正则表达式在数组中无法正常工作

Question

我希望能够搜索文件夹和子文件夹名称，然后如果它们的名称具有特定模式，请更改或从文件夹名称中删除它们。我使用了下面的代码但folderNameList返回{}string[] dirs = Directory.GetDirectories(myRootPath, "*", SearchOption.AllDirectories);string findFolderNamePattern = @"((?i)mydomain.com|sitename(?-i))";string replacement = " ";Match folderNameList = Regex.Match(dirs.ToString(), findFolderNamePattern);                foreach (var folder in folderNameList.ToString())                {                    folder = Regex.Replace(folder.ToString(), replacement);                }你也可以在这里看到正则表达式

Answer 1

您需要做的就是：

string[] directories = Directory.GetDirectories(myRootPath, "*", SearchOption.AllDirectories);

string findFolderNamePattern = @"((?i)mydomain.com|sitename(?-i))";

string replacement = " ";            

foreach (var directory in directories)

{

    var newFolder = Regex.Replace(directory, findFolderNamePattern, replacement);

}
