从 datagridview 单元格 C# 的值更新标签文本

Question

我有一个数据网格视图，我在其中输入时间小时，在其下方是 dataGridview 列每列末尾的页脚标签，用于计算每天的每日总小时数，例如 |星期一|周二|周三

|1 | 2 | 3

|2 | 3 | 4

总共 3 5 6

对于正常输入，它工作正常，但如果我在星期一的第一行（例如）从 1 开始进行任何更改，我将其更改为 5，那么只有该行总数即将到来

在这种情况下，总数将变为 5 2 3

那是下一行在总计算中不考虑

请让我知道我错在哪里。

Answer 1

检查if部分的部分，当不输入时，“montot”清除他的价值，
添加其他：

    if (lblMonTotal.Text.Contains(","))
    {
        strmontot = lblMonTotal.Text.Split(',');
    }
    if (lblMonTotal.Text.Contains("."))
    {
        strmontot = lblMonTotal.Text.Split('.');
    }
    else
    {
        strmontot = new string[2] { montot.ToString(), "0" };
    }


    else if (hr != 0)
    {
        lblMonTotal.Text = hr + ".0" + min;
    }

编辑：他们将“else”更改为“else if”：
