Matrix.Equals 方法
定義
多載
| Equals(Object) |
判斷所指定 Object 的 Matrix 結構是否與這個 Matrix 相同。Determines whether the specified Object is a Matrix structure that is identical to this Matrix. |
| Equals(Matrix) |
判斷指定的 Matrix 結構是否與這個執行個體相同。Determines whether the specified Matrix structure is identical to this instance. |
| Equals(Matrix, Matrix) |
判斷兩個指定的 Matrix 結構是否相同。Determines whether the two specified Matrix structures are identical. |
範例
下列範例顯示如何檢查兩個 Matrix 結構是否相等。The following example shows how to check two Matrix structures for equality.
private void equalityExample()
{
Matrix matrix1 = new Matrix(5, 10, 15, 20, 25, 30);
Matrix matrix2 = new Matrix(5, 10, 15, 20, 25, 30);
Boolean result;
// result is true.
result = (matrix1 == matrix2);
// result is false.
result = (matrix1 != matrix2);
}
備註
注意
會將 Matrix 其值儲存為雙精度浮點數。A Matrix stores its values as doubles. 因為的值在 Double 執行算數運算時可能會遺失精確度，所以在邏輯上相等的兩個結構之間的比較 Double 可能會失敗。Because the value of a Double can lose precision when arithmetic operations are performed on it, a comparison between two Double structures that are logically equal might fail.

如果 o 的 Matrix 結構與這個 Matrix 結構相同則為 true，否則為 false。true if o is a Matrix structure that is identical to this Matrix structure; otherwise, false.
