C# checklistbox控件用法总结(怎样得到多选的值，以及动态加载数据)

C# checklistbox控件用法总结(怎样得到多选的值，以及动态加载数据)一般认为：foreach (object obj in checkedListBox1.SelectedItems)即可遍历选中的值。
其实这里遍历的只是高亮的值并不是打勾的值。遍历打勾的值要用下面的代码：
for?<wbr>(<span style="LINE-HEIGHT: 21px; WORD-WRAP: normal; COLOR: rgb(0,0,255); WORD-BREAK: normal">int</span>?<wbr>i?<wbr>=?<wbr><span style="LINE-HEIGHT: 21px; WORD-WRAP: normal; COLOR: rgb(128,0,128); WORD-BREAK: normal">0</span>;?<wbr>i?<wbr>&lt;?<wbr>checkedListBox1.Items.Count;?<wbr>i++)<br>{<br>?<wbr>?<wbr>?<wbr>?<wbr><span style="LINE-HEIGHT: 21px; WORD-WRAP: normal; COLOR: rgb(0,0,255); WORD-BREAK: normal">if</span>?<wbr>(checkedListBox1.GetItemChecked(i))<br>?<wbr>?<wbr>?<wbr>?<wbr>{<br>?<wbr>?<wbr>?<wbr>?<wbr>?<wbr>?<wbr>?<wbr>?<wbr>MessageBox.Show(checkedListBox1.GetItemText(checkedListBox1.Items[i]));<br>?<wbr>?<wbr>?<wbr>?<wbr>}<br>}</wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>参考：
最近用到checklistbox控件，在使用其过程中，花了较多的时间，这里我收集了其相关的代码段，希望对大家有所帮助。
