How to check when a File was created in C#

​The File.CreationTime property returns the DateTime when a file was created. The following code snippet returns the creation time of a file.

// Creation, last access, and last write time   
DateTime creationTime = fi.CreationTime;  
Console.WriteLine("Creation time: {0}", creationTime); 

Code Example

Here is a complete sample.

// Full file name     
string fileName = @"/Users/praveen/Desktop/images\November.pdf";  
FileInfo fi = new FileInfo(fileName);  
  
// Create a new file   
using (FileStream fs = fi.Create())  
{  
    Byte[] txt = new UTF8Encoding(true).GetBytes("New file.");  
    fs.Write(txt, 0, txt.Length);  
    Byte[] author = new UTF8Encoding(true).GetBytes("Author Mahesh Chand");  
    fs.Write(author, 0, author.Length);  
}  
  
// Get File Name  
string justFileName = fi.Name;  
Console.WriteLine("File Name: {0}", justFileName);  
// Get file name with full path   
string fullFileName = fi.FullName;  
Console.WriteLine("File Name: {0}", fullFileName);  
// Get file extension   
string extn = fi.Extension;  
Console.WriteLine("File Extension: {0}", extn);  
// Get directory name   
string directoryName = fi.DirectoryName;  
Console.WriteLine("Directory Name: {0}", directoryName);  
// File Exists ?  
bool exists = fi.Exists;  
Console.WriteLine("File Exists: {0}", exists);  
if (fi.Exists)  
{  
    // Get file size  
    long size = fi.Length;  
    Console.WriteLine("File Size in Bytes: {0}", size);  
    // File ReadOnly ?  
    bool IsReadOnly = fi.IsReadOnly;  
    Console.WriteLine("Is ReadOnly: {0}", IsReadOnly);  
    // Creation, last access, and last write time   
    DateTime creationTime = fi.CreationTime;  
    Console.WriteLine("Creation time: {0}", creationTime);  
    DateTime accessTime = fi.LastAccessTime;  
    Console.WriteLine("Last access time: {0}", accessTime);  
    DateTime updatedTime = fi.LastWriteTime;  
    Console.WriteLine("Last write time: {0}", updatedTime);  
}
