wpfcomboBox取值问题

这是获取值后台代码

PRivate void button1_Click(object sender, RoutedEventArgs e)

{

combBox = this.comboBox1.SelectedItem as ComboBoxItem;

combBox1 = this.comboBox2.SelectedItem as ComboBoxItem;

string type = combBox.Content.ToString();

string type1 = combBox1.Content.ToString();

MessageBox.Show(type+type1);

}

ComboBoxItem combBox;

ComboBoxItem combBox1;

string value = "";

private void comboBox1_SelectionChanged(object sender, SelectionChangedEventArgs e)

{

ComboBoxItem cbItem = (ComboBoxItem)(sender as ComboBox).SelectedItem;

value = cbItem.Content.ToString();

MessageBox.Show(value);

// string v = (sender as ComboBox).SelectedValue.ToString();

// string bx= v as string;

// MessageBox.Show(bx);

}
