示例

下面的代码示例创建一个ListView控件, 其中ListViewItem指定了三个ListViewItem.ListViewSubItem对象, 并为每个项指定了三个对象。The following code example creates a ListView control with three ListViewItem objects specified and three ListViewItem.ListViewSubItem objects specified for each item. 该示例还创建ColumnHeader了用于在详细信息视图中显示子项的对象。The example also creates ColumnHeader objects to display the subitems in details view. ImageList代码示例中还创建了两个对象, 以便为ListViewItem对象提供图像。Two ImageList objects are also created in the code example to provide images for the ListViewItem objects. 这些ImageList对象将添加LargeImageList到和SmallImageList属性。These ImageList objects are added to the LargeImageList and SmallImageList properties. 该示例使用以下属性创建ListView控件:The example uses the following properties in creating the ListView control:

此示例要求您已将代码添加到Form , 并从构造函数或窗体上的其他方法调用在此示例中创建的方法。This example requires that you have added the code to a Form and call the method created in the example from the constructor or another method on the form. 该示例还要求MySmallImage1名为MyLargeImage1MySmallImage2、和MyLargeImage2的映像位于驱动器 C 的根目录中。The example also requires that images named MySmallImage1, MySmallImage2, MyLargeImage1, and MyLargeImage2 are located in the root directory of drive C.
