Answer 2

Hi how about creating a method just for this:

private static void CreateXMLFile(string xml, string filePath)
    {
        // Create the XmlDocument.
        XmlDocument doc = new XmlDocument();
        doc.LoadXml(xml); //Your string here

        // Save the document to a file and auto-indent the output.
        XmlTextWriter writer = new XmlTextWriter(filePath, null);
        writer.Formatting = Formatting.Indented;
        doc.Save(writer);
    }

如果您唯一要做的就是将字符串另存为文件（并且您不想执行XML特定的工作，例如检查格式正确或自动缩进），则只需使用File.WriteAllText() 。
