将字典绑定到Combobox [英] Bind a Dictionary to Combobox

问题描述

嗨朋友们......



将字典绑定到COmbobox的最佳方法是什么？

我用过这个...

Hi friends...

Whats the best way to bind a Dictionary to COmbobox?
I have used this...

Dictionary<string,string> ldict = new Dictionary<string,string>();
ldict.Add("English", "En.dll");
ldict.Add("German", "Ge.dll");
ldict.Add("French", "Fr.dll");
comboBox2.DataSource = ldict.ToList();
               comboBox2.ValueMember = "Value";
               comboBox2.DisplayMember = "Key";

combobox2.SelectedValue给出了正确的选定值....但我无法获得选定的密钥...

如果我调用combobox2.SelectedItem它返回整个Dictionary对象....

请建议我该怎么做...



谢谢

combobox2.SelectedValue gives me the correct selected value.... But I cannot get the Selected Key...
If I call combobox2.SelectedItem It returns the whole Dictionary object....
Please suggest me what should I do...

Thanks

推荐答案

我会做以下事情：

I would do the following:

Dictionary<string,string> ldict = new Dictionary<string,string>();
ldict.Add("English", "En.dll");
ldict.Add("German", "Ge.dll");
ldict.Add("French", "Fr.dll");
comboBox2.DataSource = ldict.ToList();
               comboBox2.ValueMember = "Key";
               comboBox2.DisplayMember = "Key";

然后在选择更改中，您可以使用已选择的键从字典中获取值。可能有更好的方法，但我不确定它会是什么。

Then in the select change you can get the value from the dictionary using the key that has been selected. There is probably a better way but I'm not sure what it would be.
