Question

在我保存XDocument的旧项目中，Save函数有7个重载，包括＆＃34;字符串fileName＆＃34;

现在在使用Net Core的新项目中，没有超载接受应该保存文档的字符串。

我有这个：

XDocument file = new XDocument();
XElement email = new XElement("Email");
XElement recipientsXml = new XElement("Recipients");
foreach (var r in recipients)
{
   var rec = new XElement("Recipient",
       new XAttribute("To", r));
   recipientsXml.Add(rec);
}
email.Add(recipientsXml);
file.Add(email);
file.Save(@"C:\1\email.xml");

如何将XDocument保存在磁盘中？

感谢。

您可以像这样保存XDocument，但需要添加一些SaveOptions（implementation）。看看Implementation of XDocument：

public void Save(string fileName, SaveOptions options)
{
    XmlWriterSettings ws = GetXmlWriterSettings(options);
    if (_declaration != null && !string.IsNullOrEmpty(_declaration.Encoding))
    {
        try
        {
            ws.Encoding = Encoding.GetEncoding(_declaration.Encoding);
        }
        catch (ArgumentException)
        {
        }
    }

    using (XmlWriter w = XmlWriter.Create(fileName, ws))
    {
        Save(w);
    }
}

您可以使用编写器实现自己的解决方案，或者只需调用现有方法，如

file.Save(@"C:\1\email.xml", SaveOptions.None);

好的，我发现了怎么做。

FileStream fileStream = new FileStream(@"C:\1\emails.xml");
XmlWriterSettings settings = new XmlWriterSettings() { Indent = true };
XmlWriter writer = XmlWriter.Create(fileStream, settings);

XDocument file = new XDocument();
XElement email = new XElement("Email");
XElement recipientsXml = new XElement("Recipients");
foreach (var r in recipients)
{
   var rec = new XElement("Recipient",
       new XAttribute("To", r));
   recipientsXml.Add(rec);
}
email.Add(recipientsXml);
file.Add(email);
file.Save(writer);

writer.Flush();
fileStream.Flush();

netDore中不存在XDocument Save String参数
