Getting the Version of my C# app?

Question

I am working on desktop application. I have create a setup.

Ex. My Application. Version is 1.0.0.

I want to get the current version of my desktop application which is 1.0.0. I have tried by using Application.ProductVersion but it provides the version of my controls. (I am using DevExpress Control15.2.7, so it provides the current version as 15.2.7).

How can I get the current version of the installed application? I want to compare it to the installed version to provide a "New Version Available" functionality for my product.

Answer 1

The info you are looking for is in AssemblyInfo.cs.

To access the info written in there at runtime you can use the System.Reflection.Assembly.

Use System.Reflection.Assembly.GetExecutingAssembly() to get the assembly (that this line of code is in) or use System.Reflection.Assembly.GetEntryAssembly() to get the assembly your project started with (most likely this is your app).

In multi-project solutions this is something to keep in mind!

string version = Assembly.GetExecutingAssembly().GetName().Version.ToString() // returns 1.0.0.0 

Corresponding AssemblyInfo.cs:

Corresponding EXE-properties:

This may be important when working with InstallShield (see comments) !

Answer 2

System.Reflection.Assembly executingAssembly = System.Reflection.Assembly.GetExecutingAssembly(); var fieVersionInfo = FileVersionInfo.GetVersionInfo(executingAssembly .Location); var version = fieVersionInfo.FileVersion;
