精确的文件扩展名与GetFiles（）匹配？
我想检索一个扩展名与指定字符串完全匹配的文件列表。
DirectoryInfo di = new DirectoryInfo(someValidPath);
List<FileInfo> myFiles = new List<FileInfo>();
foreach (FileInfo fi in di.GetFiles("*.txt"))
{
myFiles.Add(fi);
}
*.txt
*.txtx
txt
"\.txt$"
.EndsWith(".txt")没有找到相关结果

extesion方法过滤掉完全匹配：foreach (FileInfo fi in di.GetFiles("*.txt") .Where(fi => string.Compare(".txt", fi.Extension, StringComparison.OrdinalIgnoreCase) == 0)) { myFiles.Add(fi); }鲁釜头
var list = di.GetFiles("*.txt").Where(f => f.Extension == ".txt"); myFiles.AddRange(list);List<FileInfo> myFiles = di.GetFiles("*.txt").Where(f => f.Extension == ".txt").ToList();俯乡骚钵皆
foreach (FileInfo fi in di.GetFiles("*.txt").Where(f => f.Extension == ".txt")) { myFiles.Add(fi); }河饶办斜施
DirectoryInfo di = new DirectoryInfo(someValidPath); List<FileInfo> myFiles = ( from file in di.GetFiles("*.txt") where file.Extension == ".txt" select file ).ToList();悸翠疮武昏
DirectoryInfo di = new DirectoryInfo(someValidPath); List<FileInfo> myFiles = new List<FileInfo>(); foreach (FileInfo fi in di.GetFiles("*.txt")) { if (fi.Extension == ".txt") myFiles.Add(fi); }浆错
梦砍废么
string fileExtensionFilter = "*.txt"; DirectoryInfo di = new DirectoryInfo(Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments)); List<FileInfo> myFiles = new List<FileInfo>(); foreach (FileInfo fi in di.GetFiles(fileExtensionFilter)) { if (fi.Extension == fileExtensionFilter.Substring(1)) myFiles.Add(fi); }拈吉勉犬姆
public string[] GetFiles(string path, string pattern) { bool lastWildIsHook = false; if(pattern.EndsWith("?")) { pattern = pattern.Substring(0, pattern.Length - 1); lastWildIsHook = true; } var lastWildIndex = Math.Max(pattern.LastIndexOf("*"), pattern.LastIndexOf("?")); var endsWith = pattern.Length > lastWildIndex ? pattern.Substring(lastWildIndex + 1) : pattern; if(!lastWildIsHook) return Directory.GetFiles(path, pattern).Where(p => p.EndsWith(endsWith)).ToArray(); else return Directory.GetFiles(path, pattern).Where(p => p.EndsWith(endsWith) || p.Substring(0, p.Length - 1).EndsWith(endsWith)).ToArray(); }
