Data binding data to Repeater 数据绑定数据中继器

hello all,I am using A Repeater inside it i have label. I am fill the text of label as
你们好,我使用一个里面有标签的Repeater。我填写标签的文本是
protected void rptFoprcast_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemIndex > -1)
{
Label lblTargetPrice = new Label();
lblTargetPrice=(Label)e.Item.FindControl("lblTargetpric");
lblTargetPrice.Text=FillTargetPrice(str1).ToString();
}
}

protected double FillTargetPrice(string str)
{

double n = 0.0;
conn = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["ConnString"].ConnectionString);
cmd = new SqlCommand(str, conn);
SqlDataAdapter da = new SqlDataAdapter(cmd);
try
{
conn.Open();
SqlDataReader dr = cmd.ExecuteReader();
while (dr.Read())
{
n = Convert.ToDouble(dr.GetValue(0));
}
conn.Close();
return n;
}
catch (Exception ex)
{
string msg;
msg = ex.Message;
return n;
}
}

But it is biding the targetPrice find last time to the label time how many time finds. Means suppose result found are 50,30,80 and 120 then label apears 4 times and every times 120 dispays.please help me display label with 4 values.但它是等候targetPrice找到上次的标签多少时间发现。意味着假设结果发现50岁,30岁,80年和120年然后标签天际4次,每一次120幅。请帮我用4值显示标签。

I think all Labels has a same name (lblTargetPrice).That makes all of label shows 120 when you run it.....
我认为所有的标签都有一个相同的名字（lblTargetPrice），当你运行它时，使所有标签显示120，
