FileVersionInfo.IsSpecialBuild Property

Gets a value that specifies whether the file is a special build.

Namespace:  System.Diagnostics
Assembly:  System (in System.dll)

public bool IsSpecialBuild { get; }

Property Value

Type: System.Boolean
true if the file is a special build; otherwise, false.

A file that is a special build was built using standard release procedures, but the file differs from a standard file of the same version number. If this value is true, the SpecialBuild property must specify how this file differs from the standard version.

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

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

    // Print whether the file is a special build.
    textBox1.Text = "File is a special build: " + myFileVersionInfo.IsSpecialBuild;
