For two objects `x` and `y` that have identical runtime types, `Object.ReferenceEquals(x.GetType(),y.GetType())` returns `true`. The following example uses the <xref:System.Object.GetType%2A> method with the <xref:System.Object.ReferenceEquals%2A> method to determine whether one numeric value is the same type as two other numeric values.

> [!NOTE]
> To determine whether an object is a specific type, you can use your language's type comparison keyword or construct. For example, you can use the `TypeOf…Is` construct in Visual Basic or the `is` keyword in C#.

The <xref:System.Object.GetType%2A> method is inherited by all types that derive from <xref:System.Object>. This means that, in addition to using your own language's comparison keyword, you can use the <xref:System.Object.GetType%2A> method to determine the type of a particular object, as the following example shows.

[!code-csharp[System.Object.GetType#2](~/samples/snippets/csharp/VS_Snippets_CLR_System/system.object.gettype/cs/GetTypeEx2.cs#2)]
[!code-csharp-interactive[System.Object.GetType#2](~/samples/snippets/csharp/VS_Snippets_CLR_System/system.object.gettype/cs/GetTypeEx2.cs#2)]
[!code-vb[System.Object.GetType#2](~/samples/snippets/visualbasic/VS_Snippets_CLR_System/system.object.gettype/vb/GetTypeEx2.vb#2)]

The <xref:System.Type> object exposes the metadata associated with the class of the current <xref:System.Object>.



## Examples

[!INCLUDE[interactive-note](~/includes/csharp-interactive-note-some.md)]

The following code example demonstrates that <xref:System.Object.GetType%2A> returns the runtime type of the current instance.
