Operator

## Definition

```
public:
static bool operator !=(System::Windows::Media::Media3D::Size3D size1, System::Windows::Media::Media3D::Size3D size2);
```

`public static bool operator != (System.Windows.Media.Media3D.Size3D size1, System.Windows.Media.Media3D.Size3D size2);`

`static member op_Inequality : System.Windows.Media.Media3D.Size3D * System.Windows.Media.Media3D.Size3D -> bool`

`Public Shared Operator != (size1 As Size3D, size2 As Size3D) As Boolean`

#### Parameters

#### Returns

## Examples

The following example shows how to use the overloaded inequality operator to check if two Size3D structures are not equal.

```
// Checks if two Size3D structures are not equal using the overloaded != operator.
// Returns a Boolean.
Size3D size1 = new Size3D(2, 4, 6);
Size3D size2 = new Size3D(5, 10, 15);
Boolean areNotEqual;
areNotEqual = size1 != size2;
// areNotEqual is True
// Displaying Results
syntaxString = "areNotEqual = size1 != size2;";
resultType = "Boolean";
operationString = "Checking if two Size3D structures are not equal";
ShowResults(areNotEqual.ToString(), syntaxString, resultType, operationString);
```

```
' Checks if two Size3D structures are not equal using the overloaded != operator.
' Returns a Boolean.
Dim size1 As New Size3D(2, 4, 6)
Dim size2 As New Size3D(5, 10, 15)
Dim areNotEqual As Boolean
areNotEqual = size1 <> size2
' areNotEqual is True
' Displaying Results
syntaxString = "areNotEqual = size1 != size2"
resultType = "Boolean"
operationString = "Checking if two Size3D structures are not equal"
ShowResults(areNotEqual.ToString(), syntaxString, resultType, operationString)
```

## Remarks

Because Double values can lose precision when arithmetic operations are performed on them, a comparison between two Size3D instances that are logically equal might fail.
