如何从CheckedListBox获取选中项的值？ [英] How to get value of checked item from CheckedListBox?

问题描述

我在C＃中的WinForm上使用了CheckedListBox。我已将控件的边界如下所示-

I have used a CheckedListBox over my WinForm in C#. I have bounded this control as shown below -

chlCompanies.DataSource = dsCompanies.Tables[0];
chlCompanies.DisplayMember = "CompanyName";
chlCompanies.ValueMember = "ID";

我可以获取已检查项目的索引，但是如何获取已检查项目的文本和值。相反，我该如何枚举CheckedItems访问文本和值？

I can get the indices of checked items, but how can i get checked item text and value. Rather how can i enumerate through CheckedItems accessing Text and Value?

推荐答案

将其恢复为原始类型，如果要绑定表，它将为DataRowView，然后可以从相应的列中获取Id和Text：

Cast it back to its original type, which will be a DataRowView if you're binding a table, and you can then get the Id and Text from the appropriate columns:

foreach(object itemChecked in checkedListBox1.CheckedItems)
{
     DataRowView castedItem = itemChecked as DataRowView;
     string comapnyName = castedItem["CompanyName"];
     int? id = castedItem["ID"];
}
