问题描述
我知道如果我们想在for循环中每次将索引i增加到1,我们写i ++
但是我想每次将i增加到7。我已经给了我的代码。请有人帮帮我!!!
if (ddlMaintenPlan .SelectedItem.Text == 每周)
{
DateTime dtLastday = Convert.ToDateTime(dtpMaintenceEnd.Text.Trim());
while (dsStartDate < = dtLastday)
{
for ( int i = Convert.ToInt32(dsStartDate); i < Convert.ToInt32(dtLastday); i ++)
{
dsStartDate = Convert.ToDateTime(Convert.ToInt32(dsStartDate)+ Convert.ToInt32(i.ToString() ));
DRLocal = DTLocal.NewRow();
DTLocal.Rows.Add(dsStartDate);
}
}
}
解决方案
for ( int i = Convert.ToInt32(dsStartDate); i < Convert.ToInt32(dtLastday); i + = 7 )
I know that if we want to increase the index i into 1 every time in a for loop we write i++
But I want to increase i into 7 every time. I have given my code. Can anyone help me, please!!!
if (ddlMaintenPlan.SelectedItem.Text == "Weekly")
{
DateTime dtLastday = Convert.ToDateTime(dtpMaintenceEnd.Text.Trim());
while (dsStartDate <= dtLastday)
{
for (int i = Convert.ToInt32(dsStartDate); i < Convert.ToInt32(dtLastday); i++)
{
dsStartDate = Convert.ToDateTime(Convert.ToInt32(dsStartDate) + Convert.ToInt32(i.ToString()));
DRLocal = DTLocal.NewRow();
DTLocal.Rows.Add(dsStartDate);
}
}
}
解决方案
for (int i = Convert.ToInt32(dsStartDate); i < Convert.ToInt32(dtLastday); i += 7)
