Property Value

Type: System.Boolean

true if the file is prerelease; otherwise, false.

The following example calls GetVersionInfo to get the FileVersionInfo for the Notepad. Then it displays whether this version is a prerelease version in a text box. This code assumes textBox1 has been instantiated.

 private void GetIsPreRelease()
     // Get the file version for the notepad.
     FileVersionInfo myFileVersionInfo =
         FileVersionInfo.GetVersionInfo(Environment.SystemDirectory + "\\Notepad.exe");

     // Print whether the file is a prerelease version.
     textBox1.Text = "File is prerelease version " + myFileVersionInfo.IsPreRelease;
