获取我的 C# 应用程序的版本？

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 Control 15.2.7, 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;

Answer 3

Get the version of a specific assembly:

private const string AssemblyName = "MyAssembly"; // Name of your assembly

public Version GetVersion()
{
    // Get all the assemblies currently loaded in the application domain.
    Assembly[] assemblies = Thread.GetDomain().GetAssemblies();

    for (int i = 0; i < assemblies.Length; i++)
    {
        if (string.Compare(assemblies[i].GetName().Name, AssemblyName) == 0)
        {
            return assemblies[i].GetName().Version;
        }
    }

    return Assembly.GetExecutingAssembly().GetName().Version; // return current version assembly or return null;
}

Answer 4

Another approach, which is basically the same as the accepted answer, is:

Version appVersion = Assembly.GetExecutingAssembly().GetName().Version;
versionLabel.Text = "v" + appVersion.Major + "." + appVersion.Minor + "." + appVersion.Build + ".";
