我不确定，您想要什么确切的输出.但您可以尝试以下解决方案:

I am not sure, what exact output you want. but you can try these solutions:

string Text = ComboBox1.Text;

或者您可以使用

Or you can use

int Index = ComboBox1.SelectedIndex;

sttring text = ComboBox1.Items[Index].ToString;

或

OR

DataRow selectedDataRow = ((DataRowView)comboBox1.SelectedItem).Row;
int Id = Convert.ToInt32(selectedDataRow["Id"]);
string Name = selectedDataRow["Name"].ToString();

int selectedValue = Convert.ToInt32(comboBox1.SelectedValue);
