组合框索引 [英] ComboBox Index

问题描述

嗨 我在工作中发现了一个有趣的问题.我在我的Form中为两个ComboBox设置了不同的SelectedIndex值.但是，两个ComboBox的值都与结尾处设置的值相同.
为什么会这样呢?
我的代码是这样的:

Hi I found an interesting issue during my work. I am setting different SelectedIndex values to two ComboBoxes in my Form. But both the ComboBoxes have the same value which is set at the end.
Why this might be so?
My code is like this:

var list = new List<system.collections.dictionaryentry>();
list.Add(new System.Collections.DictionaryEntry("one", 1));
list.Add(new System.Collections.DictionaryEntry("two", 2));

comboBox1.DataSource = list;
comboBox1.DisplayMember = "Key";
comboBox1.ValueMember = "Value";
comboBox1.SelectedIndex = 0;

comboBox2.DataSource = list;
comboBox2.DisplayMember = "Key";
comboBox2.ValueMember = "Value";
comboBox2.SelectedIndex = 1;

在此函数的结尾，comboBox1和comboBox2的SelectedIndex值都为1，而不是分别为0和1.
任何的想法? :)
问候

Here at the end of the function, both comboBox1 and comboBox2 have SelectedIndex value as 1 instead of being 0 and 1 respectively.
Any idea? :)
