 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);

パラメーター

戻り値

Boolean

size1 と size2 の X、Y、Z の各コンポーネントが等しい場合は true。それ以外の場合は false。

例

次の例は、オーバーロードされた等値演算子を使用して、2 つの Size3D 構造体が等しいかどうかを確認する方法を示しています。

// Checks if two Size3D structures are equal using the overloaded == operator. 
// Returns a Boolean.

// Declaring Size3D structure without initializing x,y,z values
Size3D size1 = new Size3D();

// Declaring Size3D structure and initializing x,y,z values
Size3D size2 = new Size3D(5, 10, 15);
Boolean areEqual;

// Assigning values to size1
size1.X = 2;
size1.Y = 4;
size1.Z = 6;

// Checking for equality
areEqual = size1 == size2;

// areEqual is False

// Displaying Results
syntaxString = " areEqual = size1 == size2;";
resultType = "Boolean";
operationString = "Checking if two Size3D structures are equal";
ShowResults(areEqual.ToString(), syntaxString, resultType, operationString);

' Checks if two Size3D structures are equal using the overloaded == operator. 
' Returns a Boolean.

' Declaring Size3D structure without initializing x,y,z values
Dim size1 As New Size3D()

' Declaring Size3D structure and initializing x,y,z values
Dim size2 As New Size3D(5, 10, 15)
Dim areEqual As Boolean

' Assigning values to size1
size1.X = 2
size1.Y = 4
size1.Z = 6

' Checking for equality
areEqual = size1 = size2

' areEqual is False

' Displaying Results
syntaxString = " areEqual = size1 == size2"
resultType = "Boolean"
operationString = "Checking if two Size3D structures are equal"
ShowResults(areEqual.ToString(), syntaxString, resultType, operationString)

注釈

算術演算を実行すると、値の精度が失われる可能性があるため Double 、論理的に等しい 2 つの Size3D インスタンス間の比較が失敗する可能性があります。
