推荐答案

如果你想要做的这一切都在一个视图中，code是这样的：

If you want to do this all in a view, the code would look like this:

@{
Dictionary<string, string> dictionary = new Dictionary<string, string>();
        dictionary.Add("Active", "A");
        dictionary.Add("InActive", "I");
        SelectList list = new SelectList(dictionary, "value", "key");
}
@Html.DropDownList("name", list)

此外，如果你想添加一个空白，它是这样的：

Also if you wanted to add a blank, it would look like this:

@{
Dictionary<string, string> dictionary = new Dictionary<string, string>();
        dictionary.Add("", "");
        dictionary.Add("Active", "A");
        dictionary.Add("InActive", "I");
        SelectList list = new SelectList(dictionary, "value", "key");
}
@Html.DropDownList("name", list)

如果你想有一个特定的项目选择，它是这样的：

And if you wanted to have a particular item selected, it would look like this:

@{
Dictionary<string, string> dictionary = new Dictionary<string, string>();
        dictionary.Add("", "");
        dictionary.Add("Active", "A");
        dictionary.Add("InActive", "I");
        SelectList list = new SelectList(dictionary, "value", "key", "I");
}
@Html.DropDownList("name", list)

请注意，我改变了添加我参数的SelectList 线，这相当于InActice的价值使其在页面加载时进行选择。

Notice I changed the SelectList line adding a "I" parameter, this corresponds to the 'InActice' value causing it to be selected on page load.

这code将在HTML生成这样的：

This code would generate this in HTML:

<select id="name" name="name">
    <option value="A">Active</option>
    <option selected="selected" value="I">InActive</option>
</select>

因此​​，如果这将是静态的，你可以只用这个。您可以删除选择=选择如果需要的话。

我不完全相信你的保存到数据库上面的值的意思，你有一个模型去与这些项目吗？如果您编辑您的问题，并添加你的努力做的，我可以帮你更好的一些例子。

I'm not exactly sure what you mean by "above values saved into database", do you have a model to go with these items? If you edit your question and add some examples of what your trying to do I can help you better.
