Get Full Path of a File

The FullName property returns just the full path of a file including the file name. The following code snippet returns the full path of a file.

string fullFileName = fi.FullName;
Console.WriteLine("File Name: {0}", fullFileName);

Sample

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);
}
