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

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);}
