StringBuilder实现的带数字的排行榜效果实现代码。

要实现上述效果

public static string ShowNewMsg()
{
string Pic1 = “images/yzdp-_15.gif”;
string Pic2 = “images/yzdp-_18.gif”;
string Pic3 = “images/yzdp-_20.gif”;
string Pic4 = “images/yzdp-_22.gif”;
string Pic5 = “images/yzdp-_24.gif”;
string Pic6 = “images/yzdp-_26.gif”;
string Pic7 = “images/yzdp-_28.gif”;
string Pic8 = “images/yzdp-_30.gif”;
string Pic9 = “images/yzdp-_32.gif”;
string Pic10 = “images/yzdp-_34.gif”;
BJMsgInfo Info = new BJMsgInfo();
Info.Version = “cn”;
Info.IsNew = true;
DataTable dt = WebManager.List(Info, “BJUserInfoMsg”, “top 10 UserID,Title,UserTitle,Use

StringBuilder Builder = new StringBuilder();
if (dt.Rows.Count > 0)
{
for (int i = 0; i <dt.Rows.Count; i++)
{
Builder.Append(“

Builder.Append(“if (i == 0)
{
Builder.AppendFormat(“src='{0}'”, Pic1);
}
else if (i == 1)
{
Builder.AppendFormat(“src='{0}'”, Pic2);
}
else if (i == 2)
{
Builder.AppendFormat(“src='{0}'”, Pic3);
}
else if (i == 3)
{
Builder.AppendFormat(“src='{0}'”, Pic4);
}
else if (i == 4)
{
Builder.AppendFormat(“src='{0}'”, Pic5);
}
else if (i == 5)
{
Builder.AppendFormat(“src='{0}'”, Pic6);
}
else if (i == 6)
{
Builder.AppendFormat(“src='{0}'”, Pic7);
}
else if (i == 7)
{
Builder.AppendFormat(“src='{0}'”, Pic8);
}
else if (i == 8)
{
Builder.AppendFormat(“src='{0}'”, Pic9);
}
else if (i == 9)
{
Builder.AppendFormat(“src='{0}'”, Pic10);
}
