问题描述

Good day all, I need some help

I have 10 text boxes to add to get the total sum .. some thing like this

int totalQLoaded = int.Parse(Txt50ClCokeQuantityLoaded.Text) + int.Parse(Txt50ClFantaQuantityLoaded.Text) + int.Parse(Txt50ClSpriteQuantityLoaded.Text)
                + int.Parse(TxtBCokeQuantityLoaded.Text) + int.Parse(TxtBEvaQuantityLoaded.Text) +

//the calculation works fine if all the text boxes are filled with numbers.

but in a situation where some fields are left blank how do i get the total sum ignoring  those field that are blank..

thanks for your time I appreciate

推荐答案

private int GetValue(string s)
    {
    int value = 0;
    if (!string.IsNullOrWhiteSpace(s))
        {
        int.TryParse(s, out value);
        }
    return value;
    }

然后你所要做的就是调用它：

Then all you have to do is call that instead:

int totalQLoaded = GetValue(Txt50ClCokeQuantityLoaded.Text) + 
                   GetValue(Txt50ClFantaQuantityLoaded.Text) +
...
