如何在c#中重命名文件

Consider:

I need to rename this file from add.gif to thumb1.gid, and I should write one command method, whatever the file name. We need to replace that name with this like below.

string strfilename = **"thumb"**

****Result thum.gif**

结果thum.gif * * * * * *

strPath= c:\images\gallery\thum.gif **

You have several problems, looking up the value in the XML file, and renaming the file.

您有几个问题，查找XML文件中的值，并重新命名文件。

To look up the number corresponding to Gallery2 or whatever, I would recommend having a look at Stack Overflow question How to implement a simple XPath lookup which explains how to look up nodes/values in an XML file.

要查找与Gallery2或其他相关的数字，我建议查看一下Stack Overflow问题，如何实现一个简单的XPath查找，它解释了如何在XML文件中查找节点/值。

To rename a file in .NET, use something like this:

要在。net中重命名文件，请使用以下方法:

using System.IO;

FileInfo fi = new FileInfo("c:\\images\\gallery\\add.gif");
if (fi.Exists)
{
    fi.MoveTo("c:\\images\\gallery\\thumb3.gif");
}

Of course, you would use string variables instead of string literals for the paths.

当然，您将使用字符串变量而不是字符串文本来代替路径。

That should give you enough information to piece it together and solve your particular lookup-rename problem.

这将为您提供足够的信息，使您能够将其组合在一起，并解决特定的查找重命名问题。
