我的XML文档不会保存对该文档所做的更改 [英] My XML document will not save changes made to the document

问题描述

大家好，

我正在构建一个应用程序，该应用程序将允许我的用户更改其密码.他们的密码将存储在XML文档中.另外，我计划根据存储在XML文档中的秘密问题进行密码重置.我的代码逐步没有 错误，但XML文档保持不变.

I am building an application that will allow my user to change their password. Their password will be stored in an XML Document. Also, I plan on doing password reset based off of secret questions, stored in an XML document. My code steps-through without error, but the XML document remains unchanged.

在XML文件的属性中，我尝试将复制到输出"设置为作为始终复制"和如果较新则复制"，没有运气.

In my properties for the XML file, I have tried to set "Copy to output" as "Copy Always", and "Copy if Newer", no luck.

我的保存代码如下:

XmlDocument XMLdoc = new XmlDocument();
                string XMLfilename = "PasswordHoldDoc.xml";
                XMLdoc.Load(XMLfilename);
                XmlNode root = XMLdoc.DocumentElement;
                String pwdNode = root.FirstChild.InnerText;
                //XmlNode pwdNode = XMLdoc.SelectSingleNode("/directory/password");
                if (pwdNode != null)
                {
                    root.FirstChild.InnerText = passwordConfirmTextbox.Text;
                   
                    XMLdoc.Save("PasswordHoldDoc.xml");
                    MessageBox.Show("done!");

推荐答案

您未设置保存位置，因此它将与执行程序集保存在同一文件夹中，可能是bin/debug.如果您将其设置为复制到输出，则每次构建时都可能会覆盖它.

You do not set a save location, so it will save in the same folder as the executing assembly, probably bin/debug. If you have it set to copy to output then it is probably overwriting it everytime you build. 

请尝试保存到其他文件夹，以查看您的代码是否还能正常工作.类似于c:\ testfolder \ PasswordHold.xml".

Try saving to a different folder, just to see if you code is even working. Something like c:\testfolder\PasswordHold.xml".

最后，System.Xml.Linq命名空间中的XDocument比XMLDocument更易于使用，并且是更受欢迎的命名空间.

Lastly, XDocument, in the System.Xml.Linq namespace is easier to use and a more preferred namespace than XMLDocument.
