小编use*_*418的帖子

我想问一下这是否是检查数字是否为素数的正确方法？因为我读到0和1不是素数.

int num1;

Console.WriteLine("Accept number:");
num1 = Convert.ToInt32(Console.ReadLine());
if (num1 == 0 || num1 == 1)
{
    Console.WriteLine(num1 + " is not prime number");
    Console.ReadLine();
}
else
{
    for (int a = 2; a <= num1 / 2; a++)
    {
        if (num1 % a == 0)
        {
            Console.WriteLine(num1 + " is not prime number");
            return;
        }

    }
    Console.WriteLine(num1 + " is a prime number");
    Console.ReadLine();
}

输出是这样的:

MyNameIsJohnSmithAnd
Imaperson

我想要的是只在一行显示它

MyNameIsJohnSmithAndImaperson

我的Aspx gridview代码是:

<asp:GridView ID="GridView1" runat="server" BackColor="LightGoldenrodYellow" 
    BorderColor="Tan" BorderWidth="1px" CellPadding="5" Font-Names="Calibri" 
    Font-Size="Medium" Font-Underline="False" ForeColor="Black">
    <RowStyle Wrap="False"/>
    <EmptyDataRowStyle Wrap="False"/>
    <FooterStyle BackColor="Tan" BorderColor="Black" BorderStyle="Solid" Wrap="False"/>
    <PagerStyle BackColor="PaleGoldenrod" ForeColor="DarkSlateBlue" 
        HorizontalAlign="Center" Wrap="False" />
    <SelectedRowStyle BackColor="DarkSlateBlue" ForeColor="GhostWhite" Wrap="False"/>
    <HeaderStyle BackColor="Tan" BorderStyle="Solid" Font-Bold="True" Wrap="False"/>
    <EditRowStyle Wrap="False"/>
    <AlternatingRowStyle BackColor="PaleGoldenrod" Wrap="False"/>
</asp:GridView>

我在gridview中禁用了所有的wrap属性为false.但文字仍然包装.

我在SQL中有这个查询

WHERE DATEDIFF(DD,[fld_DateResolved],GETDATE()) > 3

我想要做的是,在我的系统中3天后关闭门票,我的问题是,这是查询以检查DateResolved和GetDate的DATEDIFF是否大于3的正确方法吗？

谢谢

我想展示薪水最高的球员.

select  max(Salary) as highest_salary, p.[Last name]
from tbl_PlayersTable as p, tbl_team as t
where p.Team = t.TeamID
and TeamID = 1000
Group by p.[Last name]

输出是:

highest_salary  Last Name
   8000          Bosh
   7000          Wade
   6000          James

我只想表现出来(因为他是薪水最高的球员,因此他有8000名波什).
