【基础巩固】文件流读写、大文件移动 FileStream StreamWriter File Path Directory/ ,m资料管理器（递归）
C#获取文件名 扩展名
string fullPath = @"d:\test\default.avi"; string filename = Path.GetFileName(fullPath);//返回带扩展名的文件名 "default.avi"
string extension = Path.GetExtension(fullPath);//扩展名 ".aspx"
string fileNameWithoutExtension = Path.GetFileNameWithoutExtension(fullPath);// 没有扩展名的文件名 "default" string dirPath = Path.GetDirectoryName(filePath) //返回文件所在目录 "d:\test"
string fullPath1 = Path.Combine(@"d:\test", "default.avi") //返回 "d:\test\default.avi" string fullPath2 = Path.GetFullPath("config.ini");//返回指定路径字符串的绝对路径
