Get combobox set value as string
提问by Marek Buchtela
Found several ways to do so, but none of them works for me.. I have a combobox with variable number of options (taken from dynamic xml file). For next, I need to know what the user choosed, and I cant find out how to do it. This is one of ways I found and tried:
找到了几种方法，但它们都不适合我。我有一个带有可变数量选项的组合框（取自动态 xml 文件）。接下来，我需要知道用户选择了什么，但我不知道如何去做。这是我发现并尝试过的方法之一：
string myString = myCombobox.SelectedValue.ToString();
At least I dont get an error, but when I try to show that string, it does nothing.
至少我没有收到错误消息，但是当我尝试显示该字符串时，它什么也没做。

Try with myCombobox.SelectedValue.Value.ToString()or myCombobox.SelectedValue.Text.ToString(). Anyway, this question is too low quality for this forum. You need to do some research before asking. That's why I'm voting down you.
尝试使用myCombobox.SelectedValue.Value.ToString()或myCombobox.SelectedValue.Text.ToString()。无论如何，这个问题对于这个论坛来说质量太低了。在问之前你需要做一些研究。这就是我投票否决你的原因。

try myCombobox.SelectedItem.ToString();
试试 myCombobox.SelectedItem.ToString();
it will work if you are adding items to the combobox using this way:
如果您使用这种方式将项目添加到组合框，它将起作用：
comboBox1.Items.Add("Item");
e.g.
例如
myComboBox.Items.Add("Item1");
myComboBox.Items.Add("Item2");
myComboBox.Items.Add("Item3");
myComboBox.SelectedIndex = 1; //force change selection
Console.WriteLine(myComboBox.SelectedItem.ToString()); //will output Item2

Use mycombobox.SelectedItem.ToString();Instead of the SelectedValue
使用mycombobox.SelectedItem.ToString();代替SelectedValue
