Definition

Namespace:

System

Assembly:

System.Runtime.dll

Version.cs

Gets the high 16 bits of the revision number.

public:

Public ReadOnly Property MajorRevision As Short

Property Value

Int16

A 16-bit signed integer.

Examples

The following code example demonstrates the Version constructor, and the Major, Minor, Build, Revision, MajorRevision, and MinorRevision properties.

// This example demonstrates the Version.Revision,
// MajorRevision, and MinorRevision properties.

        " major.minor.build.majRev/minRev = {0}.{1}.{2}.{3}/{4}";

    Version^ standardVersion = gcnew Version(2, 4, 1128, 2);
    Version^ interimVersion = gcnew Version(2, 4, 1128, (100 << 16) + 2);

Remarks

Suppose you release an interim version of your application to temporarily correct a problem until you can release a permanent solution. The temporary version does not warrant a new revision number, but it does need to be identified as a different version. In this case, encode the identification information in the high and low 16-bit portions of the 32-bit revision number. Use the Revision property to obtain the entire revision number, use the MajorRevision property to obtain the high 16 bits, and use the MinorRevision property to obtain the low 16 bits.

Starting in the .NET Framework version 2.0, the Windows NT operating system uses the MajorRevision property to encode the service pack number.
