获取文本文件的日期创建

Question

我在c＃中编写了一段代码来获取文本文件的创建日期并以yyyyMMddHHMMSS格式显示日期：

FileInfo fileInfo = new FileInfo("test.txt");
DateTime fileCreatedDate = fileInfo.CreationTime;
string dateCreation = fileCreatedDate.ToString("yyyyMMddHHMMSS");

但它不起作用，dateCreation例如：201401291001SS

我该如何修改？

Answer 1

您有大写分钟，即月份，请改为使用mm（和ss）：

string dateCreation = fileCreatedDate.ToString("yyyyMMddHHmmss");

Answer 2

试试这个

MM指的是两位数的月份

mm指两位数分钟

FileInfo fileInfo = new FileInfo("test.txt");
DateTime fileCreatedDate = fileInfo.CreationTime;
string dateCreation = fileCreatedDate.ToString("yyyyMMddHHmmss");

Answer 3

看看这一行：

FileInfo fileInfo = new FileInfo("test.txt");

我想你忘了添加你的路径。请参阅以下示例：

 string path = @"yourpath\test.txt";
 FileInfo fileInfo = new FileInfo(path);

然后：

string dateCreation = fileCreatedDate.ToString("yyyyMMddHHmmss");

Answer 4

//Take a file 
DateTime creationTime = File.GetCreationTime(@"C:\CC.txt");
//Print
Response.Write(creationTime.ToString("yyyyMMddHHmmss")); 

Answer 5

FileInfo fileInfo = new FileInfo("test.txt");
DateTime fileCreatedDate = fileInfo.CreationTime;
string date = fileCreatedDate.ToString("yyyyMMddHHmmss");
