Hi, i'm new in this and need help on C#.
How can i get the Versions of applications.
I have desktop app  and i  create label.
Now i want that my label will show current versions of programs on computer.
lets say :
Skype: - version -
Notepad++ :  - version
Chrome :    -version 
If i can just tell C:\Program Files\Notepad++\notepad++.exe and get me version of this..

i think  something like 

var versionskype = (path  for  program and get version)

var versionnote = (path  for  program and get version)

var chrome = (path  for  program and get version)

label.Text = versionskype + var versionnote  + chrome ;

Hello,

 Using Notepad in my example of C# Console project in VS2012 on Win7; 

Code

using System;
using System.Collections.Generic;
using System.IO;
using System.Text;
using System.Threading.Tasks;

namespace FileVer
{
    class Program
    {
        static void Main( string[] args )
        {
            string src = @"C:\Windows\system32\notepad.exe";

            Console.WriteLine( System.Diagnostics.FileVersionInfo.GetVersionInfo( src ).ToString() );                

        }
    }
}

The below only works for a .NET assembly. If the program is a COM and not a .NET assembly, then it's not going to work.  

string assemblyVersion = Assembly.LoadFile("filepath").GetName().Version.ToString();

You can use Win32 API to get it from a COM assembly, and maybe someone can help you there, because the programs you are talking about might be COM assemblies.

Hi SRhelp,

Agree with User3DX, if you want to get the ProductVersion, you could use the following code.

string chromePath = @"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe";
string chromeVersion = System.Diagnostics.FileVersionInfo.GetVersionInfo(chromePath).ProductVersion;
label.Text = chromeVersion;

All it's going to give is file info, and the assembly version cannot be obtained.

You can try WMI
