Basically, it depends on how you fill your ListView.
基本上，这取决于您如何填写ListView.
Anyway, a code like this, should work in almost every situations:
无论如何，像这样的代码应该适用于几乎所有情况：
var idIdx = listView1.Columns["ID"].Index;
var codeIdx = listView1.Columns["Code"].Index;
foreach (ListViewItem item in listView1.Items)
{
if (item.SubItems[idIdx].Text == "2")
{
item.SubItems[codeIdx].Text = "new value...";
break;
}
}
Just a caveat:
只是一个警告：
to assure the first 2 lines of this code work, you must properly initialize your columns' Nameproperty, when you create them:
为确保此代码的前 2 行有效，您必须Name在创建列时正确初始化它们的属性：
either by using the proper add overload:
通过使用正确的添加重载：
listView1.Columns.Add("ID", "ID");
or by setting it later:
或稍后设置：
var col = listView1.Columns.Add("ID");
col.Name = "ID";
