Vector128.WithElement<T>(Vector128<T>, Int32, T) 方法
定义
重要
一些信息与预发行产品相关，相应产品在发行之前可能会进行重大修改。 对于此处提供的信息，Microsoft 不作任何明示或暗示的担保。
创建一个新的 Vector128<T>，将指定索引处的元素设置为指定值，并将其余元素设置为与给定向量中的值相同的值。

Public Function WithElement(Of T) (vector As Vector128(Of T), index As Integer, value As T) As Vector128(Of T)类型参数
- T
输入向量的类型。
参数
- vector
- Vector128<T>
要从中获取剩余元素的向量。
- index
- Int32
要设置的元素的索引。
- value
- T
要将元素设置到的值。
返回
一个 Vector128<T>，将 index 处的元素值设置为 value，并将其余元素设置为与 vector 中的值相同的值。
例外
不支持 vector 类型 (T)。
index 小于零或者大于元素个数。
