一些信息与预发行产品相关，相应产品在发行之前可能会进行重大修改。 对于此处提供的信息，Microsoft 不作任何明示或暗示的担保。
获取一个值，该值指定该文件是否为开发版本，而不是用于商业目的的发行版。
public:
property bool IsPreRelease { bool get(); };C#
public bool IsPreRelease { get; }member this.IsPreRelease : boolPublic ReadOnly Property IsPreRelease As Boolean如果该文件是预发行版本，则为 true；否则为 false。
以下示例调用 GetVersionInfo 以获取 FileVersionInfo 记事本的 。 然后在文本框中显示此版本是否为预发行版本。 此代码假定 textBox1 已实例化。
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 = String::Concat( "File is prerelease version ", myFileVersionInfo->IsPreRelease );
}
C#
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;
}
Private Sub GetIsPreRelease()
' Get the file version for the notepad.
Dim myFileVersionInfo As FileVersionInfo = _
FileVersionInfo.GetVersionInfo(Environment.SystemDirectory + "\Notepad.exe")
' Print whether the file is a prerelease version.
textBox1.Text = "File is prerelease version " & myFileVersionInfo.IsPreRelease
End Sub
