sqlserver中的数据
在gridview中调用它
如何在列中添加所有时间,我有4列来计算不同的总时间
例如:
时间1 = 256.20(HH.mm)
时间2 = 257.41(HH.mm)
时间3 = 114.50(HH.mm)
时间4 = 371.20(HH.mm)
总计= 1000.11(HH.mm)
总数将继续增加,但格式必须是小时和分钟 我使用字符串拆分在上面添加了2次时间1 在C#.net
中完成提前感谢你。
非常感谢@CodingYoshi

// totalHours = totalHours + 1;
// totalMinutes = totalMinutes % 60;
//}
var times = new List<string>
{
TextBox1.Text,TextBox2.Text
};
TimeSpan total = new TimeSpan();
foreach (var thisString in times)
{
var split = thisString.Split('.');
total = total.Add(new TimeSpan(int.Parse(split[0]), int.Parse(split[1]), 0));
}
var totalHours = (int)total.TotalHours;
var totalMinutes = total.Minutes;
TextBox3.Text = totalHours.ToString() + "." + totalMinutes.ToString();
来自gridview的
SqlCommand cmd = con.CreateCommand();
cmd.CommandText = "select * from totalHours";
SqlDataReader dr = cmd.ExecuteReader();
DataTable dt = new DataTable();
dt.Load(dr);
GridView1.DataSource = dt;
GridView1.DataBind();
TimeSpan total = new TimeSpan();
var times = new List<string> ();
for (int i = 0; i < GridView1.Rows.Count; i++)
{
times.Add((GridView1.Rows[i].Cells[0].Text));
}
foreach (var thisString in times)
{
var split = thisString.Split('.');
total = total.Add(new TimeSpan(int.Parse(split[0]), int.Parse(split[1]), 0));
}
var totalHours = (int)total.TotalHours;
var totalMins = total.Minutes;
Label2.Text = totalHours.ToString() + "." + totalMins.ToString();
再次感谢@CodingYoshi
答案 0 :(得分:2)
我在这里添加其中的两个,你可以完成其余的工作:
<input class="text" type="text" name="name" value="<?= $username ?>" />
@posts = Post.limit(params[:limit])
会显示添加var t1 = new TimeSpan(256, 20, 0);
var t2 = new TimeSpan(257, 41, 0);
var tTotal = t1.Add(t2).ToString(@"dd\.hh\:mm\:ss");
和tTotal
的日期,时间,分钟和秒数;
如果你想使用循环来完成它们,你可以这样做:
t1
如果您想要总小时数和分钟数:
t2
