FrameworkName.Equality(FrameworkName, FrameworkName) Operator

Definition

Namespace:

System.Runtime.Versioning

Assemblies:

netstandard.dll, System.Runtime.dll

Source:

FrameworkName.cs

Returns a value that indicates whether two FrameworkName objects represent the same .NET version.

C#

public static bool operator ==(System.Runtime.Versioning.FrameworkName? left, System.Runtime.Versioning.FrameworkName? right);

Parameters

left

FrameworkName

The first object to compare.

right

FrameworkName

The second object to compare.

Returns

Boolean

true if the left and right parameters represent the same .NET Framework version; otherwise, false.

Examples

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

C#

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 the same.");
else
   Console.WriteLine("The supported and actual Framework versions are different.");

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

Remarks

The Equality method defines the operation of the equality operator for FrameworkName objects.

Languages that do not support custom operators can call the FrameworkName.Equals(FrameworkName) method instead.
