The fact that it's XML is basically irrelevant. You can save any text to a file very simply with File.WriteAllText:

它是XML的事实基本上是无关的。使用file . writealltext:

File.WriteAllText("foo.xml", xml);

Note that you can also specify the encoding, which defaults to UTF-8. So for example, if you want to write a file in plain ASCII:

注意，您还可以指定编码，默认为UTF-8。举个例子，如果你想用普通ASCII码写一个文件:

File.WriteAllText("foo.xml", xml, Encoding.ASCII);

#2

XmlDocument xdoc = new XmlDocument();
xdoc.LoadXml(yourXMLString);
xdoc.Save("myfilename.xml");

#3

If you don't need to do any processing on the string (with an XML library, for example), you could just do:

如果您不需要对字符串进行任何处理(例如使用XML库)，您可以这样做:

File.WriteAllText(@"c:\myXml.xml", xml);

#4

System.IO.File.WriteAllText("filename.xml", xml );

#5

You can do this:

你可以这样做:

string path = @"C:\testfolder\testfile.txt";

using (System.IO.StreamWriter file = new System.IO.StreamWriter(path))
{    
    file.Write(text);  
}

You can also do this after you've created an XML Document, but it is slower:

在创建了XML文档之后，您还可以这样做，但速度较慢:

xdoc.Save

#6

If you want to save the string as-is without performing any check on whether it's well-formed or valid, then as has been answered above, use System.IO.File.WriteAllText("C:\myfilename.xml", xml );

如果您想要保存该字符串，而不需要检查它是否格式良好或是否有效，那么如上所述，使用System.IO.File.WriteAllText(“C:\myfilename”。xml,xml);

As has also been noted, this defaults to saving the file as UTF-8, but you can specify encoding as Jon Skeet mentioned.

如前所述，默认情况下将文件保存为UTF-8，但是可以指定如Jon Skeet所提到的编码。

I'd recommend adding an XML declaration to the string, e.g.,

我建议在字符串中添加一个XML声明，例如，

<?xml version="1.0" encoding="UTF-8"?>

and ensuring the encoding in the declaration matches that in the WriteAllText method. It's likely to save a fair amount of hassle at later date, judging by the frequency of XML encoding questions on *.

并确保声明中的编码与WriteAllText方法中的编码匹配。从*的XML编码问题的频率来看，它很可能在以后节省大量的麻烦。

If you want to ensure the XML is well-formed and/or valid, then you will need to use an XML parser on it first, such as XDocument doc = XDocument.Parse(str); That method is also overridden if you want to preserve whitespace: XDocument.Parse(str, LoadOptions.PreserveWhitespace)

如果您希望确保XML格式良好和/或有效，则需要首先在其上使用XML解析器，例如XDocument doc = XDocument. parse (str);如果希望保留空格:XDocument，也可以重写该方法。LoadOptions.PreserveWhitespace Parse(str)

You can then perform validation on it http://msdn.microsoft.com/en-us/library/bb340331.aspx

然后可以对它执行验证http://msdn.microsoft.com/en-us/library/bb340331.aspx

before saving to file: doc.Save("C:\myfilename.xml");

保存文件前:doc.Save(“C:\myfilename.xml”);
