C# 에 ComboBox에 첫번째 항목으로 선택하게 하는 코드 You can set using SelectedIndex comboBox1.SelectedIndex= 1; OR SelectedItem comboBox1.SelectedItem = "your value"; // The latter won't throw an exception if the value is not available in the comobo box EDIT If the value to be selected is not specific then you would be better off with this comboBox1.SelectedIndex = comboBox1.Items.Count - 1; or comboBox1.Selecte..
