在VB.NET项目中嵌入和引用XML文件 [英] Embedding and referencing XML file in VB.NET project

问题描述

在VS2013 VB.NET WinForms项目中，我需要在已部署的应用程序中包含一个XML文件，该文件将在运行时读取和写入。

In a VS2013 VB.NET WinForms project I need to include an XML file in the deployed application that will be read from and written to at run time.

I将文件作为嵌入式资源，并选择始终复制作为输出。文件名为 Settings.xml，资源名称为设置。

I have the file as an embedded resource, and have "Copy Always" selected for output. The file name is "Settings.xml" and the resource name is Settings.

Looking at this example I did the following to reference it in my code:

Private xmlFile as XmlDocument ' In the general declaration area, before the Load event
xmlFile.LoadXml(My.Resources.Settings) ' In the Load event, in a Try/Catch

但是我在第二行收到对象引用未设置为对象的实例。

But I get an "Object reference not set to an instance of an object" on the second line.

在代码中，我计划使用以下方式访问xml：

In the code I plan on accessing the xml with something like this:

Dim xmlDoc as New XmlDocument
xmlDoc = xmlFile

我不确定如何保存任何更改使得，例如 xmlDoc.Save（xmlFile）之类的尝试不起作用。

I'm not sure yet how to save any changes I make, as initial attempts of something like xmlDoc.Save(xmlFile) didn't work.

我是什么

推荐答案

首先，您需要ed使用 xmlFile 的构造函数：

First of all, you need to use the constructor for xmlFile:

Private xmlFile As New XmlDocument

然后，您需要做的就是使用资源名称，即 Settings.xml嵌入资源：

Then, all you need to do is use the resource name, i.e. "Settings.xml" if the resource is embedded:

xmlFile.LoadXml("Settings.xml")

您甚至不需要将资源设置为 CopyAlways。

You shouldn't even need to set the resource as "CopyAlways".
