我想要做的是从文件夹中的每个文件及其下方的所有文件夹中获取6个文件信息。这些作品是：
我有以下代码，它会吐出一个带路径的文件列表，但是我试图找出如何在输出中获取其他信息。如果它可以用分号或其他东西分隔，那将是好的，因为最终的愿望是将此信息写入表格。任何帮助表示赞赏。
private void GetMyFiles () {
string rootDirectory = @"" + txtPathToScan.Text + "";
string extension = "*";
List<string> files = GetFilesRecursively (rootDirectory, extension);
Console.WriteLine ("Got {0} files of extension {1} in directory {2}", files.Count, extension, rootDirectory);
foreach (string file in files) {
Console.WriteLine (file);
}
}
/// <summary>
/// This function calls itself recursively for each of the subdirectories that it finds
/// in the root directory passed to it. It returns files of the extension as specified
/// by the caller.
/// </summary>
/// <param name="rootDirectory">The directory from which the file list is sought.</param>
/// <param name="extension">The particular extension for which the file list is sought.</param>
/// <returns>A list of all the files with extension as specified by the caller. This list

static List<string> GetFilesRecursively (string rootDirectory, string extension) {
// Uncomment this line only if you want to trace the control as it goes from
// sub-directory to sub-directory. Be ready for long scrolls of text output:
//Console.WriteLine ("Currently in directory {0}", rootDirectory);
// Create an output list:
List<string> opList = new List<string> ();
// Get all files in the current directory:
string[] allFiles = Directory.GetFiles (rootDirectory, "*." + extension);
// Add these files to the output list:
opList.AddRange (allFiles);
// Get all sub-directories in current directory:
string[] subDirectories = Directory.GetDirectories (rootDirectory);
// And iterate through them:
foreach (string subDir in subDirectories) {
// Get all the files from the sub-directory:
List<string> subDirFileList = GetFilesRecursively (subDir, extension);
// And add it to this list:
opList.AddRange (subDirFileList);
}
// Finally return the output list:
return opList;
}

你可以使用FileInfo类......
var info = new System.IO.FileInfo(@"c:\folder\file.ext");
它具有Length，CreationTime，LastAccessTime和LastWriteTime的属性，可以将它们（例如）输出到控制台，您可以...
Console.WriteLine("For file {0}", info.Name);
Console.WriteLine("Length is {0}", info.Length);
Console.WriteLine("Creation time is {0}", info.CreationTime);
Console.WriteLine("Last access time is {0}", info.LastAccessTime);
Console.WriteLine("Last write time is {0}", info.LastWriteTime);
要获取完整文件名，您可以使用GetFileNameWithoutExtension ...
var fileName = System.IO.Path.GetFileNameWithoutExtension(@"c:\folder\file.ext")
filename将等于"file"。
获取文件扩展名的说明要多一些，但可以使用SHGetFIleInfo完成，有关详细信息，请参阅this answer。
要将其与您当前的代码集成（如果您不那么担心文件说明），可以更改GetFilesRecursively方法以返回List<FileInfo> ...
static List<FileInfo> GetFilesRecursively (string rootDirectory, string extension)
相应更新opList变量...
List<FileInfo> opList = new List<FileInfo> ();
然后调整AddRange来电添加FileInfo个对象......
opList.AddRange (allFiles.Select(f => new FileInfo(f)));
最后，subDirFileList的类型也需要更改，因此List<FileInfo>。
（我认为这就是一切！）
