抱歉各位，看来我是傻了。我确实没有在输出路径中添加文件名。我不会删除这个问题，以防其他人被这个问题搞砸了！感谢所有的帮助/评论。

There are a few possibilities:
有几种可能：
- ConfigOutput is a folder
- ConfigOutput is a file that is in use (opened)
- You're not logged in as User 'Ash'
- ConfigOutput 是一个文件夹
- ConfigOutput 是一个正在使用（打开）的文件
- 您未以用户“Ash”身份登录
You should not normally have to run as Admin to write to your own Documents folder.
您通常不必以管理员身份运行来写入您自己的 Documents 文件夹。

Try run your app as administrator.
尝试以管理员身份运行您的应用程序。
If you want to debug your app, start your Visual Studio as administrator also.
如果你想调试你的应用程序，也以管理员身份启动你的 Visual Studio。
To force app start as administrator take a look at this thread: How do I force my .NET application to run as administrator?
要强制以管理员身份启动应用程序，请查看此线程： 如何强制我的 .NET 应用程序以管理员身份运行？
P.S. Check if your file is not already opened by another FileStream or etc.
PS 检查您的文件是否尚未被另一个 FileStream 等打开。

I don't know if this makes a difference, but you may want to specify the folder in a relative rather than absolute manner: Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments)will provide you with the path of the current user's documents. Check if it's different from the one you provide.
我不知道这是否有区别，但您可能希望以相对方式而不是绝对方式指定文件夹：Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments)将为您提供当前用户文档的路径。检查它是否与您提供的不同。
If so, you may need to run the app under a different user or administrator as others have pointed out. Obviously one user isn't allowed to just save files into another user's documents folder.
如果是这样，您可能需要像其他人指出的那样，在不同的用户或管理员下运行该应用程序。显然，不允许一个用户将文件保存到另一个用户的文档文件夹中。
For me when I debug my app from Visual Studio the documents folder is the same as the user I'm currently logged in as and running Visual Studio under.
对我来说，当我从 Visual Studio 调试我的应用程序时，文档文件夹与我当前登录并在其下运行 Visual Studio 的用户相同。
You could try <requestedExecutionLevel
level="asInvoker"
uiAccess="true|false"/>first and progressively move to highestAvailableand requireAdministrator.
您可以<requestedExecutionLevel
level="asInvoker"
uiAccess="true|false"/>先尝试并逐步移动到highestAvailable和requireAdministrator。
Alternatively, demand the permissions, catch the exception and print it out:
或者，请求权限，捕获异常并将其打印出来：
try {
FileIOPermission fileIOPermission = new FileIOPermission(FileIOPermissionAccess.AllAccess, myDocFolderFile);
fileIOPermission.Demand();
} catch (SecurityException se) {
Debug.WriteLine(se.ToString());
}

You need to check and get permission to that directory/file your writing.. for that
use Security namesapce
您需要检查并获得对该目录/文件的许可，以便使用 Security namesapce
var permissionSet = new PermissionSet(PermissionState.None);
var writePermission = new FileIOPermission(FileIOPermissionAccess.Write, pathToFolder);
permissionSet.AddPermission(writePermission);
if (permissionSet.IsSubsetOf(AppDomain.CurrentDomain.PermissionSet))
{
// do your stuff
}
else
{
// alternative stuff
}

It looks like you're not specifying a filename and therefore it can't create a file with the same name as an existing directory - so try changing your path to:
看起来您没有指定文件名，因此它无法创建与现有目录同名的文件 - 因此尝试将路径更改为：
C:\Users\Ash\Documents\ConfigOutput\Out.xml
C:\Users\Ash\Documents\ConfigOutput\Out.xml
