我怎樣才能使它在組合框控件中只顯示每個項目名稱的一部分？

Question

這是我如何列出並將所有win32項目添加到組合框。

using System; 
using System.Collections; 
using System.Management; 
using System.Collections.Generic; 
using System.ComponentModel; 
using System.Data; 
using System.Drawing; 
using System.Text; 
using System.Windows.Forms; 

namespace GetHardwareInfo 
{ 
    public partial class frmMain : Form 
    { 
     public frmMain() 
     { 
      InitializeComponent(); 

      cmbxOption.SelectedItem = "Win32_Processor"; 
      cmbxStorage.SelectedItem = "Win32_DiskDrive"; 
      cmbxMemory.SelectedItem = "Win32_CacheMemory"; 
      cmbxSystemInfo.SelectedItem = ""; 
      cmbxNetwork.SelectedItem = "Win32_NetworkAdapter"; 
      cmbxUserAccount.SelectedItem = "Win32_SystemUsers"; 
      cmbxDeveloper.SelectedItem = "Win32_COMApplication"; 
      cmbxUtility.SelectedItem = "Win32_1394Controller"; 


     } 

     private void InsertInfo(string Key, ref ListView lst, bool DontInsertNull) 
     { 
      lst.Items.Clear(); 

      ManagementObjectSearcher searcher = new ManagementObjectSearcher("select * from " + Key); 

      try 
      { 
       foreach (ManagementObject share in searcher.Get()) 
       { 

        ListViewGroup grp; 
        try 
        { 
         grp = lst.Groups.Add(share["Name"].ToString(), share["Name"].ToString()); 
        } 
        catch 
        { 
         grp = lst.Groups.Add(share.ToString(), share.ToString()); 
        } 

        if (share.Properties.Count <= 0) 
        { 
         MessageBox.Show("No Information Available", "No Info", MessageBoxButtons.OK, MessageBoxIcon.Information); 
         return; 
        } 

        foreach (PropertyData PC in share.Properties) 
        { 

         ListViewItem item = new ListViewItem(grp); 
         if (lst.Items.Count % 2 != 0) 
          item.BackColor = Color.White; 
         else 
          item.BackColor = Color.WhiteSmoke; 

         item.Text = PC.Name; 

         if (PC.Value != null && PC.Value.ToString() != "") 
         { 
          switch (PC.Value.GetType().ToString()) 
          { 
           case "System.String[]": 
            string[] str = (string[])PC.Value; 

            string str2 = ""; 
            foreach (string st in str) 
             str2 += st + " "; 

            item.SubItems.Add(str2); 

            break; 
           case "System.UInt16[]": 
            ushort[] shortData = (ushort[])PC.Value; 


            string tstr2 = ""; 
            foreach (ushort st in shortData) 
             tstr2 += st.ToString() + " "; 

            item.SubItems.Add(tstr2); 

            break; 

           default: 
            item.SubItems.Add(PC.Value.ToString()); 
            break; 
          } 
         } 
         else 
         { 
          if (!DontInsertNull) 
           item.SubItems.Add("No Information available"); 
          else 
           continue; 
         } 
         lst.Items.Add(item); 
        } 
       } 
      } 


      catch (Exception exp) 
      { 
       MessageBox.Show("can't get data because of the followeing error \n" + exp.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Information); 
      } 


     } 

     private void RemoveNullValue(ref ListView lst) 
     { 
      foreach (ListViewItem item in lst.Items) 
       if (item.SubItems[1].Text == "No Information available") 
        item.Remove(); 
     } 


     #region Control events ... 

     private void cmbxNetwork_SelectedIndexChanged(object sender, EventArgs e) 
     { 
      InsertInfo(cmbxNetwork.SelectedItem.ToString(), ref lstNetwork, chkNetwork.Checked); 
     } 

     private void linkLabel1_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e) 
     { 
      linkLabel1.LinkVisited = true; 
     } 

     #endregion 


    } 
} 

我所得到的是，在這種情況下的組合框我把它稱爲最終cmbxNetwork我在它的許多項目都開始以Win32_ 例如當我點擊組合框，我看到的第一個項目是看： 「Win32_NetworkAdapter」

相反Win32_NetworkAdapter我想只有組合框看到：NetworkAdapter 但是，當我選擇它應該被選爲Win32_NetworkAdapter的項目，但用戶應該看到並僅選擇NetworkAdapter。

我想刪除從Win32_ 但只有用戶將看到它沒有Win32_

而且在構造函數中，當我現在在做組合框項目的測試：cmbxNetwork.SelectedItem =「Win32_NetworkAdapter」;所以相反，如果我在做：cmbxNetwork.SelectedItem =「NetworkAdapter」;這將是足夠的。該程序將使用「Win32_NetworkAdapter」;但同樣我看到的用戶在ComboBox的產品只有NetworkAdapter

你可能會從密封值和顯示字符串的自寫的結構，使用對象：

class Box { 
    public object Value { get; set; } 
    public string Display { get; set; } 

    public override string ToString() { return Display; } 
} 

把你的值到一個Box -class並定義一個顯示字符串。 ComboBox將顯示ToString的結果。
