Property Value

The product version.

Typically, a version number displays as major number.minor number.private part number. You can set it explicitly by setting the assembly version within your assembly manifest. For more information, see Assembly Manifest.

ProductVersion first looks to see if the assembly containing the main executable has the AssemblyInformationalVersion attribute on it. If this attribute exists, it is used for both ProductVersion and CommonAppDataPath. If this attribute does not exist, both properties use the version of the executable file instead.

The following code example gets this property and displays its value in a text box. The example requires that textBox1 has been placed on a form.

private void PrintProductVersion() {
    textBox1.Text = "The product version is: " +

private void PrintProductVersion()
    textBox1.set_Text("The product version is: " 
        + Application.get_ProductVersion());
} //PrintProductVersion
