问题描述

if (lbxFecilities.Items.Count > 0)
            {
                for (int i = 0; i < lbxFecilities.Items.Count; i++)
                {
                    if (lbxFecilities.Items[i].Selected)
                    {
                        if (facilities == "")
                            facilities = lbxFecilities.Items[i].Text;
                        else
                            facilities += "," + lbxFecilities.Items[i].Text;
                    }
                }
            }

推荐答案

如果提供了以下NAMESPACE，请点击

1.对于Windows应用程序

Please chk if you have give the following NAMESPACE

1. For Windows Application

using System.Windows.Controls.ListBox

2.对于ASP.Net应用程序

2. For ASP.Net Application

using System.Web.UI.WebControls;

3.对于WPF应用程序

3. For WPF Application

using System.Windows.Documents;

而不是"FOR循环"，请使用以下

And Instead of "FOR Loop" use the following

private void button1_Click(object sender, System.EventArgs e)
 {
     String strItem;
     foreach(Object selecteditem in listBox1.SelectedItems)
     {
         strItem = selecteditem as String;
         MessageBox.Show(strItem);
     }
 }
