Save edited XML Document to any location?
提问by KeyboardFriendly
In the below C# WPF code snippet, I want to load an XML document, edit the document, and save the output to a user designated location. I can use the XmlDocument.Savemethod to save to a pre-defined location, but how can I allow the user to save to any location like when choosing 'SaveAs'?
在下面的 C# WPF 代码片段中，我想加载一个 XML 文档，编辑该文档，并将输出保存到用户指定的位置。我可以使用该XmlDocument.Save方法保存到预定义的位置，但是如何允许用户保存到任何位置，例如选择“另存为”时？
XmlDocument doc = new XmlDocument();
doc.Load(@"C:\OriginalFile.xml");
doc.Save("File.xml");

see the code below; be aware that the UAC if the user select some system folder.
看下面的代码；请注意，如果用户选择了某个系统文件夹，则 UAC 将被禁用。
SaveFileDialog saveFileDialog = new SaveFileDialog();
saveFileDialog.Filter = "Xml (*.xml)|*.xml";
if (saveFileDialog.ShowDialog().Value)
{
doc.Save(saveFileDialog.FileName);
}

Use SaveFileDialog. Sample from the article:
使用SaveFileDialog。文章示例：
Microsoft.Win32.SaveFileDialog dlg = new Microsoft.Win32.SaveFileDialog();
dlg.FileName = "Document";
dlg.DefaultExt = ".xml";
dlg.Filter = "Xml documents (.xml)|*.xml"; // Filter files by extension
Nullable<bool> result = dlg.ShowDialog();
if (result == true)
{
// Save document
string filename = dlg.FileName;
}
