Question

我无法在枢轴页面上显示随机生成的数字。以下是我的代码，

<!--LayoutRoot is the root grid where all page content is placed-->
<ScrollViewer>
    <Grid x:Name="LayoutRoot" Background="Transparent" Height="768" Width="480">
        <!--Pivot Control-->
        <phone:Pivot Title="MY APPLICATION" Loaded="Pivot_Loaded">           

            <!--Pivot item one-->
            <phone:PivotItem Header="Stats">                   
                <Border
                    BorderBrush="{StaticResource PhoneBackgroundBrush}"
                    BorderThickness="{StaticResource PhoneBorderThickness}" Background="Black">
                    <Grid Margin="-3,75,-17,-75">

                        <TextBlock
                            TextWrapping="Wrap"
                            Style="{StaticResource PhoneTextExtraLargeStyle}" Margin="10,121,253,422" FontSize="30" Text="Highest Temp : " />
                        <TextBlock
                            TextWrapping="Wrap"
                            Style="{StaticResource PhoneTextExtraLargeStyle}" Margin="10,0,253,551" Text="Current Temp :" FontSize="30" />
                        <TextBlock
                            TextWrapping="Wrap"
                            Style="{StaticResource PhoneTextExtraLargeStyle}" Margin="10,240,253,311" Text="Lowest Temp : " FontSize="30" />
                        <TextBlock
                            TextWrapping="Wrap"
                            Style="{StaticResource PhoneTextExtraLargeStyle}" Margin="10,360,253,191" Text="Average Temp : " FontSize="30" />
                        <TextBlock Name="TempAverage"
                            TextWrapping="Wrap"
                            Style="{StaticResource PhoneTextExtraLargeStyle}" Margin="222,360,41,191" Text="-" FontSize="30" />
                        <TextBlock Name="TempLowest"
                            TextWrapping="Wrap"
                            Style="{StaticResource PhoneTextExtraLargeStyle}" Margin="222,240,41,311" Text="-" FontSize="30" />
                        <TextBlock Name="TempHighest"
                            TextWrapping="Wrap"
                            Style="{StaticResource PhoneTextExtraLargeStyle}" Margin="222,121,41,430" Text="-" FontSize="30" />
                       <TextBlock Name="TempCurrent"
                            TextWrapping="Wrap"
                            Style="{StaticResource PhoneTextExtraLargeStyle}" Margin="222,0,41,551" Text="-" FontSize="30" />
                    </Grid>
                </Border>

            </phone:PivotItem>

然后它告诉我错误＆＃34;名称＆＃39; TempAverage在当前上下文中不存在＆＃39;。与TempCurrent，TempHighest和TempLowest相同。我面临的错误是什么？我应该怎么做呢？

int a = 0;
void time_Tick(object sender, EventArgs e)
{
    DispatcherTimer time = new DispatcherTimer();
    Random rnd = new Random();
    double TempRandom = rnd.Next(100, 500); //generate random number
    double TempRandom2 = TempRandom / 10;

    ***TempCurrent.Text = TempRandom2.ToString("0.0");

    if(TempRandom2 > Max) 
    {
        Max = TempRandom2; //Highest Temp = Current Temp
        TempHighest.Text = Max.ToString("0.0"); 
    }

    if(TempRandom2 < Min)
    {
        Min = TempRandom2;
        TempLowest.Text = Min.ToString("0.0"); //Lowest Temp = Current Temp
    }

    AvgTemp[a++ % 100] = TempRandom2;
    if (a > 100)
        TempAverage.Text = AvgTemp.Average().ToString("0.0");
    else
        TempAverage.Text = (AvgTemp.Sum() / a).ToString("0.0");***
}

您需要为元素添加名称。例如。 `的TextBlocks。为元素添加名称时，可以在代码中引用它们。像这样。

<TextBlock Name="TempCurrent"
           TextWrapping="Wrap"
           Style="{StaticResource PhoneTextExtraLargeStyle}"
           Margin="10,0,253,551"
           Text="Current Temp :" 
           FontSize="30" />

无法在数据透视c＃WP8上放置多个项目
