我的WPF组合框仅包含文本条目.用户将选择一个. 获取所选ComboBoxItem文本的最简单方法是什么?请同时使用C#和Visual Basic进行回答.这是我的组合框:

My WPF ComboBox contains only text entries. The user will select one. What is the simplest way to get the text of the selected ComboBoxItem? Please answer in both C# and Visual Basic. Here is my ComboBox:

<ComboBox Name="cboPickOne">
    <ComboBoxItem>This</ComboBoxItem>
    <ComboBoxItem>should be</ComboBoxItem>
    <ComboBoxItem>easier!</ComboBoxItem>
</ComboBox>

顺便说一句，我知道答案，但要找到它并不容易.我以为我会发布问题来帮助他人.修订:我学会了一个更好的答案.通过将SelectedValuePath ="Content"添加为ComboBox属性，我不再需要难看的转换代码.请参阅下面的安迪的答案.

By the way, I know the answer but it wasn't easy to find. I thought I'd post the question to help others. REVISION: I've learned a better answer. By adding SelectedValuePath="Content" as a ComboBox attribute I no longer need the ugly casting code. See Andy's answer below.

推荐答案

<ComboBox 
  Name="cboPickOne"
  SelectedValuePath="Content"
  >
  <ComboBoxItem>This</ComboBoxItem>
  <ComboBoxItem>should be</ComboBoxItem>
  <ComboBoxItem>easier!</ComboBoxItem>
</ComboBox>

在代码中:

   stringValue = cboPickOne.SelectedValue.ToString()
