我如何检查，看看是否两个XML文件是在C＃中的一样吗？

How do I check to see if two XML files are the same in C#?

我想忽略在XML文件中的注释。

I want to ignore comments in the XML file.

推荐答案

安装免费的 XMLDiffMerge套餐的NuGet 。这个包在本质上是 XML差异和微软补丁GUI工具的重新包装版。

Install the free XMLDiffMerge package from NuGet. This package is essentially a repackaged version of the XML Diff and Patch GUI Tool from Microsoft.

这个函数返回真如果两个XML文件是相同的，忽略的意见，白色的空间，和子序列。作为奖励，它也可以出差异（见的差异在函数内部变量）。

This function returns true if two XML files are identical, ignoring comments, white space, and child order. As a bonus, it also works out the differences (see the internal variable differences in the function).

/// <summary>
/// Compares two XML files to see if they are the same.
/// </summary>
/// <returns>Returns true if two XML files are functionally identical, ignoring comments, white space, and child
/// order.</returns>
public static bool XMLfilesIdentical(string originalFile, string finalFile)
{
    var xmldiff = new XmlDiff();
    var r1 = XmlReader.Create(new StringReader(originalFile));
    var r2 = XmlReader.Create(new StringReader(finalFile));
    var sw = new StringWriter();
    var xw = new XmlTextWriter(sw) { Formatting = Formatting.Indented };

    xmldiff.Options = XmlDiffOptions.IgnorePI | 
        XmlDiffOptions.IgnoreChildOrder | 
        XmlDiffOptions.IgnoreComments |
        XmlDiffOptions.IgnoreWhitespace;
    bool areIdentical = xmldiff.Compare(r1, r2, xw);

    string differences = sw.ToString();

    return areIdentical;
}   

下面是我们如何调用该函数：

Here is how we call the function:

string textLocal = File.ReadAllText(@"C:\file1.xml");
string textRemote = File.ReadAllText(@"C:\file2.xml");
if (XMLfilesIdentical(textLocal, textRemote) == true)
{
    Console.WriteLine("XML files are functionally identical (ignoring comments).")
}
