FileVersionInfo.FileMajorPart Property

.NET Framework 4

Other Versions

Gets the major part of the version number.

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

Syntax

C++

Copy

public int FileMajorPart { get; }

Property Value

Type: System.Int32
A value representing the major part of the version number or 0 (zero) if the file did not contain version information.

Remarks

Typically, a version number is displayed as "major number.minor number.build number.private part number". A file version number is a 64-bit number that holds the version number for a file as follows:

The first 16 bits are the FileMajorPart number.
The next 16 bits are the FileMinorPart number.
The third set of 16 bits are the FileBuildPart number.
The last 16 bits are the FilePrivatePart number.

This property gets the first set of 16 bits.

Examples

The following example calls GetVersionInfo to get the FileVersionInfo for the Notepad. Then it prints the FileMajorPart in a text box. This code assumes textBox1 has been instantiated.

C++

Copy


private void GetFileMajorPart() {
    // Get the file version for the notepad.
    FileVersionInfo myFileVersionInfo = FileVersionInfo.GetVersionInfo("%systemroot%\\Notepad.exe");

    // Print the file major part number.
    textBox1.Text = "File major part number: " + myFileVersionInfo.FileMajorPart;
 }
