C# ListBox 批量添加数据

Posted 2023-05-18

数组 a[]= 21323,1232332,123332,1233
4个数字
我想用循环的方式把他们赋值给 ListBox 控件，请问要怎么写啊，请大侠们帮忙
C#桌面程序的

在前台增加一个 Listbox控件
和button控件

下面代码，写入button事件
int[] a = 21323, 1232332, 123332, 1233 ;
foreach (int num in a)


this.listBox1.Items.Add(num);
参考技术A int[] a = 1, 2, 3, 4 ;
for (int i = 0; i < a.Length; i++)

listBox1.Items.Add(a[i].ToString());

                        LQ_PublicResourceOutline dmodel = null;
                        dmodel=new LQ_PublicResourceOutline();
                        dmodel.LQ_OutlineId = model.SelectedIds[i];
