码来自一个exe [ ^ ]。

If you understand VB.NET and not C#, this is pretty bad in practice. If you want help or look for some available code samples, the most of best solutions are in C#, not VB.NET, which are often is not taken seriously. Just the fact of real life. So, you really need to understand at least some of C#.

As to translation, it can be done easily enough. In my past answers, I suggested some on-line solutions and one really good and comprehensive off-line solution (open source ILSpy: it provides excellent translation results in no time, in the form of a ready-to-use project with all source code files):
COde Line Interpretatio of C# to VB.NET[^],
Need to convert vb code to c#[^],
FixedPage to ContentPage convert c# code into vb.net[^],
Source Code from a exe[^].
