我有一個數據表,其中有一個「總計」列。我希望能夠獲得特定的行「Total」而不是所有的行。使用DataTable的特定行
public void maxValue()
{
string pass = (String)Session["name"];
DataTable table = (DataTable)Session["CocaCola"];
int total = table.AsEnumerable().Sum(r => r.Field<int>("Total"));
int totalAllowed = table.AsEnumerable().Sum(r => r.Field<Int32>("Total Allowed"));
if (total >= totalAllowed)
{
Label1.Text = "Total value exceeded the maximum of " + totalAllowed;
}
else if (total < totalAllowed)
{
Label1.Text = "Total value which is allowed :" + totalAllowed;
}
if (pass.Equals("Low"))
{
Label1.Text = "You are not allowed any assets at this Stage";
//SNS.Checked = false;
//TT.Checked = false;
//Music.Checked = false;
//SNS.Enabled = false;
//TT.Enabled = false;
//Music.Enabled = false;
}
}
正如你可以看到我的方法工作,但添加我不想做的列。我將如何去改變它?
