大家好，

我有一个带有Silverlight中静态数据的ComboBox.我的代码如下:

Hello all,

I have a ComboBox with static data in silverlight. My code is as follows:

<ComboBox Grid.Column="1" Grid.Row="4" Height="23" HorizontalAlignment="Left" Name="comboBox1" VerticalAlignment="Top" Width="120">
           <ComboBox.Items>
           <ComboBoxItem  Content="ASX_D"></ComboBoxItem>
           <ComboBoxItem Content="FOREX_D"></ComboBoxItem>
           <ComboBoxItem Content="FOREX_H"></ComboBoxItem>
           <ComboBoxItem Content="FUTERE_H"></ComboBoxItem>
           <ComboBoxItem Content="FUTURE_D"></ComboBoxItem>
           <ComboBoxItem Content="TRADE_H"></ComboBoxItem>
           </ComboBox.Items>
       </ComboBox>

我想在单击按钮时从组合框中选择selecteditem.
我正在使用:

I want to pick the selecteditem from combobox on a button click.
i am using:

string st=comboBox1.SelectedItem.ToString();

但它返回System.Windows.Controls.ComboBoxItem
请向我建议如何选择组合框的选定项目.

非常感谢您的帮助.

推荐答案

也许您需要:

Perhaps you need:

string st = ((ComboBoxItem)comboBox1.SelectedItem).Content.ToString();

var itemType = MyCombBox.SelectedItem.GetType();
var pi = itemType.GetProperty(MyCombBox.DisplayMemberPath);
var stringValue = pi.GetValue(MyCombBox.SelectedItem, null).ToString();
