如何将所有整数添加到数组

Question

I am trying to add all numbers to an array list, I just have around 14 textboxes and all I want is to add up all the integerts in it. Here is code i am trying

int[] arr1 = new int[] { int.Parse(t1.Text), int.Parse(t2.Text), 
        int.Parse(t3.Text), int.Parse(t4.Text), int.Parse(t5.Text) }; 

Answer 1

Use a foreach loop.

int sum = 0;
foreach(int item in arr1)
{
    sum += item;
}

Answer 2

You can select all the textboxes in your form and then sum them up using LINQ, something like:

int result = Controls.OfType<TextBox>().Sum(x => int.Parse(x.Text));

Note that this will throw an exception if Parse fails.

Answer 3

您可以使用linq：

int sum = arr1.Sum();

Answer 4

只需使用linq：

var arr1 = new[] { t1, t2, t3, t4, t5 }.Select(x => int.Parse(x.Text)).ToArray()

Answer 5

You can use a LINQ expression like this.

int intArr[] = {2, 3, 4, 5};
List<int> intList = intArr.toList();
intList = intList.Sum();
intArr = intList.toArray();
