示例

以下示例调用 GetVersionInfo 以获取 FileVersionInfo 记事本的 。 然后，它会在文本框中打印文件说明和版本号。 此代码假定 textBox1 已实例化。

#using <System.dll>

using namespace System;
using namespace System::IO;
using namespace System::Diagnostics;


public ref class Class1
{
    
public:
    static void Main()
    {
        // Get the file version for the notepad.
        // Use either of the two following methods.
        FileVersionInfo::GetVersionInfo(Path::Combine(Environment::SystemDirectory, "Notepad.exe"));
        FileVersionInfo^ myFileVersionInfo = FileVersionInfo::GetVersionInfo(Environment::SystemDirectory + "\\Notepad.exe");


        // Print the file name and version number.
        Console::WriteLine("File: " + myFileVersionInfo->FileDescription + "\n" +
           "Version number: " + myFileVersionInfo->FileVersion);
    }
};

int main()
{
    Class1::Main();
}

using System;
using System.IO;
using System.Diagnostics;

class Class1
{
    public static void Main(string[] args)
    {
        // Get the file version for the notepad.
        // Use either of the two following commands.
        FileVersionInfo.GetVersionInfo(Path.Combine(Environment.SystemDirectory, "Notepad.exe"));
        FileVersionInfo myFileVersionInfo = FileVersionInfo.GetVersionInfo(Environment.SystemDirectory + "\\Notepad.exe");

        // Print the file name and version number.
        Console.WriteLine("File: " + myFileVersionInfo.FileDescription + '\n' +
           "Version number: " + myFileVersionInfo.FileVersion);
    }
}

Imports System.IO
Imports System.Diagnostics



Class Class1

    Public Shared Sub Main(ByVal args() As String)
        ' Get the file version for the notepad.
        ' Use either of the following two commands.
        FileVersionInfo.GetVersionInfo(Path.Combine(Environment.SystemDirectory, "Notepad.exe"))
        Dim myFileVersionInfo As FileVersionInfo = FileVersionInfo.GetVersionInfo(Environment.SystemDirectory + "\Notepad.exe")


        ' Print the file name and version number.
        Console.WriteLine("File: " + myFileVersionInfo.FileDescription + vbLf + "Version number: " + myFileVersionInfo.FileVersion)

    End Sub
End Class

注解

通常，版本号显示为“major number.minor number.build number.private part number”。 文件版本号是保存文件的版本号的 64 位数字，如下所示：

• 前 16 位是 FileMajorPart 数字。

• 接下来的 16 位是 FileMinorPart 数字。

• 第三组 16 位是 FileBuildPart 数字。

• 最后 16 位是 FilePrivatePart 数字。
