# Vector3D.LengthSquared Property

## Definition

Gets the square of the length of this Vector3D structure.

```
public:
property double LengthSquared { double get(); };
```

`public double LengthSquared { get; }`

`member this.LengthSquared : double`

`Public ReadOnly Property LengthSquared As Double`

#### Property Value

## Examples

The following example shows how to get the square of the length of a Vector3D structure.

```
// Gets the square of the length of a Vector3D.
// Returns a Vector3D.
Vector3D vector1 = new Vector3D(20, 30, 40);
Double lengthSq;
lengthSq = vector1.LengthSquared;
// lengthSq is equal to 2900
```

```
' Gets the square of the length of a Vector3D.
' Returns a Vector3D.
Dim vector1 As New Vector3D(20, 30, 40)
Dim lengthSq As Double
lengthSq = vector1.LengthSquared
' lengthSq is equal to 2900
```

## Remarks

The length of a Vector3D is sometimes referred to as the magnitude.
