例如,foreach以下示例中的 循环显示 数组中的$letterArray值。 PowerShell复制 $letterArray='a','b','c','d'foreach($letterin$letterArray) {Write-Host$letter} 在此示例中,$letterArray包含字符串值a、b、c和d。 语句首次foreach运行时,它将变量设置为$letter
二、foreach也称为只读循环,所以在循环数组/集合的时候,无法对数组/集合进行修改。...foreach循环一般用来数组或集合的迭代,将循环的结果依次赋值给变量,直至遍历完整个数组,如: int[] fibarray = new int[] { 0, 1, 1, 2, 3, 5,...8, 13 }; // foreach遍历数组 foreach (int element in fibar...
