FrameworkName.Inequality Operator (FrameworkName, FrameworkName)

.NET Framework (current version)
 

Returns a value that indicates whether two FrameworkName objects represent different .NET Framework versions.

Namespace:   System.Runtime.Versioning
Assembly:  System (in System.dll)

public static bool operator !=(
	FrameworkName left,
	FrameworkName right
)

Parameters

left
Type: System.Runtime.Versioning.FrameworkName

The first object to compare.

right
Type: System.Runtime.Versioning.FrameworkName

The second object to compare.

Return Value

Type: System.Boolean

true if the left and right parameters represent different .NET Framework versions; otherwise, false.

The Inequality method defines the operation of the inequality operator for FrameworkName objects.

Languages that do not support custom operators can test for inequality by calling the FrameworkName.Equals(FrameworkName) method and reversing its value.

The following example uses the equality operator to determine whether a FrameworkName object that represents the running version of the .NET Framework is equal to a supported version of the .NET Framework. Note that the two versions are not equal because they do not have identical version numbers.

FrameworkName supportedVer1 = new FrameworkName(".NET Framework, Version=4.0");
FrameworkName actualVersion = new FrameworkName(String.Format(
                                           ".NET Framework, Version={0}", 
                                           Environment.Version.ToString()));

Console.WriteLine("Supported Version: {0}", supportedVer1);
Console.WriteLine("Actual Version:    {0}", actualVersion);
if (supportedVer1 != actualVersion)    
   Console.WriteLine("The supported and actual Framework versions are different.");
else
   Console.WriteLine("The supported and actual Framework versions are the same.");

Console.WriteLine();
// The example displays the following output:
//       The supported and actual Framework versions are different.
