您能告诉我如何在listview中添加列
我有一个名为“_listAvailable”的列表视图，
我需要添加一个名为“Name”的列，但我不知道该怎么做。这是一种简单的方法 ColumnHeader columnHeader1 = new ColumnHeader（）; columnHeader1.Text =“名称”; listView1.Columns.Add（columnHeader1）; 但我们的项目他们做的一切都不同我会给我的编码页面 这里例如“资源策略”是listview中一个列标题的示例（“_ listAvailable”），其名称是“_chPolicy”（编码方使用的变量）。它的文本来自资源文件（.resx）文件

答案 0 :(得分：2)
使用ListView.Columns.Add()
答案 1 :(得分：0)
该行
this._listAvailable = new leaf.Plugins.leafListView();
暗示您的控件来自ListView（事实上，我们无法确定它可能是一个具有类似api的整个其他类）。
这使得每个答案都会被推测出来 - 你的课程可能与ListView不同（例如，它可能会改变一些方法或属性）
答案 2 :(得分：0)
问题很简单实际上一切都来了。它之所以没有在运行时出现的原因我们指的是旧的DLL而不是新的DLL ,,那么它应该怎么来，很抱歉打扰你们
