如何通過輸入其編號來選擇不同的清單項目項目

我想通過在文本框中輸入唯一的編號來選擇不同的清單項目項目。這些項目包含員工姓名及其編號。我的代碼如下：如何通過輸入其編號來選擇不同的清單項目項目

private void txtEmpID_TextChanged(object sender, EventArgs e) 
    { 
     SelectEmployeeList(txtEmpID.Text); 
    } 


    public string ParseName(string Name) 
    { 
     Regex regexObj = new Regex(@"[^\d]"); 
     string EMP_ID = regexObj.Replace(Name, ""); 
     return EMP_ID; 
    } 


    public void SelectEmployeeList(string str) 
    { 
     for (int i = 0; i < chkListBoxLoadName.Items.Count; i++) 
     { 
      string Name = ParseName(chkListBoxLoadName.Items[i].ToString()); 
      if (str == Name) 
      { 
       chkListBoxLoadName.SetItemChecked(i,true); 
      } 
      else 
      { 
       chkListBoxLoadName.SetItemChecked(i,false); 
      } 
     } 
    }

不錯的代碼，現在它出錯了嗎？我做「有點」瞭解你的問題，但我沒有看到你的代碼中的問題。我的意思是代碼可以在這裏和那裏使用一些改進。但請更詳細地描述問題，也許指向代碼中的行。 – Bazzz 2011-04-19 06:47:11

你不需要使用這個正則表達式。簡單的解決方法是使用LINQ和字符串數組像這樣（在我的事件處理程序例如爲框TextChanged）：

string[] blocks = ((TextBox)sender).Text.Split(' '); 
    for (int idx = 0; idx < clb_CheckedListBox.Items.Count; idx++) 
    clb_CheckedListBox.SetItemChecked(idx, clb_CheckedListBox.Items[idx].ToString().Split(' ').Intersect(blocks).Any());

你可以用這個下一個代碼運行完全的例子（我不能上傳圖片，所以我完全貼在這裏運行main .cs文件的內容）：

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Threading.Tasks; 
using System.Windows.Forms; 

namespace Test 
{ 
    static class Program 
    { 
     [STAThread] 
     static void Main() 
     { 
      Application.EnableVisualStyles(); 
      Application.SetCompatibleTextRenderingDefault(false); 
      Application.Run(new Example()); 
     } 
    } 

    public partial class Example : Form 
    { 
     private System.Windows.Forms.CheckedListBox clb_CheckedListBox; 
     private System.Windows.Forms.TextBox txb_TextBox; 

     public Example() 
     { 
      this.clb_CheckedListBox = new System.Windows.Forms.CheckedListBox(); 
      this.txb_TextBox = new System.Windows.Forms.TextBox(); 
      this.SuspendLayout(); 
      this.clb_CheckedListBox.FormattingEnabled = true; 
      this.clb_CheckedListBox.Items.AddRange(new object[] { 
      "John 1455", "Jenny 786", "Bob 410", "Adam 97", "Jennifer 4100"}); 
      this.clb_CheckedListBox.Location = new System.Drawing.Point(13, 13); 
      this.clb_CheckedListBox.Name = "clb_CheckedListBox"; 
      this.clb_CheckedListBox.Size = new System.Drawing.Size(168, 139); 
      this.txb_TextBox.Location = new System.Drawing.Point(187, 13); 
      this.txb_TextBox.Multiline = true; 
      this.txb_TextBox.Name = "txb_TextBox"; 
      this.txb_TextBox.Size = new System.Drawing.Size(205, 139); 
      this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F); 
      this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font; 
      this.ClientSize = new System.Drawing.Size(404, 166); 
      this.Controls.Add(this.txb_TextBox); 
      this.Controls.Add(this.clb_CheckedListBox); 
      this.ResumeLayout(false); 
      this.PerformLayout(); 

      this.txb_TextBox.TextChanged += new System.EventHandler(this.txb_TextBox_TextChanged); 
      this.Load += new System.EventHandler(this.TestForm_Load); 
     } 

     private void txb_TextBox_TextChanged(object sender, EventArgs e) 
     { 

      string[] blocks = ((TextBox)sender).Text.Split(' '); 
      for (int idx = 0; idx < clb_CheckedListBox.Items.Count; idx++) 
       clb_CheckedListBox.SetItemChecked(idx, clb_CheckedListBox.Items[idx].ToString().Split(' ').Intersect(blocks).Any()); 
     } 

     private void TestForm_Load(object sender, EventArgs e) 
     { 
      this.txb_TextBox.Text = "John 410 Jennys 970 4100"; 
     } 
    } 
}
