c# - 将一个 int 添加到它的现有数组中

Question

这是我试过的代码

int[] WeeklyTotal = new int[53];
for (int w = 1; w <= 53; w++)
{
    WeeklyTotal[w] = WeeklyTotal[w] + data.Rows[i]["week" + w];  // Error is here
}

但是我遇到了一个编译错误:

Can not apply opperator + to opperands of type int and object

这里正确的语法是什么？

谢谢!

Answer 1

您需要将 object 类型转换为 integer 类型

WeeklyTotal[w] = WeeklyTotal[w] + (int)data.Rows[i]["week" + w]; 

还需要更新循环逻辑的数组迭代，否则索引将超出范围，并且会抛出 IndexOutOfRangeException

for (int w = 0; w < WeeklyTotal.Length; w++)
{
    WeeklyTotal[w] = WeeklyTotal[w] + (int)data.Rows[i]["week" + w];
}
