# Point3D.Inequality(Point3D, Point3D) Operator

## Definition

Compares two Point3D structures for inequality.

```
public:
static bool operator !=(System::Windows::Media::Media3D::Point3D point1, System::Windows::Media::Media3D::Point3D point2);
```

`public static bool operator != (System.Windows.Media.Media3D.Point3D point1, System.Windows.Media.Media3D.Point3D point2);`

`static member op_Inequality : System.Windows.Media.Media3D.Point3D * System.Windows.Media.Media3D.Point3D -> bool`

`Public Shared Operator != (point1 As Point3D, point2 As Point3D) As Boolean`

#### Parameters

#### Returns

## Examples

The following example shows how to use the overloaded inequality operator to check whether two Point3D structures are not equal.

```
// Checks if two Point3Ds are not equal using the overloaded inequality operator.
Point3D point1 = new Point3D(10, 5, 1);
Point3D point2 = new Point3D(15, 40, 60);
Boolean areNotEqual;
areNotEqual = (point1 != point2);
// areNotEqual is True
// Displaying Results
syntaxString = "areNotEqual = (point1 != point2);";
resultType = "Boolean";
operationString = "Checking if two 3D points are not equal";
ShowResults(areNotEqual.ToString(), syntaxString, resultType, operationString);
```

```
' Checks if two Point3Ds are not equal using the overloaded inequality operator.
Dim point1 As New Point3D(10, 5, 1)
Dim point2 As New Point3D(15, 40, 60)
Dim areNotEqual As Boolean
areNotEqual = (point1 <> point2)
' areNotEqual is True
' Displaying Results
syntaxString = "areNotEqual = (point1 != point2)"
resultType = "Boolean"
operationString = "Checking if two 3D points are not equal"
ShowResults(areNotEqual.ToString(), syntaxString, resultType, operationString)
```

## Remarks

Two Point3D structures are not equal if the values of their X, Y, and Z properties are different.

Because Double values can lose precision when arithmetic operations are performed on them, a comparison between two Point3D instances that are logically equal might fail.
