推荐答案

既然你知道你要搜索的根目录和文件名字符串模式，您可以创建一个DirectoryInfo中与根目录：

Since you know the root directory you want to search and a string pattern for a filename, you can create a DirectoryInfo with the root directory:

DirectoryInfo dir = new DirectoryInfo(@"E:\");

然后调用的GetFiles（）来获得所有的比赛。 。通过 SearchOption.AllDirectories 将确保搜索是递归的

And then call GetFiles() to get all the matches. Passing SearchOption.AllDirectories will ensure the search is recursive.

List<FileInfo> matches = 
    new List<FileInfo>(dir.GetFiles(partialFilename, 
        SearchOption.AllDirectories));

或者，如果你知道路径（而不是文件名）的一部分：

Or if you know part of the path (instead of the filename):

List<DirectoryInfo> matches =
    new List<DirectoryInfo>(dir.GetDirectories(partialDirectoryName,
        SearchOption.AllDirectories));

然后你就可以从那里导航到该文件。

And then you can navigate to the file from there.
